How do I make a testbench in ModelSim?

How do I make a testbench in ModelSim?

Go to Simulate, click Start Simulation. At the Design tab, search for work, then expand the work and select your testbench file. At the Libraries tab, click Add.

How do you make a testbench?

Verilog Testbench Example

  1. Create a Testbench Module. The first thing we do in the testbench is declare an empty module to write our testbench code in.
  2. Instantiate the DUT.
  3. Generate the Clock and Reset.
  4. Write the Stimulus.

How do I create a new folder in ModelSim?

To compile the source files in the ModelSim environment, you must create a working directory or map an existing working directory: File > New > Library or File > Import > Library or type ‘vlib work’ in the command line window. a new project under a new working library, such as ‘final_proj’.

How do you simulate waveform in ModelSim?

Display the waveforms after loading the testbench and before running the simulation. To display waveforms, select the design under test (inc) in the “sim” tab, right-click the mouse, and select “Add > To Wave >All items in region”. Alternately, bring up a wave window by selecting “View > Wave” in the ModelSim menu.

How do you make a Quartb testbench?

You can get Quartus to produce a shell testbench file by selecting Processing | Start | Start Test Bench Template Writer. There will now be a file in your simulation\modelsim directory. Open it. The section near the bottom of the file is where you put statements for your simulation.

How do I specify an EDA simulation tool?

On the Assignments menu, click EDA Tool Settings to open the Settings dialog box and then click Simulation.

  1. Verify that ModelSim*-Altera® software or any third-party tools are selected in the Tool name field.
  2. Under NativeLink Settings, make sure the correct test bench is selected.

What is testbench code?

A testbench is simply a Verilog module. But it is different from the Verilog code we write for a DUT. Since the DUT’s Verilog code is what we use for planning our hardware, it must be synthesizable. Whereas, a testbench module need not be synthesizable.

How do I add a Unisim library to ModelSim?

3 Answers

  1. compile UNISIM libraries by runnin compxlib and following wizard.
  2. then in your modelsim, library pane add new library.
  3. after that add library from existing library and point to folder which contains compiled version of unisim, e.g. it is C:\Xilinx\10.1\ISE\vhdl\mti_senisim for me.

How do I export a waveform from ModelSim?

To save the current format of your Wave window, click in the Wave window so it becomes the active window, then choose File -> Save. The Save Format dialog box will appear. Browse to a directory that makes sense (i.e. your project directory) and save the . do file.
