Removing temp files (VSOUT)

The VSOUT temp file is the communication mechanism between the simulator kernel and the ModelSim GUI. In normal circumstances the file is deleted when the simulator exits. If ModelSim crashes, however, the temp file must be deleted manually. Specifying the location of the temp file with TMPDIR (above) will help you locate and remove the file.

Note: There is one environment variable, MODEL_TECH, that you cannot - and should not - set. MODEL_TECH is a special variable set by Model Technology software. Its value is the name of the directory from which the vcom compiler or vsim simulator was invoked. MODEL_TECH is used by the other Model Technology tools to find the libraries.
