Cadence Design Systems Inc. has announced that it acquired fellow EDA vendor Altos Design Automation Inc. Financial terms of the deal were not disclosed.

Altos provides tools that enable fast, accurate characterization of memory, standard cell libraries and other foundation IP, generating required models for SoC implementation. Cadence says that when combined with Cadence's end-to-end Silicon Realization portfolio, the offering gives its 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.

Altos was founded in January 2005 by former employees of Cadence and CadMOS Design Technology, a physical layout and signal integrity software startup that was acquired by Cadence in 2001. Altos founders include Jim McCanny, Altos CEO and former timing and signal integrity marketing group director at Cadence; Ken Tseng, Altos chief technology officer and a former architect at Cadence; Kevin Chou, Altos vice president of R&D and former senior member of Cadence's consulting staff; and Wenkung Chu, Altos R&D architect and also a former senior member of Cadence's consulting staff.

A spokesperson for Cadence did not immediately respond to an inquiry about whether the founders and other employees of Altos would join Cadence as a result of the acquisition.

But a statement issued by Cadence quotes McCanny saying he was "looking forward to working with Cadence to further exploit the capabilities of our characterization technology, and help deliver a more powerful combined solution that overcomes our customers' most difficult design challenges."

"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," says Chi-Ping Hsu, senior R&D vice president in Cadence's Silicon Realization Group. "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 more than 30 customers, including 11 of the top 20 semiconductor companies, according to the statement issued by Cadence.
