Cloud-ready physical verification signoff solution

April 13, 2017 // By Jean-Pierre Joosting
Cadence Design Systems, Inc., has announced the Pegasus Verification System, a massively parallel, cloud-ready physical verification signoff system that enables engineers to deliver advanced-node ICs to market faster.

It is part of the full-flow Cadence digital design and signoff suite and provides up to 10X faster design rule check (DRC) performance on hundreds of CPUs while also reducing turnaround time from days to hours versus the previous-generation Cadence products.

Early adopters are already using the Pegasus Verification System for large-scale designs, across storage, high-performance computing, cloud, server and mobile applications.

Benefits include:

  • Massively parallel architecture: The system incorporates a massively parallel architecture that provides unprecedented speed and capacity, enabling designers to easily run on hundreds of CPUs to speed up tapeout times;
  • Reduced full-chip physical verification runtimes: Gigascale processing offers near-linear scalability that has been demonstrated on up to 960 CPUs, allowing customers to dramatically reduce DRC signoff runtimes;
  • Low transition cost: Using existing foundry-certified rule decks, customers achieve 100 percent accurate results with a minimal learning curve;
  • Flexible cloud-ready platform: Native cloud support provides an elastic and flexible compute environment for customers facing aggressive time-to-market deadlines;
  • Efficient use of CPU resources: A data flow architecture enables customers to optimize CPU usage, regardless of machine configurations and physical location, providing maximum flexibility to run on a wide range of hardware, achieving the fastest DRC signoff;
  • Native compatibility with Cadence digital and custom design flows: The Pegasus Verification System integrates seamlessly with the Virtuoso® custom design platform, delivering instantaneous DRC signoff checks to guide designers to a correct-by-construction flow that improves layout productivity. An integration with the Innovus™ Implementation System enables customers to run the Pegasus Verification System during multiple stages of the flow for a wide range of checks—signoff DRC and multi-patterning decomposition, color-balancing to improve yield, timing-aware metal fill to reduce timing closure iterations, incremental DRC and metal fill during engineering change orders (ECOs) that improve turnaround time, and full-chip DRC.
