AnSem - Your partner in analog, RF and mixed-signal ASICs

The leading fabless analog ASIC Design Service company
AnSem specializes in designing and delivering state-of-the-art analog,
RF and mixed-signal integrated circuits to customers worldwide.

AnSem complements industry standard EDA tools with a proprietary EDA sizing tool and automation scripts. The Matlab based sizing program allows quick and efficient circuit design through a formal description of the sizing of transistors. All steps in the design flow are linked with Matlab and Python based scripts. Toplevel simulations at transistor level as well as with behavioral models, together with regression testing, with a goal of 100% simulation coverage across all corners , ensure AnSem’s first time functional success rate. Monte Carlo and circuit startup simulations on the backannotated netlist, together with EMC/EMI simulations and at speed digital testing can be added to the design to support the automotive goal of 0ppm over the lifetime of the IC.
