SAN JOSE -- Cadence has acquired privately held foundation IP developer Altos Design Automation, the company said last night.

Terms of the acquisition were not disclosed.

Altos supplies tools to develop and characterize memory, standard cell libraries and other foundation IP, generating required models for SoC implementation. Combined with Cadence's Silicon Realization portfolio, the offering gives customers greater visibility into the effects of noise, timing and power at every phase of the design cycle, including foundation IP design creation, extraction, SPICE simulation, and implementation, Cadence said.

“Foundation IP characterization is becoming mission critical at advanced nodes due to shrinking time-to-market windows, escalating low-power, high-speed design complexities, and variations in advanced processes,” said Dr. Chi-Ping Hsu, senior vice president, research and development, Silicon Realization Group at Cadence. “By extending our Silicon Realization tool offering to include technically superior solutions that automate vital phases of the design process, we deliver the end-to-end approach that is required to ensure our customers’ success.”

Altos has over 30 customers, including 11 of the top 20 semiconductor companies.
