Re: Running ModelSim in command-line mode

Altera_Forum · ‎03-09-2013

Hi,

I write a testbench name test_FA.v. In the comman prompt, i go to test_FA.v directory and taip

1) vlib work

2) vlog test_FA.v.

3) vsim -c -do FA_run_msim_rtl_verilog.do FA -wlf waveform.wlf

However, I cannot see waveform.wlf created in the directory.Can anyone help me?

Perform the same sequence in the Modelsim GUI first. You might have a problem.

For example, although you create a work library, you do not map it, eg.,

1) vlib work

2) vmap work work

or

vmap work [pwd]/work

If modelsim.ini already has a work mapping and it does not exist then you will see an error message.

Also, I'm not sure that you have the names correct, eg., (2) has test_FA but (3) has FA, perhaps this is supposed to be test_FA?

Cheers,

Dave

Sorry ,i taip wrong, act all is FA. Now i follow steps below but still cannot get the waveform.

1) vlib work

2) vmap work work

3) vlog FA.v.

4) vsim -c -do FA_run_msim_rtl_verilog.do FA -wlf waveform.wlf

The contain of FA_run_msim_rtl_verilog.do as below:

transcript on

if {[file exists rtl_work]} {

vdel -lib rtl_work -all

}

vlib rtl_work

vmap work rtl_work

vlog -vlog01compat -work work +incdir+C:/altera/11.0/quartus/chapter2/exam2_3 {C:/altera/11.0/quartus/chapter2/exam2_3/FA.v}

I still have 1 question, if i taip vsim -c in command prompt, the command prompt will become

Modelsim>

when i taip "wave create -pattern none -portmode input -language vlog /FA/cin" it shows "wave create not supported in batch mode" can I write the script as in modelsim GUI ?

In the modelsim gui, simply type

Modelsim> vlib rtl_work

Modelsim> vmap work rtl_work

Modelsim> vlog FA.v

Modelsim> vsim FA

Modelsim> add wave *

Modelsim> run 10 us

Your FA.v design should be a testbench, i.e., something that provides stimulus to a component. Normally you would have FA.v and FA_tb.v, where FA_tb.v instantiates the component in FA.v

yes,i got no problem when running in GUI, but how can i simulate the same thing in windows command prompt?

Altera_Forum · ‎03-11-2013

Put the same commands in a Tcl script, and run it.

Though it makes no sense to create a waveform when using the command-line. For command-line mode, you typically run the testbench and check the exit code for pass/fail, then run the GUI for interactive debugging of the issue.
