High-Performance Design with Rapid RTL Profiling of Critical Power Scenarios
9:30 AM - 10:00 AM PDT
High current events (di/dt) in the SoC are the result of the sudden high current demand caused by a large number of simultaneous switching activities from the workload. Unless appropriate mitigation strategies are in place, these di/dt events can cause significant voltage drops in the power grid. From an analysis of RTL level switching activity profiles of representative workloads and their dynamic power profiles, the critical windows where adverse di/dt events might occur can be revealed. Consequently, RTL stage solutions for better Power & Performance can be implemented in a timely manner, during the design phase.

Laying the Foundations for Optical Pass-Through Links’ Design
9:30 AM - 10:00 AM PDT
Optical pass-through (OPT) links have been proposed in scalable, always on, all-to-all (A2A) connected switchless optical networks as a promising solution to reduce the amount of connections against A2A network fabrics based on a brute force approach. Thus, it is of crucial importance to understand the design challenges, if any, of optical links for intra-node communications. In this work, we propose, for the first time, a design-space exploration that leverages the bit error rate (BER) performance to evaluate the viability of OPT links in serviceable high-performance computing systems. In particular, we use Ansys Lumerical INTERCONNECT to analyze the BER performance for optical links at 16 Gbps.

A Multiphysics Simulation Flow for High Performance MMIC Products for 5G and RF Applications
9:30 AM - 10:00 AM PDT
Pressure on cost and performance of MMIC products for 5G and RF applications requires EM-based optimization of designs to gain competitive advantage. Moreover, the need to reduce size requires packing many components in a limited space, leading to increased temperatures. To make sure that such temperatures and the related mechanical stress levels remain under reliability limits, Multiphysics simulations are needed at system level, including chip, package, board and cooling blocks. To tackle this challenge, Ampleon engineers use Ansys tools. In more detail, Raptor X is used to simulate full MMIC designs on low-resistivity substrates, which are especially challenging to model due to the slow-wave propagation. Ansoft 3D layout is used to import the layout into Electronic Desktop (AEDT) where it is combined with board, package, and cooling blocks for system level Multiphysics simulations in AEDT/Mechanical. At this stage, engineers are not only able to optimize system designs to make sure that temperature and stress levels remain under safe limits, but also to explore different cooling options. Having EM and Multiphysics tools under the same roof with a simple interface improves efficiency, boost productivity, and enables cutting-edge designs of high-performance products and allows Ampleon to save costs gaining market competitiveness.

A Novel Methodology for EM/IR analysis of Complex LDO/Power Gated Designs
9:30 AM - 10:00 AM PDT
RF/Automobiles chips are more complex in designs and operate at ultra-high frequencies. Qualcomm custom devices make the design complex compared to other analog and digital designs. Hence there is a requirement for a flow which is dynamic, schematic/layout driven, and which supports the complexity in the chip designs and meet Qualcomm chipset criteria of EM sign off. When head switches and regulators are present, It is even more difficult to make the setup for the end users. In conventional flow, the internal net was brought to the top level and analyzed. The critical part is that we have an internal P/G domain which cannot be always defined as global due to same names at the next hierarchies sometimes. The tool needs to be more intelligent to handle multiple domains at different levels. The paper presents a novel methodology with a customizable GUI flow to extract the internal P/G domains and to handle the P/G domains after head switches and regulators which are not directly connected to voltage sources.

Accuracy and Performance benchmarks for Gate-level Power Integrity Signoff with RedHawk-SC Advanced Power Analytics
9:30 AM - 10:00 AM PDT
It has been a known challenge to signoff PDN for gate-level netlist with gate vectors as the vectors are not available until late in design cycle. For PDN signoff, currently the designers either wait for gate vectors to be available or simulate RTL vectors using simulation tools. However, using RTL vectors with gate netlist brings their own challenges with regards to name-mapping differences between the two; low coverage of RTL FSDBs on combinational logic; need of accurate delay-aware event propagation and runtime performance issues for multi-mode long RTL vector sets. In this paper we present the results of accuracy and performance benchmarks for Long Vector Simulations in Automotive SoC usecases using Dynamic Power View (RedHawk-SC Advanced Power Analytics Platform). The tool uses distributed SeaScape architecture to provide detailed analysis of multi-corner, multi-domain, cell/clock/hierarchy wise debug reports, smart auto-name mapping algorithm with flexibility to add user mapping files to drive 90%+ mapping coverages and fast & accurate event propagation for long (ms+) RTL Vectors on SoC designs with multi-million gate count. The results from gate power on a reference automotive SoC design are within 10% of Silicon, with couple of hrs of scalable performance runtimes. The Dynamic Power View is also leveraged for accurate cycle-by-cycle power over time analysis to drive multi-mode power analysis for EMIR Power Integrity Signoff.

