<p>A method and system reuse data logs generated from testing of programmable devices in order to provide an input file of parameter values and settings for use in automatically configuring a device simulator. The programmable device testing process generates a data log output with data formatted so that parameter data are associated with unique variable labels The data log output file is processed in a parser operation that filters out private and unnecessary information, organizes the data and generates a Simulation input file in a format compatible with the simulator The process can be fully automated.</p>
