Design Synopsys has acquired Sandwork Design, a privately held, Mountain View, Calif.-based provider of analog and mixed-signal (AMS) verification solutions. Sandwork's approach to verification enables engineers to analyze and debug complex AMS systems-on-chips. Sandwork's products, combined with Synopsys' industry-leading Discovery AMS solution, deliver a environment for verification and debug. Terms of the deal are not being disclosed. Already interoperable with the Synopsys Discovery AMS simulators HSPICE, HSIM and Nanosim, the Sandwork tools include SPICE Explorer, a transistor-level design debugging environment, WaveView Analyzer a AMS waveform analyzer, and SpiceCheck for electrical rule checks of transistor-level netlists. All Sandwork products are available through the local Synopsys sales offices.
