OpenFPGA Physical- Directory Structure

Creating Tapeout Project

The hierarchical flow of the OpenFPGA-Physical recommends incrementally building the large FPGA fabric. In that methodology, the larger fabric such as a 100x100 FPGA design can be derived from a smaller replica 4x4. The OpenFPGA-Tapeout directory is designed to support such a design hierarchy