SigmaDVD: High Coverage Solution for Power Integrity Signoff
10:00 AM - 10:30 AM PDT
SigmaDVD (sDVD) is a unique simulation method that provides complete power grid noise coverage for 100% of the design instances. This novel simulation technique generates tens of thousands of unique switching scenarios for each instance independently, using Monte Carlo techniques, and gathers the results into a distribution with a known three-sigma DVD value (sDVD) per instance. This analysis closes a known gap in power grid noise coverage available from other methods, such as vectorbased and vectorless direct transient simulations as well as BQM. The main considerations when comparing this new IR-Drop flow with other techniques are coverage (what % of hotspots from other IR-Drop methods does sDVD cover?) and how to handle the increase in hotspots/violating instances caused by the massive increase in noise coverage. We quantified this new flow's coverage capabilities through heatmap comparisons. In this presentation, we will first discuss the theory of sDVD, various trials we conducted to compare sDVD with other IR-Drop methods, and main conclusions (such as cost/coverage) based on our analyses. To demonstrate the added value from sDVD, we investigated sDVD's coverage of post-silicon identified outliers.

A Comprehensive Thermal Solution in Advanced Large Scale 3DIC Design

A Comprehensive Thermal Solution in Advanced Large Scale 3DIC Design
10:00 AM - 10:30 AM PDT
The pursuit of high integration and high performance 3DIC design makes the number of cells per unit area of the chip increase and thermal coupling between cell is intensified. Meanwhile, with narrow 3-D fin structure and lower thermal conductivity in substrate, local FinFET device temperature is higher compared to planar MOS structure. In addition, the joule heat between wires in limited space becomes severe. Narrower physical wires, higher current density, increasing impact of wire temperature on EM limit, all these factors can lead to rise of the chip temperature and worsen the electromigration(EM) phenomenon, such as open or short. To avoid function failure caused by reliability-related problems, designer restricts the design excessively with whole die set to a value higher than the maximum operating temperature in traditional flow, which causes difficulty to iterate and even failure to sign-off. So the accurate "Thermal aware EM sign-off" is a must for advanced 3DIC design. Different from the traditional flow, our flow can model the realistic heat dissipation environment of the complicated 3DIC accurately, and meanwhile take the thermal coupling of the instance, and the wire-to-wire joule heat into account to analyze the thermal convergence process precisely. For different layers and locations, different temperatures (Tj) are generated. The realistic spatial tempatrue distribution scenario generated by system-level thermal analysis can replace the coarse global temperature setting in traditional EM analysis flow. With the thermal-aware EM flow, we can avoid over-design and under-design. And the simulation results can be used to provide guidance for the heat dissipation design of the system. keywords : thermal-aware, EM-analysis, boudary condiction, system-level

Graphics workload-based power trends and optimizations using PowerArtist
10:00 AM - 10:30 AM PDT
This presentation is about analyzing real-world workloads on GFX RTL designs, emphasizing the discovery of optimization opportunities not easily discerned through synthetic vectors or unit-level testing. The challenge lies in efficiently processing stimuli involving tens of millions of cycles on designs of multiple million instances all within a reasonable timeframe of less than 48-hours. In PowerArtist, this can be achieved by enabling the distributed GAF (using FSDB) based reduction flow. We also utilize the average power data computed using SAIF to track relative power trends through automated regressions at the GFX IP level. This approach resulted in the discovery of significant power optimization opportunity at the GFX IP level. Furthermore, it helped us successfully identify regressions in power between two successive versions of the GFX IP using relative RTL trend tracking technique. Overall, this helps with left shifting the GFX IP level power analysis and optimization effort and avoid late RTL surprises. This directly translates into better perf-per-watt for the product.

Leveraging Scan Vectorless for ATPG Robustness
10:00 AM - 10:30 AM PDT
Typically, IR drop analysis targeted only for the functional mode use cases. ATPG modes, especially stuck-at-fault analysis in Design for Testability (DFT) is not considered for DvD as the frequency of operation is lower. However, in scan mode, simultaneous switching of large number of registers give rise to high peak current and di/dt effects which, when coupled with package inductance is bound to introduce significant IR drop issues. It also captures secondary effects such as unintentional switching in the data path and combinational logic downstream of the flops. VCD based analysis is the most common method to annotate the activity on the scan flops. However, securing the VCDs for multiple cores and the duration of VCDs to cover switching activity of all scan chains is a huge challenge. This paper talks about the work done to perform vector less scan mode analysis, using an early-stage design data without the need of gate VCD which is available very late in the design stage. This RedHawk-SC based scan vector less flow demonstrates a unified setup which provides seamless method to consume scan chain configuration along with the pattern annotation without involving heavy vector generation process. The irdrop results from this method correlates very well with the actual VCD based dynamic irdrop analysis.

