Nativelink Error: “Can’t launch the ModelSim-Altera software - the path to the location of the executables for the ModelSim- Altera software were not specified or the executables were not found at specified path”.

Double check that you have applied the changes that you made with the testbench setup.

Then click Tools > Run EDA Simulation Tools > EDA RTL Simulation

Set your module as the top level module, compile.

testbench)Īdd the file containing your testbench module. Select Compile testbench: name of the top level module (e.g.

Assignments > Settings > EDA Tool Settings > Simulationįormat for output netlist: The language you wrote the testbench in.

I like to put in some form of index that correlates with clock ticks.

Modelsim can only simulate modules that you have the verilog files for.

M4K blocks are simulated as having registered outputs.

Create inputs for the device under test (DUT), usually reset, play, input(s), output(s), etc.

Since testbenches are usually not synthesized, you can use initial blocks. Note you can never have a resolution that is lower than the length of the tick though

If you want to speed up your simulation, make the resolution lower.

Because of `timescale 1ns/ 1ps, max precision of 1ps, or.

Because of `timescale 1ns /1ps, #22 will be translated to 22 ns.

timescale indicates what the length of a “tick” is and the resolution of “ticks”.

Some key components of a testbench module:.

Step 1: Write a Testbench in Verilog/VHDL I have tried to only include what is useful. If you want more tips and tricks read the additional comments. The main points are underlined and numbered. This is a quick and dirty guide to getting modelsim working with Quartus.

Modelsim is a powerful tool used to simulate Verilog or VHDL code that you have written. The Quick and Dirty Guide to Using ModelSim with Quartus - Julie Wang 2014

If you are using this switch to preserve visibility for Debug or PLI features, please see the User's Manual section on Preserving Object Visibility with vopt. This will cause your simulation to run very slowly. # ** Error (suppressible): (vcom-12110) All optimizations are disabled because the -novopt option is in effect. # Model Technology ModelSim SE-64 vcom 10.7 Compiler 2017.12 Dec 7 2017 Run 2 if I change VoptFlow to 0 I get an error when runing: Vcom -O0 -work work $QSRC_DIR/HwSrc/UT_DP_PreProc.vhdĪdd wave -noupdate -group DP_C sim:/compactor_tb/CompactorDUT/CompBasic/DP_C/* Vcom -O0 -work work $QSRC_DIR/HwSrc/UT_DataProcessing.vhd Vcom -O0 -work work $QSRC_DIR/HwSrc/UTDataProcSimTop.vhd Vcom -work work $QPRJ_DIR/TestBenchs/UTDPtestBench.vhd Source $QSYS_SIMDIR/mentor/msim_setup.tcl Thanks, set QPRJ_DIR D:/LHCb/FPGAPrjs/UTDataProcV01 So, what I'm doing wrong? what would be the correct set of options in order that Modelsim shows all signals including the ones for debug? I attach the simScript.do where now is the -O0 option I'v tried multiple options from vopt but without success.

I'm simulating with modelsim 10.7 a design created with Quartus Prime Pro 18, but I don't know hot to do the simulation with no optimizations with this new version.
