Automating ModelSim

hi!

you can try to modify the *.do file into /simulation/modelsim directory; if you google "modelsim command reference" there are some pdf that explain commands (sorry I can't post link, I'm a newbie:))

Hi,

Dofiles are TCL scripts. In VHDL, using GENERICs at the top level of your TB, you can then change parameters through the TCL script.

I tend to not rely on waveforms, but assertions within the testbench (self checking testbench). So I run iterations of the simulation, using generics to modify the simulation characteristics.

Unfortunately I cannot help with NativeLink... but I'll look that up.

Here's a snippet from a dofile I wrote a while back.

prbs_tester_tb is the testbench.

This runs 4 simulations, changing the PRBS files and UUT characteristics each time.

puts "******************************************************************"

puts "Running the NNNNN simulation"

puts "******************************************************************"

vsim -gPATTERN_IN=O"1" -gLFSR_SEL=X"F" -gSTIM_FILE="./stim/lfsr_F__trib10.dat" -gTRIB_IN=X"10" prbs_tester_tb

run 4 ms

vsim -gPATTERN_IN=O"1" -gLFSR_SEL=X"D" -gSTIM_FILE="./stim/lfsr_D__trib12.dat" -gTRIB_IN=X"12" prbs_tester_tb

run 4 ms

vsim -gPATTERN_IN=O"1" -gLFSR_SEL=X"C" -gSTIM_FILE="./stim/lfsr_C__trib03.dat" -gTRIB_IN=X"03" prbs_tester_tb

run 4 ms

vsim -gPATTERN_IN=O"1" -gLFSR_SEL=X"E" -gSTIM_FILE="./stim/lfsr_E__trib71.dat" -gTRIB_IN=X"71" prbs_tester_tb

run 4 ms

i normally use NativeLink to generate the ModelSim .do file initially. then i edit the generated .do file to add internal signals and/or change the radix

you can then tell Quartus to use the edited .do file instead of generating a new one every time Tools > EDA Simulation > RTL Simulation is run. you can do this in the NativeLink setup by choosing the Script to compile test bench instead of Compile test bench radio button

the downside is you will have to edit the script directly to add/remove any HDL source files to the ModelSim compilation, or else re-run the normal NativeLink flow and copy+paste your additions to the newly generated script

Thank you for your answer.

I solved the problem starting from your suggestion and making a sligth change.

Step 1)

I run a first simulation.

2)

I copied the .do file in the directory modelsim/simulation in another .do file with MySim.do name

3)

I added the necessary commands in the MySim.do file.

4)

I set the Simulation settings enabling the "Compile test bench" radio butto and checking the "Use script to set up simulation" checkbox.

I also inidcated the simulationMySim.do file as the script to set the simulation.

In this way the simulation directly comes out as required and reflects all the changes in the testbench.

Further,

if I want to run the simulation again without restarting ModelSim,

I simply run the "do MySim.do" command in the "ModelSim -> Transcript " window.

Hello,

could you tell me how i can add internal signals to modelsim by editing .do file?

Which command?

Thank you very much

if you add signals in the GUI, the equivalent command to add to the .do will be in the transcript window

paste it into the .do file after the existing add wave command

I do like this. In my case the signal is named clk_Contr and is in the hierarchy Ptot_tb/UUT/MI/:

add wave {sim:/Ptot_tb/UUT/M1/clk_Contr}
