Hi,

How can I use an environment variable in a ".do" script running it in
the modelsim window?

I tried the windows environment variable in % characters, but doesnt
work. Absolute paths work but I want use this scripts on different
computers.

vsim -sdftyp {/UUT=%MYDIR%/dir/.../timesim.sdf} ...

Thanks

Try using the Tcl env() function. Modelsim's shell is essentially a
Tcl command line evironment and the .do files are .tcl scripts.

to get your directory, try /UUT=env(MYDIR)/ .....

I don't have a Modelsim installation handy so this is just off the top
of my head. Hope you find the solution!

MJB forgot the variable sign,

vsim -sdftyp /UUT=$env(MYDIR)...
