When implementing an ASIC design on an FPGA prototype, it is often the case that the original ASIC design uses DesignWare® Foundation components, which are not readily available for an FPGA implementation.
ZW-FPGA is a product that offers RTL source code for the most commonly used DesignWare™ Foundation Library components, which has been tested to synthesize properly for the most widely used FPGA Synthesis tools: Synplify® Pro and Xilinx ISE™ XST.
It is compatible with a wide variety of off-the-shelf and custom FPGA prototype boards.
