In 2004, Virtutech accepted investment and moved its headquarters to San Jose, California.

This facilitates the development, testing, and debugging of embedded software that runs devices such as high-end servers, network hardware, aerospace/military vehicles, and automobiles.

Simics allows embedded software developers to create virtual models of hardware using an ordinary desktop computer, run specified sets of tests, and walk the programs through each step of execution, both forwards and backwards.