Early IR Drop Prediction Using Machine Learning for Power Grid
10:10 AM - 10:30 AM PDT
Meeting voltage drop specification has been an increasing challenge with process node shrinking, increase in layer stack and increase in power consumption. In custom design, power grid generation are not IR driven today. Grid gets implemented in layout first and then verified by tools on its robustness. This involves multiple iterations sometimes in advanced stage of design milestones which creates challenges in implementing layout edits as well as disturbs converged parameters and impact schedules. We propose a machine learning (ML) solution which works at the power grid definition phase of a custom IP, it tries to predict block level IRdrop on a given specification when no layout and placement information is available. It uses physical and electrical specifications as features to train the ML model. User can tune metal layer, width & pitch values to derive optimal power grid to proceed for physical implementation. The training data sets are design testcases run with IR analysis tools. Appropriate features like block dimension, metal layers, width, pitch of power grid are extracted along with IRdrop results for the testcases.

Silicon Interposer Extraction Using Ansys RaptorX
10:30 AM - 11:00 AM PDT
Silicon interposers are an important technology to increase the functionality of electronics while reducing the power consumed and size required. Electromagnetic modeling of silicon interposers is required to achieve this reduction. The Ansys RaptorX solver is perfect for modeling silicon interposers. This presentation will demonstrate the capabilities RaptorX has which make it well suited for extracting silicon interposers. Those capabilities are capacity, speed, accuracy, the ability to model through silicon vias (TSVs), and the ability to model deep trench capacitors (DTCs). These capabilities are demonstrated by extracting an interposer with signal nets, ground nets, power nets, TSVs, and DTCs. The extraction results are shown and discussed.

SPICE Validation of Dynamic Voltage Drops from SigmaDVD
10:30 AM - 11:00 AM PDT
Dynamic voltage drop (DVD) is an escalating problem as technology nodes shrink. Traditional DVD analysis methods lack necessary coverage to identify the location and magnitude of DVD hotspots. New tools, such as the SigmaDVD technology in Ansys RedHawk-SC, aim to improve DVD accuracy and coverage. In this work, we present results from a circuit targeted to validate SigmaDVD results. This circuit is simulated in SPICE with a fully extracted power grid, using non-Ansys tools. This validation method has been used to enhance the algorithms used by SigmaDVD, resulting in significant accuracy improvement. Analysis of one specific enhancement will be demonstrated in detail. The importance of properly accounting for correlated activity will be also discussed.

Thermal Aware Vectorless EM/IR Sign-off for Custom-IPs
10:30 AM - 11:00 AM PDT
For High Speed Mixed signal IPs, custom digital designs are prone to EM/IR issues due to high frequency paths and custom drawn layout. At the same time, testbench setup with worst case vectors is a big challenge along with coverage concern in such simulation based run. As an alternative, vectorless mode EM/IR provides desired coverage and worst case analysis for EM purpose. Even though EM/IR is covered through heuristic based approach in industry standard tools, there's no equivalent thermal solution to include Self heat effect for transistors. This paper talks about a novel characterization based approach to mitigate Self heat risks for above mentioned designs. As a part of the solution, vendor EDA tool runs a design specific transistor characterization with Simulation models to compute thermal resistance of each transistors. Later in the flow vectorless engine calculated power is used along with the derived thermal resistance to compute device deltaT profile used by Self heat analysis.

An Accurate System-level Transient Droop Analysis Methodology for High Performance GPGPU Power Delivery Network
10:30 AM - 11:00 AM PDT
GPGPU is commonly used in data-center, AI and high performance computing systems. To achieve higher computing performance and bandwidth, the growing current demand of GPGPU makes the power delivery network(PDN) design become more and more challenging. In this paper, we proposed an accurate system level transient voltage droop simulation methodology for high performance GPGPU PDN design and optimization. The accuracy of voltage droop mainly depends on current profiling and accurate PDN modeling. Firstly, we developed an accurate and efficient current profiling flow for system level voltage droop simulation. We used the gate level current profile to achieve result accuracy and take the advantage of RTL level current profile generated from Ansys PowerArtist tool to improve simulation efficiency. With combined usage of gate level/RTL level current, we’re able to shift PDN design to RTL design stage and to do quick iteration with accuracy. Secondly, we presented a novel PDN power model extraction methodology with board, socket and package design merged. This way enables us to consider accurate socket model impact compared with traditional separate model extraction way. Lastly, we did voltage droop lab measurement to verify the accuracy of simulation flow. The simulated voltage droop is well correlated with the measurement result.

