Cypress Semiconductor has licensed mixed-signal design tools from Antrim Design Systems that will be used in the semiconductor company's design centres around the world.
The tools will be used to help migrate Cypress' analogue cores to new processes. The Antrim tools are designed to speed up analogue simulations and to provide a level of analogue synthesis to generate cores that comply with a given specification.
Cypress performed a number of evaluations on both internal and external tools before picking the Antrim suite. The company is working on a range of communications-oriented designs that mix a significant amount of digital circuitry with analogue interfaces, demanding that the two are simulated together to catch potential problems.
Nelson Seiden, vice president of marketing for Antrim, said faster analogue simulation is becoming important to prevent respins in complex mixed-signal systems.
"It is the last-minute changes that kill people. The closer you get to tapeout, the more you tend to cut corners. Instead of running the full set of simulations, you may run just a few extreme cases.
"We can provide the ability to run all 16 simulations rather than the two or three extremes."
