Cadence Introduces Spectre XPS, A New FastSPICE Simulator Delivering Up To 10X Faster Throughput

Cadence Spectre XPS

Cadence Design Systems, Inc. introduced Spectre XPS (eXtensive Partitioning Simulator), a high-performance FastSPICE simulator that enables faster and more comprehensive simulation for large, complex chip designs. The new simulator delivers ground-breaking partitioning technology that brings up to 10X faster throughput compared to competitive offerings, shortening simulation from weeks to days. Spectre XPS uniquely enables designers to accurately measure timing while including the impact of IR drop, making it ideal for advanced-node, low-power mobile designs, where high performance, accuracy and a greater capacity for post-layout verification are imperatives.

Cadence Introduces Spectre XPS, A New FastSPICE Simulator Delivering Up To 10X Faster Throughput

Chip design—driven by increasingly sophisticated applications and shrinking process geometries—continues to get more complex. At the same time, traditional FastSPICE technologies are no longer effective in meeting the verification challenges found at advanced nodes. Cadence’s new Spectre eXtensive Partitioning Simulator (XPS) fills a gap in simulation technology, providing capabilities that address increasing parasitics, low-power circuit structures, variation, and other advanced-node challenges.

Built on the leading Cadence Spectre simulation platform, Spectre XPS allows the easy re-use of models, stimulus, analysis and overall methodology, thereby reducing support costs while improving time to production. The unified Spectre simulation platform spans SPICE, advanced SPICE, RF and FastSPICE, enabling easy transition across analysis and flows; Spectre XPS integrates into the Virtuoso Analog Design Environment for mixed-signal design, and into the Liberate MX memory characterization tool for SRAM memory characterization.The faster throughput of Spectre XPS lets design teams conduct more thorough and accurate simulations for large memory-intensive designs, as well as low-power architectures that require greater visibility into parasitics. In addition to improvements in throughput, the new simulator requires two to three times less system memory than competitive offerings, improving compute resources utilization.
