Exhaustive verification long before simulation test environments is available
Questa Property Checking is Siemens EDA’s formal solution that verifies RTL against user-defined assertions early in the design cycle—long before simulation is available. It catches complex bugs by exhaustively exploring all valid design states.
Key Features:
- Assertion-Based Verification – Uses SVA, PSL, and OVL to verify RTL behavior without simulation.
- Full-State-Space Exploration – Breadth-first formal analysis uncovers corner-case bugs unreachable by testbenches.
- No Testbench Needed – Just assertions and constraints are enough to begin verification.
- Early Bug Detection – Verifies design intent during RTL development, preventing late-stage surprises.
- Coverage-Aware – Tracks progress with UCDB integration for unified verification tracking.
- Visual Debug Tools – Failure waveforms, counterexamples, and schematic traces speed up root cause analysis.
- Post-Silicon Debug – Replays field issues to confirm fixes and prevent recurrence.
- Scalable & Fast – Uses high-throughput engines to handle large designs with many assertions efficiently
- Multiclock Support – Verifies complex clock-domain behaviors with multi-clocked assertions.
- Seamless Integration – Shares language frontend and UCDB with QuestaSim and other Siemens tools.
