Abstract

Arrangement and method for simulating electro-mechanical systems includes a simulator for simulating an operating environment of a plurality of different electro-mechanical systems, a first interface unit for enabling the simulator to interface with a host computer and input/output devices, and a second interface unit for enabling the simulator to be reprogrammed and re-configured to enable simulation of the operating environment of the different electro-mechanical systems. The simulator may include a user-programmable field programmable gate array and a digital signal processing unit coupled to the field programmable gate array.
