Mind boggling indeed and very stressful as I have some deadlines to meet. The output sine wave of the modulator will be the direct input carrier or the inverted (180° phase shifted) input carrier, which is a function of the data signal. Mod4_counter mod4_cnt(clk, reset, start_count, count_value) Īs you can see in the screenshot, the signals have been added on the wave window and run icon clicked.

Pre_count_value <= pre_count_value + 1'b1 Module mod4_counter(clk, reset, start_count, count_value) Modelsim was installed only 3 weeks back and I don't think there is anything to do with licensing because I tried uninstalling modelsim, reinstalling and repeating the same process but again that was to no effect. format, output file format and simulation scenario of QUCS, LTspice IV and eSim. I have enclosed a screenshot of my wave window. simulating a half wave rectifier circuit design in different EDA tools. This procedure worked yesterday and is not working today. Here is a checklist of the procedure I followed.Ģ) I added counter.v and counter_tb.v to a project.ģ) I clicked "Start simulation" in the "Simulate menu"Ĥ) The I clicked my testbench module name under the work directory.ĥ) Then I clicked on the "Objects" tab and selected all the signals, right clicked, wave, add to wave all the signals in the design.Ħ) Now when I move to wave tab and click run icon i don't see any of the green waveforms. Ive attempted various output levels and frequencies of the square wave. It shows the voltage on the DC-blocking capacitor - it gets charged and starts output a stabilized AC signal, but unfortunately, it failed to show any voltage from the output side. Analysis with Octave Starting GNU Octave and issuing the following commands dataloadQucsDataSet(’temp.dat’) loglog(data(1).data, data(3).data) produces a log-log plot of the output voltage versus the frequency. But today morning after I rebooted my laptop and tried opening modelsim and repeating the same process, I am not able to see any waveform on the wave window. To investigate the behavior of the amplifier, I feed a 100 mV square wave at the input. Yesterday the simulation worked and I was able to see the waves in the modelsim wave window after adding the signals to the wave. I tried simulating a simple counter in modelsim pe student edition 10.0a.

I have a perplexing problem and its very irritating.
