Synopsys HSPICE Delivers Innovative Technology to Accelerate Circuit Simulation Performance
Advances in Core Engine Technology and Multi-core Processing Key to Performance Improvements

MOUNTAIN VIEW, Calif., March 10 /PRNewswire-FirstCall/ -- Synopsys, Inc. (NASDAQ: SNPS), a world leader in software and IP for semiconductor design and manufacturing, today unveiled improvements to its HSPICE® core engine technology that boost performance for complex analog and mixed-signal designs. In addition, new multi-threading capabilities in the March 2008 release of the HSPICE simulator speed up circuit simulation by taking advantage of new multi- core computer architectures. As a result, circuit designers can now run HSPICE post-layout simulations up to three times faster on single-core processors and up to six times faster on four-core processors.

"Implementing mixed-signal security processor designs in smaller geometries necessitates accurate transistor-level simulation with post-layout parasitics," said Jeff Berkman, chief technology officer at Priva Technologies, Inc., a company that develops and markets advanced hardware- and software-based authentication and security platforms for the travel, financial, retail, government and enterprise markets. "With post-layout parasitic data growing exponentially, having a fast simulation tool that can also take advantage of our investment in a multi-core compute platform is critical to the success of our circuit designs. We rely on Synopsys to deliver both the simulation technology enhancements and multi-core platform support required to increase our productivity and accelerate time-to-results."

The newest version of the HSPICE simulator delivers improvements in the symbolic DC operating point convergence algorithm, transient time-step control, netlist parsing and model performance. These enhancements accelerate overall simulation throughput on single-core computers.

Previously, HSPICE multi-threading capabilities allowed circuit designers to quickly simulate large pre-layout designs. With the March 2008 release, Synopsys has extended HSPICE multi-threading capabilities to enable simulation of large post-layout designs containing in excess of a million resistive and capacitive parasitic effects. As a result of these enhanced multi-threading simulation capabilities, fully extracted post-layout designs can now be simulated in just hours instead of days.

In a related announcement, Synopsys today announced the launch of its multi-core initiative to assist integrated circuit (IC) design companies in maximizing the throughput of their multi-core compute infrastructure to reduce time-to-results (TTR).

"Synopsys is deploying comprehensive support for multi-core processing across its core EDA and design-for-manufacturability product portfolios. The HSPICE circuit simulator is one of the first technologies to benefit from this effort," said Bijan Kiani, vice president of Product Marketing at Synopsys. "Full multi-threading capability in HSPICE enables designers to take advantage of their investment in a multi-core compute infrastructure and attain signoff- quality post-layout simulation results in a fraction of the time it takes with other simulators."
