Computer-aided prototyping for ASIC-based systems

The use of computer-aided prototyping (CAP) with the RPM Emulation System is described. RPM creates a hardware functional prototype from an ASIC or full-custom chip netlist. It reads the chip netlist and then converts the chip design gates into a prototype design. It then synthesizes the prototype design, obtaining the information it needs to configure the reprogrammable hardware, primarily with partitioning and placement and routing technology. Finally, it physically implements the prototype design by electronically configuring the reprogrammable hardware. RPM includes embedded tools for interactive debugging with access to any internal design node, and a facility for handling quick incremental changes to the design. It is argued that other techniques such as silicon prototyping and manual prototyping are not practical; silicon has a poor debugging ability, and manual prototyping cannot handle large designs. The practical benefits of CAP are discussed.<>
