Environment variables

ModelSim EE/PLUS Reference Manual Compilation and Simulation

Setting and using environment variables in Windows

Set the environment variable from either the DOS prompt or by editing the

autoexec.bat

file.

Set the variable from the DOS prompt (note that \temp\work is a valid Model

Sim

library):

set MY_PATH=\temp\work

Add this line to the

autoexec.bat

set MY_PATH=\temp\work

MODEL_TECH_TCL used by VSIM to find Tcl libraries for: Tcl/Tk 8.0, Tix, and VSIM; defaults

to <install_dir>/../tcl; may be set to an alternate path

MGC_LOCATION_MAP used by Model

Sim

tools to find source files based on easily reallocated

"soft" paths; optional; see: "Using location mapping" (p539); also see the

Tcl variables: SourceDir (p254), and SourceMap (p254)

MTI_TF_LIMIT limits the size of the temporary transcript file; the value of the variable is

the size of k-bytes; TMPDIR (below) controls the location of this file;

default = 10, 0 = no limit

PLIOBJS used by VSIM as an optional method of loading PLI object files; consists

of a space-separated list of file or path names; optional

STDOUT allows you to specify the path and filename of a temporary file containing

all stdout from the simulation kernel; the file will not be deleted when the

simulator exits

TMPDIR used by VSIM for creating temporary files; consists of a path to a

tempnam() generated file (in a temporary directory) containing all stdout

from the simulation kernel; optional

MODELSIM used by all Model

Sim

tools to find the modelsim.ini file; consists of a path

including the file name; optional; see: "Location of the modelsim.ini file"

(p414)

MODELSIM_TCL used by VSIM to look for an optional graphical preference file; see:

"Simulator preference variables" (p210)
