ModelSim 10.3d Create/Edit Waveform

I am having problems creating a waveform in ModelSim Altera SE 10.3d. 

 

I am trying to follow the tutorial "Getting Started with Quartus II Simulation Using the 

ModelSim-Altera Software" but I am unable to create the clock waveform. Instead of 

the green clock waveform shown in figure 1-5, the waveform windows shows a broken 

red line. 

 

Configuration: 

* Windows 7 64-bit 

* Quartus II V15.0.0.145 Web Edition 

* Qaurtus II V15.0.1.150 Patch 

* ModelSim SE 10.3d 

 

Steps Followed: 

* In Quartus II select "Start Analysis and Elaboration" 

* From "Tools" select "Run RTL Simulation" 

* In ModelSim window select "Counter" under "Work" 

* Right click and select "Create Wave" 

* Right click on "/counter/clk" and select "Create/Modify Waveform" 

* In the "Create Patter Wizard" select Clock 

* A broken red line is shown instead of a green clock signal.

Hi, 

 

Just wonder if you could workaround by generating the clock waveform by coding it in the test bench? I have not tried the steps in the tutorial but generally I will use test bench for clock generation.

Hi bruce, 

 

You need to run the simulation e.g. run 1000ns in order to see the effect.

Are you seeing the same as the attached screen shot? I'm facing the same behavior but the simulation is running correctly. Seems no setting can be changed and I think this might be a bug. Like suggested by other user, running the simulation using testbench.
