Simulation tech enhances mixed-signal designs

Gemini Design Automation, a new company focusing on the setbacks of verifying complex analog and mixed-signal designs, has launched a fast SPICE-accurate simulation technology specifically designed to leverage the throughput advantages of multicore computing. The company said its native multithreaded technology has displayed runtimes and capacity of up to 30 times better than that of earlier-generation analog simulators, and up to 10 times enhancements over first-generation multithreaded approaches. The technology has been developed for three years and is being used in some production design environments, as well as benchmarked extensively against state of the art analog simulators, including multithreaded ones.

Gemini was conceived in 2005 by a team with extensive experience in the EDA industry, notably at Cadence Design Systems and Synopsys Inc. The core team, consisting of Baolin Yang and Xiaodong Zhang, has been involved with the development of other successful SPICE simulators and analog design environments. The team is supported by EDA industry pioneer, cofounder of Cadence, and EDAC Phil Kauffman Award winner James Solomon, considered as the foremost authority on analog design technology.

Yang said the product is the ideal solution for complex functions such as PLLs, ADCs and DACs, charge pumps, programmable Tx/Rx chains, power distribution circuitry and memory IP, particularly where there are many extracted post-layout parasitics, which need exhaustive verification prior to tape-out. It runs on standard X86 SMP multicore platforms equipped with 64bit Linux OS. Initial production product availability is scheduled for Q4 08.
