Synopsys Inc. and Sigrity, Inc. announced that they unveiled an enhanced solution that accelerates signal integrity simulation of high-speed systems. In the latest release of the HSPICE circuit simulator, Synopsys Inc. has employed in-memory communication to deliver deeper integration with Sigrity, Inc.'s signal integrity analysis offerings. In addition, the HSPICE 2011.09 release provides enhanced multi-core simulation performance, improved accuracy in statistical eye-diagram analysis, and new multi-core enabled S-parameter and W-element analysis. The combined Synopsys and Sigrity solution offers up to 3X faster simulation of signal and power integrity analysis of multi-gigahertz designs. Sigrity, Inc.'s solutions are widely used with HSPICE for signal, power integrity and electromagnetic interference analysis of high-speed boards, packages and integrated circuits. Sigrity tools generate interconnect models in either a traditional format or in Sigrity, Inc.'s Broadband Network Parameter (BNP) format, which contains richer frequency domain data in a compact format. HSPICE 2011.09 has been enhanced to support the BNP format using a unique API that facilitates direct in-memory communication between HSPICE and Sigrity, Inc.'s electromagnetic solver, improving simulation throughput, accuracy and convergence.
