Abstract:
1. A method for exposing pre-diffused IP blocks in a semiconductor device for prototyping based on hardware emulation, comprising: connecting interface pins of at least two pre-diffused IP blocks in a semiconductor device to input ports of a multiplexer, wherein pre-diffused IP blocks are IP blocks in said semiconductor device whereon dopant has been deposited prior to diffusion; connecting an output port of said multiplexer to an I/O pin of said semiconductor device; providing an address to said multiplexer through a configuration pin of said semiconductor device to select which of said interface pins is actually connected to said I/O pin; and connecting said I/O pin to a reusable field programmable device so that a pre-diffused IP block having said selected interface pin is selected for prototyping.
