#MODELSIM 10 COMMAND WINDOWS#

One day if you work for a company that cares you can have multiple licences and thus multiple Model-Sim windows running at once

ModelSim won’t open! You can only have one instance of ModelSim open at a time on the university license.

Make sure the path to ModelSim-Altera is valid on your machine! Example path: C:/altera/10.0/modelsim_ase/win32aloem

#MODELSIM 10 COMMAND SOFTWARE#

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 10 COMMAND CODE#

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 gVAL="\"a b c d\"" # Added additional quotes w/ escaped quotes It suggests wrapping the whole -g command in curly braces # Suggested by ref.

#MODELSIM 10 COMMAND MANUAL#

423 of the ModelSim 10.5 Command Reference Manual (Sorry, couldn't find one for 10.7 off-hand) has notes about limitations of using -g. What it really needs is to assign "a b c d" (including quotes) to VAL, the same way you showed in pure VHDL. This means the value it received is what is in quotes, meaning it is trying to assign just a b c d to VAL. The warning put quotes around a b c d like "a b c d" and around VAL like "VAL". Based on your error message, it looks like spaces aren't the issue, but actually the quotes themselves are not being included in the value being passed to the generic, and need to be escaped.
