FPGA Editor 2.1i: When routing Probes, It appears to freeze, Not Responding, takes a long time
Keywords: fpga editor, crash, freeze, not responding, long time
Problem Description: When I am trying to set a probe in FPGA Editor, my display appears to freeze. WinNT's task manager says "Not Responding". This continues after the probe window comes back from the probe selection screen. You are unable to select anything in the window. Why?
This most often occurs in Virtex and very full designs that use a PCF file. The program has not frozen, it just takes a long time. If you let it sit for a while (depending on the speed and memory of computer), the window will come back with the correct probe routed to the pin.
Workaround: Remove the PCF file from the directory to another, or do not specify a PCF file when opening FPGA Editor. The PCF causes the Editor to route based upon the timing and physical constraints for the design .
