Synopsys PrimeSim XA is a FastSPICE-class transistor-level circuit simulator that provides increased capacity and faster runtimes while preserving SPICE-level accuracy for signoff-quality SRAM, custom digital, and mixed-signal verification.
Published Sep 12, 2026
| Starting Price | Not publicly listed | Not publicly listed | Not publicly listed |
| Primary use case | SRAM, custom digital, mixed-signal FastSPICE capacity and transistor-level verification | Large-scale analog/RF/mixed-signal verification with parallel simulation capabilities | High-speed nm-accurate circuit verification for analog/RF/mixed-signal/custom digital |
| Key strength | Positioned for SRAM and mixed-signal full-instance simulation; integrated with PrimeWave and PrimeSim Continuum | Integration with Cadence custom design flows and parallel simulation capabilities | Foundry-focused SPICE accuracy claims and element capacity for post-layout verification |
| Key weakness | Limited publicly available third-party reviews and limited public security/pricing disclosures; potential switching costs for non-Synopsys environments | Cadence ecosystem cost/complexity and licensing model considerations | Public materials require benchmarking per-design to validate vendor-stated speed and capacity claims |
