Key Benefits

  • High-performance, high-capacity SPICE-level analog and RF simulation out of the box
  • Integrated with the Virtuoso ADE Product Suite for user-friendly simulation setup for the most complex analog and custom-digital ICs, facilitating accuracy/performance tradeoff
  • Accurate, efficient post-layout simulation with RLCK parasitics, support for blocks modeled with S-parameter models, and lossy coupled transmission lines

The Cadence® Spectre® Circuit Simulator provides fast, accurate SPICE-level simulation for analog, radio frequency (RF), and mixed-signal circuits. It is tightly integrated with the Cadence Virtuoso® custom design platform and provides detailed transistor-level analysis in multiple domains. Its superior architecture allows for low memory consumption and high-capacity analysis.
