Spectre eXtensive Partitioning Simulator (XPS) 


Unique FastSPICE algorithm delivers up to 10X faster simulation throughput

Delivering high performance and capacity, Cadence® Spectre® eXtensive Partitioning Simulator (XPS) FastSPICE simulator provides fast, accurate simulation of large, memory-intensive and mixed-signal designs. The simulation solution is integrated into the Cadence Spectre Circuit Simulator infrastructure, so you can use the same models, process design kits (PDKs), and methodology to verify your design.

Reduce Memory Simulation Time from Weeks to Days
Traditional FastSPICE technologies are no longer effective in meeting the verification challenges found at advanced nodes. Cadence Spectre XPS fills a gap in simulation technology, providing capabilities that address increasing parasitics, low-power circuit structures, variation, and other advanced-node challenges.

With its unique partitioning technology and new FastSPICE algorithm, Spectre XPS supports:
  • Higher capacity and up to 10X faster simulation throughput while requiring up to 3X less system memory
  • Accurate timing and power analysis for advanced-node, low-power embedded memory applications
  • Shortened simulation time from weeks to just days
Improve Mixed-Signal Design
The increased complexity and functionality of many mixed-signal designs, such as phase-locked loops (PLL), analog-to-digital converters (ADC), logic, and power management, require new simulation solutions that provide a trade-off between accuracy and performance. Building on the results accuracy you are used to with Spectre Accelerated Parallel Simulator (APS), the Spectre XPS algorithms integrated into the Spectre infrastructure:
  • Enable complete re-use of your existing Spectre methodology, PDKs, models, and commands, greatly reducing the cost of maintaining multiple simulation solutions
  • Provide a seamless methodology for making the accuracy/performance trade-off
