EHWPack: a Parallel Software/Hardware Environment for Evolvable Hardware

摘要

This paper describes the EHWPack development system, a multi-tasking parallel software tool that performs the evolutionary synthesis of electronic circuits, using the SPICE simulator and the Field Programmable Transistor Array hardware (FPTA) developed at JPL (Stoica, 1999). EHWPack integrates free and commercial software packages such as PGAPack for the evolutionary algorithm, Spice 3F5 for the circuit evaluation, Tcl-Tk for the graphic interface, and LabView for the hardware evaluation. The paper investigates the performance of the tool in two typical problems of EHW: evolutionary synthesis of a Gaussian computational function and the evolution of a band-pass filter.
