XDL-Based Module Generators for Rapid FPGA Design Implementation

XDLCoreGen is described, a module generator framework which directly generates placed and routed hard macros in XDL. XDLCoreGen is intended to be used in a rapid prototyping flow such as HM Flow, which achieves short FPGA implementation times by bypassing the conventional Xilinx tool flow and directly assembling designs from pre-built hard macros. The structure of XDLCoreGen is described and its unique cache-based router is highlighted as a key component to achieving extremely fast module generation times. Testing results are provided to demonstrate XDLCoreGen´s ability to generate fully placed and routed hard macros in milliseconds.
