This pet product company needed a second source for five ASIC chips. A third-party circuit designer to create the circuitry for their product, but they did not have the expertise or tools to do the back-end of the design.
iSine did the specification reviews, LVS & DRC for the layout, test development and production.
The designs were done on time and worked in first silicon. iSine's recommendation that the circuit designer use larger device sizes and improved matching was not followed, so chip-to-chip variation had to be compensated through complicated software calibration.
