When synthesizing a VHDL design using the Metamor XVHDL compiler on Windows 95, you may get the following windows error:
"This operation has performed illegal operation and will shut down."
When you click on the DETAILS button, it says "XVHDL caused an invalid page fault in module XVHDL.EXE at ___"
This problem can be caused by having long instance names in your code. A workaround is to try to reduce the instance names to less than 7 characters. Additionally, if the instance names contain special characters including "_", try not using them.
