Earlier in this group someone discussed "dynamically" programming an FPGA to achive a "hardware router" under software controll. I am currently working with Xilinx Spartan series FPGA's that are under control of a RTLinux application. Does anyone know how to encode (pack bits) of the spartan CLB's. I assume you can take a working bitstream for a device, and alter a small portion of it to change one CLB's function (including updating the bit checks and CRC's.
