ANSYS RedHawk-SC

RedHawk-SC is the next-generation SoC power noise signoff platform to enable sub-16nm design success. RedHawk-SC is built on ANSYS SeaScape, the world's first custom-designed, big data architecture for electronic system design and simulation. SeaScape provides per-core scalability, flexible design data access, instantaneous design bring-up, MapReduce-enabled analytics and many other revolutionary capabilities. RedHawk, the industry gold-standard platform for SoC power noise and reliability sign-off, is being offered on the SeaScape platform as RedHawk-SC, giving you the best of both worlds — the signoff confidence that RedHawk provides and the elastic scalability and big data analytics of SeaScape.

ANSYS RedHawk-SC is the new standard for power noise and reliability sign-off for next generation designs that is production proven and silicon validated. The underlying elastic compute architecture has the scalability to solve the largest chips within a few hours. Big data analytics enable rapid data mining to drive actionable outcomes and optimization. RedHawk-SC can explore thousands of switching scenarios overnight, and prioritizes large numbers of vector sets by analyzing multiple different parameters. RedHawk-SC is built for multi-site collaboration, empowering you to simultaneously view, debug and explore design and simulation data. With RedHawk-SC, you can load the largest designs within seconds, run complex multi-variable analytics, drive design optimization and achieve faster design closure.

Elastic Compute Scalability
With unparalleled scalability across thousands of cores using big data techniques, ANSYS RedHawk-SC helps you sign off a billion-plus instance designs within a few hours on commodity hardware. No dedicated machines are needed — RedHawk-SC runs the largest designs, using low memory cores, even if they reside on different machines.

When RedHawk-SC launches, it  starts working as soon as a single core is available. It proportionately speeds up as more cores become available, and has the resiliency to recover should any core or machine become unresponsive. Because RedHawk-SC can utilize unused cores, it increases utilization rates of compute farms, thereby decreasing overall hardware costs; unlike other tools it does not require dedicated hardware, even for the largest designs.

This elastic scalability is what enables RedHawk-SC to process designs of unprecedented size with flat accuracy, high resolution extracted networks and multiple scenarios.

Big Data Analytics
Big data analytics enable rapid data mining and analytics to drive actionable outcomes and optimization. Using custom data analytics, you can identify and prioritize only those design fixes that are key to product success. Custom analytics powered by MapReduce enable you to query the largest designs in minutes. RedHawk-SC offers combined display and analytics across multiple views; heat maps for design quality check analysis; combined analysis across multiple scenarios for coverage analysis and issue diagnostics; and custom heat-map support.

Accelerated Design Closure
With the increasing number of cores in CPU and GPU sub-systems in next-generation SoCs,  it is crucial to understand and isolate the switching combination that can generate a chip-package-PCB resonance condition resulting in catastrophic voltage-drop-induced failure. RedHawk-SC leverages patented algorithmic approaches customized on the ANSYS SeaScape architecture to perform rapid design evaluation by exploring thousands of switching possibilities, and highlighting specific operating modes that should be avoided either through design or software level changes.

Design teams often struggle with understanding which vectors to use and which cycles within these vectors to simulate for signoff. Using RedHawk-SC’s multiphysics analytics, you can now “score” vectors across multiple parameters to identify the appropriate vectors and, more crucially, isolate cycles within these vectors that are important for power noise signoff. This will help you perform targeted simulations while getting meaningful coverage.

Multiphysics Optimization
For advanced process nodes,  margin-based design methodologies force overdesign and guardbanding, resulting in larger die sizes and increased design schedules. With RedHawk-SC you can perform multi-scenario simulations and run multiphysics analytics all within your design ECO cycle. With this methodology, you can target fixes in high stress areas while reducing overdesign in other parts of the chip. The design fix suggestions can be done quickly and efficiently through standard interfaces with existing place and route solutions. This has been proven over multiple successful tapeouts to reduce power consumption and die size while meeting performance and reliability targets.

Multi-site Collaboration using Thin Client Support
RedHawk-SC is built for multi-site collaboration and effective design analysis. Users across multiple sites can simultaneously view, debug and explore design and simulation results. You can bring up the largest designs in small memory machines in minutes and simultaneously view and optimize the same database across multiple sites.

Instantaneous Result and Native Layout Viewing with Full Hierarchical Support
RedHawk-SC allows simultaneous power and signal line analysis on a full-chip SoC with full hierarchical support. You can interactively view and monitor progress of the analysis while simulation is ongoing. You can also debug results with current heat maps that display nodes/edges for clear identification of the extracted circuit for advanced current flow and EM modeling.

Machine Learning Support
Machine learning support enables a wide range of applications, such as identifying missed systematic design weaknesses and automating time-consuming rigorous manual procedures. This is done by aggregating key insights across different designs using continuing and prior simulation and design data.

Comprehensive Dynamic Analysis Coverage
RedHawk-SC offers you the most comprehensive dynamic analysis coverage by
enabling you to sign off SoCs with confidence using a wide variety of simulation
modes — RTL and gate vectors; smart vectorless analysis for functional
and scan mode; mix-mode simulation (vectorless + VCD); and frequency-aware
vectorless to stress system level PDN, power-transient and power-up
analysis.

Chip Package Co-optimization
You can perform chip-package co-optimization by modeling the package and board for system-aware chip signoff and enabling chip power modeling for chip-aware system signoff.

Electromigration and ESD Signoff
RedHawk-SC offers comprehensive electrostatic discharge (ESD) analysis of HBM and CDM ESD events and power and signal electromigration (EM) analysis, in addition to advanced thermal-aware EM and statistical EM budgeting, which is a pressing reliability problem for sub-16nm designs.

Silicon-proven Signoff Leader
As the industry’s most silicon-proven SoC power integrity and reliability
signoff solution, supported by certifications from all foundries for every manufacturing process technology down to 7nm, ANSYS delivers the accuracy of its new RedHawk-SC for SoC signoff success.
