I have a problem with Xpedition FPGA I/O Optimizer in VX 2.4. I have added a FPGA in Xpedition Central Library through FPGA Wizard. The FPGA is added in the Xpedition designer schematic but I am not able to open the FPGA by doing Tools = FPGA I/O Optimizer. It ask me to create a new FPGA part or provide fcd file. How can I get fcd file for the existing schematic design having FPGA ?
