Synopsys Exalto is a post-layout electromagnetic-aware extraction and signoff product that models on-silicon EM coupling effects, produces S-parameter and rational function models for downstream simulation, and integrates with Synopsys signoff flows for post-LVS signoff.

| Starting Price | Not publicly listed | Not publicly listed | Not publicly listed or quote-based |
| Primary Fit | On-silicon EM-aware extraction and signoff integrated with Synopsys signoff flows | Calibre-centric verification/extraction organizations needing 3D extraction/field-solver capabilities | Broad 3D EM simulation across IC package/PCB/system interconnects; integration with Cadence design platforms |
| Key Strength | EM-aware coupling capture across hierarchy and integration with StarRC/IC Validator for signoff workflows | Strong fit where Calibre is already the signoff backbone; industry adoption for extraction and verification | Positioned for parallel EM simulation and integration with Cadence platforms |
| Key Weakness | Limited public benchmarks and user reviews; potential heavy compute demands; pricing opacity | May require different workflows if an organization is standardized on Synopsys signoff tools | Not primarily positioned as an on-silicon EM extraction signoff tool for IC-level parasitics and may be heavier than necessary for certain on-chip signoff tasks |
