GUC and Ansys Expedite Advanced-IC Designs for Next-Generation Applications with State-of-the-Art Simulation Workflow

Ansys’ new workflow cuts model setup time from hours to minutes, runs simulations 2-3x faster, and expedites the integration of GUC die-to-die solution for ASICs

Key Highlights

  • GUC engineers are using Ansys HFSS 3D Layout’s advanced simulation workflow to speed advanced integrated circuit (Advanced-IC) design 
  • Theworkflow helps GUC rapidly incorporate its die-to-die solution across CoWoS (Chip-on-Wafer-on-Substrate), InFO (Integrated Fan-Out) and interposer designs to create leading-edge artificial intelligence (AI), high-performance computing (HPC) and data center networking customer ASICs

PITTSBURGH, PA, March 25, 2021 Global Unichip Corporation (GUC) is adopting a groundbreaking simulation workflow developed by Ansys (NASDAQ: ANSS) to accelerate Advanced-IC design. The workflow enables enhanced innovation across CoWoS, InFO and interposer designs, including GUC’s newly announced, silicon-proven GUC multi-die interLink (GLink) interface, which is essential for developing leading-edge AI, HPC and data center networking applications.

To maintain market leadership, GUC engineers must create, simulate and optimize Advanced-ICs with unprecedented speed, achieving first-pass design success and optimal device performance. However, major roadblocks stall the simulation process, especially in complex areas such as CoWoS, InFO design manipulation and device meshing.

GUC delivers the industry-leading die-to-die interconnect solution for advanced customer ASICs.

Ansys HFSS 3D Layout’s workflow empowers GUC engineers to simulate faster and solve challenging geometries by incorporating several innovative tools, including ECADXplorer — a powerful new GDS editing platform that simplifies design manipulation to drive rapid simulation. Integrating cutting-edge meshing technologies coupled with Ansys’ industry-leading 3D HFSS solver, the workflow reduces simulation set-up time from hours to minutes. This helps GUC Advanced-IC designers efficiently extract S-parameter models of their devices with the highest fidelity. Additionally, it spurs the development of game-changing technologies such as GLink, which provides 6-10 times less power consumption than an alternative solution and occupies two times less silicon area.

“Advanced-IC package designs are highly sophisticated due to the ever-growing demand for increased functionality and lower power consumption within a smaller footprint. The strong momentum of GLink adoption by our AI, HPC and networking customers supports our commitment to building a wide IP portfolio and deepening GUC’s advanced packaging design expertise," said Igor Elkanovich, chief technology officer at GUC. “HFSS 3D Layout helps our engineering team decrease Advanced-IC design complexity, integrate heterogeneous chips and improve multi-chip performance to ensure customers receive new AI, HPC and Data Center Networking products much sooner.”

“Through this enhanced workflow, Ansys increases the productivity for GUC Advanced-IC designers by significantly simplifying the design process,” said Shane Emswiler, senior vice president at Ansys. “Leveraging HFSS 3D Layout, GUC engineers are swiftly creating fully parametric models, performing design studies of electronic packaging and exploring more design options than ever to evaluate tradeoffs prior to production — delivering considerable reductions in development time and expense.”
