Inside the Transcript window you could see something like that: In the Design Units input you have now: badprog.hellosim. Open the badprog design (with a "+" before) > select hellosim.v. The Start Simulation window has appeared. Simulatingįrom ModelSim > Simulate > Start Simulation. If there were an error, a red cross will appear. If all was correct, you should have a green tick instead of the blue question mark. Right click hellosim.v and select > Compile Selected.

To see the file itself, double click it, the code will appear on the right. It means that the file hasn't been validated yet. > select the hellosim.v file from your own project > OK.Ī blue question mark has appeared in the Status column in front of your file. So let's import the hellosim.v file from our project.įrom ModelSim, in the Library window, there are, at bottom, two tabs.Ĭlick Project, then right click on the white pan to open a window menu > Add to Project > Existing File. Notice that if we had several files, we would have to import them all. Let's say this project is called HelloSim and the file inside is hellosim.v (yes it's a Verilog file, but any HDL will be correct). Oh, of course, you've to create a project in an HDL, such as Verilog for example. OK, now we've to import existing files into project.

The timing simulation is checked only if the functional is correct.Īnother difference between functional and timing simulation is that the first is fast, the second is sure.īut to have a great design circuit both are necessary of course. In general, the functional simulation is made first. That's exactly as if you looked on a real device. The timing simulation is different because it adds a notion of time. That's how electrons could pass through the circuit. The functional simulation checks only if wires and gates seem correct in order to say if the circuit's design could be validated.Īctually it checks how the circuit behaves after applying inputs. There are two different types of simulation: You could use it with any HDL such as VHDL, Verilog or SystemVerilog. To be honest a simulation tool is really complex to handle, so this tutorial will be most an introduction than exhaustive examples. This is what we're going to see in this ModelSim-Altera Starter Edition introduction.

If you've not done any of your own code to trigger this and you're just trying to launch the application, contact the vendor and file a support request.After installing ModelSim-Altera Starter Edition, what's better than testing it?

But it might be all wrapped up in some sort of abstract widget management code too it's not trivial to hunt this down unless you're lucky. I'd guess it would in turn be done with list, a widget name, etc. At a guess, it's the empty value that is passed in from the menu callback identified as: ::Vsimmenu:efaultMenuPostCmd. If cid is unexpectedly empty, you're going to be tracing it back. Check particularly if you need to say global _clients or variable _client or something like that (maybe involving upvar). The only way to work out whether _clients is right is to look at the code (which you've not shown us). In particular, we see that you were trying to read from a variable that didn't exist that means that either the _clients array isn't what you think it is, or that cid is an empty string when you don't expect it to be. You need to be a bit inventive to figure out what it means, and why the problem might be occurring. OK, you're looking at a Tcl stack trace thrown by an event callback.
