SUNNYVALE, Calif. -- Design automation and verification tool supplier Simplex Solutions Inc. today announced it has acquired the software intellectual property (IP) assets of the Coyote Systems business from Coventor Inc.
Simplex said it paid $2.5 million in cash for the IP assets, including Coyote's AutoIC product line, which the company claims is the world's fastest three-dimensional field solver. The acquisition is aimed at strengthening Simplex's position as a leading supplier for enhanced modeling software for 0.13-micron and below IC designs.
"Accurate process modeling is the foundation for first-silicon success," said Penny Herscher, chairman and CEO of Simplex. She added that the acquisition backs up her company's "commitment to continuous investment in this strategic area."
"Every technology, product and service that we provide will benefit from this acquisition," said the chief executive officer. "Our SoC system-on-chip verification customers will tapeout 0.13-micron and below designs with confidence in first-silicon results. Our SoC Design Foundry will push customer designs even closer to the outer limits of process performance," Herscher promised.
Just as important, Simplex's efforts to promote diagonal interconnects on ICs--called the "X Architecture"--which the company says will improved simplify chip layouts and dramatically reduce power consumption. The architecture is backed by a consortium, which was launched last summer (see June 4 story). The X Architecture's diagonal wiring approach "presents the greatest possible technical challenge in terms of capacitance modeling," said Herscher, who added that the concept "absolutely requires this technology" from Coyote Systems.
Under the acquisition agreement, key technologists from Coyote Systems will join Simplex's development team, said the company.
Simplex said 3-D field solvers are used to create and validate the accuracy of semiconductor process models. At 0.13-micron feature sizes and below, deep-submicron (DSM) effects--particularly coupling capacitance-become increasingly complex, noted the Sunnyvale-based design automation supplier. Simplex said current-generation field solvers do not model coupling capacitance with adequate accuracy for 0.13-micron and below design rules.
According to Simplex, the Coyote 3-D field solver provides accurate coupling capacitance modeling at least 10 times faster than other tools.
"Our experience using the Coyote technology in the development of models for the X Architecture convinced us that this technology would become the standard for next-generation modeling, for both Manhattan conventional right-angle interconnect grids and X Architecture designs," said Jim Bailey, vice president and general manager of Simplex's SoC verification business.
