Modelsim command line: How to pass a generic parameter for my testbench ?

Hello all,

That's my first post ..

I have a testbench.vhd having the following entity:

Entity TestBench is 
Generic(Mode          :integer:=64); -- valid values are 64/128
End TestBench;

Additionally, I wrote a file.do that compiles everything and run the testbench from the command line <linux>:

vsim -c -do file.do

The file.do looks like:

onerror { exit }
exec rm -fr Project/;
exec mkdir Project
cd Project;
vlib work;
vcom ./../*.vhd;
vsim -novopt -quiet work.testbench;
run -all;
quit -sim;
exit;

Is there a way to pass the generic parameter "Mode" from the command line?

Thanks in advance,
Tarek

Vsim command use -g<genericname>=<value>

vsim -gMode=64 -c -do file.do

Furthermore, can I specify more options to check for it in the file.do
as:
vsim -gMode=64 -c -<more options> showme -do file.do

and in the file.do:

if [showme]
{add signals to wave, and view it}

Or I'm just daydreaming ?

Thanks in advance,
Tarek

OOps ! Sorry, but it did not work!!

Adding the "-GMode=128" to the command line call did not work.

But it worked when added to the file.do

ie: The file.do looks now like:

onerror { exit }
exec rm -fr Project/;
exec mkdir Project
cd Project;
vlib work;
vcom ./../*.vhd;
vsim -novopt -quiet -GMode=128 work.testbench;
run -all;
quit -sim;
exit;

but I want to pass the generic from the command terminal, not by editing the file.do itself.

Can this be done ?

For Allah's sake and the community,

I found the solution

in the linux terminal:

vsim -c -GMode=128 -do file.do

and in the file.do, you have to check the $argv

set x [lsearch $argv -GMode=128 ];
if "$x != -1" { 
set Mode 128;
}
if "$x == -1" { ## Default Mode 
set Mode 64;
}
..
..
vsim -novopt -quiet -GMode=$Mode work.testbench;
