SAN JOSE, Calif. — (BUSINESS WIRE) — March 19, 2013 — At DATE 2013, Calypto® Design Systems, Inc., the leader in electronic system level (ESL) hardware design and register transfer level (RTL) power optimization, will present in a technical session on an innovative approach to detecting isomorphisms in logic design and formal verification. This work is based on collaboration between Calypto and UC Berkeley that is aimed at simplifying formal analysis of circuit logic. Calypto technologies let designers create high-quality, low power ASIC and FPGA hardware products. Calypto’s three product families (PowerPro®, Catapult® and SLEC®) offer customers solutions ranging from RTL power reduction to C++/ SystemC high-level synthesis.

This presentation describes a way to use simulation to quickly identify isomorphisms. By repeatedly simulating the netlist, unique signatures for each gate are derived. If two netlists, simulated separately, have the same signatures then these netlists are isomorphic. Any results computed on one netlist can be safely applied to the second netlist, leading to dramatic speedups overall.

The results presented in this session focus on sequential equivalence checking, and for this purpose, isomorphic proof obligations are identified. If two proof obligations are isomorphic, then the tool only needs to derive a formal proof for one of the obligations, thus reducing the total number of proof obligations that need to be considered. In this presentation, we look at a variety of industrial equivalence checking testcases and demonstrate that:

• This simulation-based approach can identify the isomorphic proof obligations in mere seconds.
• On average, the number of proof obligations is reduced by 61%.
• The time needed to prove the proof obligations is reduced by 60%.