Accuracy and Performance benchmarks for Gate-level Power Integrity Signoff with RedHawk-SC Advanced Power Analytics
10:30 AM - 11:00 AM PDT
It has been a known challenge to signoff PDN for gate-level netlist with gate vectors as the vectors are not available until late in design cycle. For PDN signoff, currently the designers either wait for gate vectors to be available or simulate RTL vectors using simulation tools. However, using RTL vectors with gate netlist brings their own challenges with regards to name-mapping differences between the two; low coverage of RTL FSDBs on combinational logic; need of accurate delay-aware event propagation and runtime performance issues for multi-mode long RTL vector sets. In this paper we present the results of accuracy and performance benchmarks for Long Vector Simulations in Automotive SoC usecases using Dynamic Power View (RedHawk-SC Advanced Power Analytics Platform). The tool uses distributed SeaScape architecture to provide detailed analysis of multi-corner, multi-domain, cell/clock/hierarchy wise debug reports, smart auto-name mapping algorithm with flexibility to add user mapping files to drive 90%+ mapping coverages and fast & accurate event propagation for long (ms+) RTL Vectors on SoC designs with multi-million gate count. The results from gate power on a reference automotive SoC design are within 10% of Silicon, with couple of hrs of scalable performance runtimes. The Dynamic Power View is also leveraged for accurate cycle-by-cycle power over time analysis to drive multi-mode power analysis for EMIR Power Integrity Signoff.

Early Clock Tree Power Correlation at SOC: A Case Study
11:00 AM - 11:30 AM PDT
The clock tree power is one of the critical aspects to be estimated and analyzed for an SoC, as the clock network power contributes to major share in overall power of the chip. Typically, clock power estimations and analysis is performed at gate level which is late in the cycle (CTS stage), which would not provide any room for design optimization due to stringent timelines of SOC execution. So, it will be very useful to have early estimation of power on RTL, which provides more scope to optimize the design for power, much earlier in the design cycle. This paper discusses the advantages and challenges of extracting clock tree power on RTL by deploying PowerArtist tool and finding out the areas of improvement in design which helps in optimizing the design for better quality in terms of power. This paper also discusses the challenges running the PowerArtist at SOC level and provides suggestions to optimize the runtimes and report analysis.

Aggressor Aware Design for Improved IR-Drop Results
11:30 AM - 12:00 PM PDT
The move to advanced technodes has many benefits, but it has created a challenge that has been previously neglectable; the aggression of neighbouring cells that are linked through the power grid – this link through the grid is known as cross-impedance. The complex grid structure that designed with pillars create cross-impedance that stretch beyond cells that share same track. Traditionally the focus of IRdrop analyses was mainly 2 aspects: i) improving self-drop –optimizing the cell’s resistive path from its power pins to the bumps. ii) handling simultaneous switching cells that share a power\ground track. To improve turn-around-time and reduce IRdrop related ECO cycles, we can tackle the problem from its origin – we can leverage Ansys Redhawk-SC platform to gather and calculate the aggression impact radius for all the cells in the library. The gathered data can be transformed to custom placement rules that will maximize cell usage while reducing overall dynamic IRdrop. At later mature design stages, we can utilize Ansys Redhawk-SC platform to combine aggressor cells in the design with their slack to a small and effective list of ECO’s that will have most overall design IRdrop improvements while having minimal impact on timing due to slack margin.

This paper describes a holistic design and simulation tool deployed for virtual prototyping of semiconductor power modules. The power module designer proceeds from concept to virtual prototype in a logical and comprehensive flow. Starting with a simple 2D DXF of the Direct Bond Copper (DBC), the module is designed through die selection and placement, layer and material property declaration, electrical connectivity, and external port definition. Automated 3D model generation is carried out through advanced Ansys scripting techniques. Multiple levels of simulation and model generation are executed through Ansys Icepak, Ansys Q3D, and SPICE. The tool has been validated on multiple onsemi Silicon-Carbide (SiC) industrial and automotive traction power modules.
