Hi Randy The options used in mapping, place and route etc are found in fast_runtime.opt in the etc folder in the XPS_IBOB_base folder containing the EDK project created by the CASPER toolflow. You will find a bunch of options that you can play with here. Save the changes and then re-run the EDK/ISE/Bitgen step to run the ISE tools with the new options. I found that the existing options were quite well optimised for timing. The Xilinx documentation will provide info on the options to play with.
Good luck Andrew 2008/10/1 Randy McCullough <[email protected]> > All, > > When reviewing the timing report of a failed build, the "Timing Improvement > Wizard" > nearly always suggests emphasizing TIMING over PLACEMENT using the "-t" > option. > > Has anyone tried this?
