10.1 ISim - ERROR:Simulator:608 - Unable to remove old copy of testbench_isim_beh.exe

Description

When I attempt to run an ISim simulation, I receive the following error:

ERROR:Simulator:608 - Unable to remove old copy of testbench_isim_beh.exe

How can I resolve this issue?

Solution

This happens if for some reason the previous simulation was not closed.

For example:

On an NT machine, consider simulating a design called counter.vhd

fuse -vhdl counter.vhd

x.exe

X.exe is the executable created by fuse which is run for simulation, and this process at rare occasions seems to run even after closing the application. Therefore, please open the task manager and end the x.exe process.

NOTE: Please note - x.exe is an example. The executable is usually named after the testbench.
