Abstract

An Internet hardware description code generation system, methods, and scripts are provided. The Internet hardware description code generation system includes a hardware description code generation host adapted to generate one or more hardware description language files in response to one or more input parameters. A user uploads input parameters corresponding to a circuit to the hardware description code host. In response, the host generates one or more hardware description language (HDL) files that describe the circuit. Cgi scripts may be used to generate the HDL files.
