GENERAL DESCRIPTION: When customer edits a CLB then tries to save changes, the following error occurs:
Dr. Watson An application error has occurred And an application error log is being generated. fpga_editor.exe Exception: access vioation (0xc0000005), Address: 0x003652e0
A core dump will happen on the workstation.
Solution
This problem seems to be related to the 'superbells' in the design - either through changes in the NCD file (through FPGA Editor) or through the creation of hard-macros.
These superbells introduce problems when the timing is analyzed in a design, and can cause FPGA Editor to crash. The current work-around for this problem is to not use the .pcf file when FPGA Editor is loaded.
This can be done by going into the appropriate version/revision directory, and renaming the .pcf. Then launch FPGA Editor, make the changes, and save the design.
