Automated, exhaustive Equivalence Checking
Questa EC by Siemens EDA is a formal verification tool that ensures functional equivalence between RTL and gate-level representations. It eliminates the risk of design mismatches introduced during synthesis and optimization — all without the need for simulation or testbenches.
Key Features:
- Automated Equivalence Checking – Formally proves functional equivalence between RTL and synthesized netlists.
- Sequential EC Support – Handles complex transformations like retiming, pipelining, and clock gating.
- No Testbench Required – Exhaustive formal analysis without simulation or stimulus generation.
- Multi-Stage Verification – Supports equivalence checking across RTL revisions, gate-level, ECOs, and timing-optimized netlists.
- Early Bug Detection – Catches synthesis-introduced logic errors before signoff.
- Root Cause Debugging – Pinpoints mismatch sources quickly with intuitive analysis tools.
- Optimized for Design Closure – Verifies aggressive optimizations with confidence.
- Broad Language Support – Works with SystemVerilog, Verilog, VHDL, and mixed-language flows.
- Flow Integration – Easily plugs into Siemens EDA implementation and verification workflows.
- Reduces Risk and Cost – Prevents expensive design respins and post-silicon surprises.
