Hi guys, need a little bit help. I try ModelSim ALTERA STARTER EDITION 6.5b for the first time, have created a test project (two inputs, two outputs) and wanted to simulate it. My problem is – I can add my signals to the wave window, but I did not find a way to add a waveform to my signals in this window. I have used ModelSim SE PLUS before and in this program if I clicked with the right mouse button in the Objects window, I have got in the pull-up menu (upon other items) the “create wave” item. In the ModelSim Altera Starter Edition I see all these items too, except the “create wave” item. How can I add a waveform here? Thank you

You have to drive signals from a testbench.

Tricky, thank you for your prompt answer. Is it a extra limitation of ModelSim Altera Edition, that I have to obligatory use testbench and cannot add a waveform “on the fly” in the wave window?

I would recommend using a testbench to drive the inputs and to test the response of the outputs, but you could use the modelsim force command to drive your inputs.

I'm having the same problem described by the original post in this thread. I'm following the tutorial in Altera's ModelSim_GUI_Introduction.pdf and cannot access the "create wave" menu selection. How do I create a testbench?

i think the Waveform Editor was only enabled in the latest ModelSim-A(S)E included with ACDS 10.1, version 6.6c

You cannot compile test benches with quartus. Quartus only understands the "wait until" command for synthesising code. Test benches cannot be synthesised.

Secondly, do not use std_logic_arith and numeric_std in the same file.

Tricky, thanks for your information about Quartus.
You are right, it is not a good idea to use std_logic_arith and numeric_std together (have overlooked it as I copied parts of two different designs)

no, i don't think so

try Quartus II 10.1 and ModelSim 6.6c

Hello, I continue with this topic while my question is the same.

How can I use the waveforme editor with modelsim 6.6d ? I've tryed with the example (counter.v) but I cannot change the waves.

Hello all,

I am new to this software and trying to learn in my free time.

Can anyone tell me how to setup modelsim on Quartus -II? I have tried to follow the steps from the pdf file provided,but I cannot see the option of settings in bold under Assignment.

Is there any way I can open Modesim once I download Quartus-II?

Thanks

Thanks all.

I finally figured it out to open Modelsim.
