I’ve been using ADE-XL to run corner simulations lately. I like that it lets me set up a specification for simulations (AKA a scoreboard) and then runs through different corners. And it supports distributed or parallel computing. But getting things like corner definitions in there is difficult. You’d have to hand-enter them. Luckily, Cadence […]
