I'm having problems with the TCL commands in ModelSim SE - Altera Version. (I'm running ModelSim ALTERA STARTER EDITION 10.0c) It seems like many of the commands that should work... do not. For example just trying to run one of the included examples fails:# Error in macro C:\altera\11.1\modelsim_ase\examples\gui\addmenu\addmenu.do line 27# invalid command name "add_menu"# while executing# "add_menu $wname mine"# (procedure "AddMyMenus" line 9)# invoked from within# "AddMyMenus $wname" Trying to use some of the commands listed here: www.cs.pitt.edu/~don/coe1502/Reference/vsim_quickref.pdf ...like .wave.tree zoomfull doesn't work. Commands like winfo also fail. Basically I'm trying to learn how to do introspection on the GUI elements, in order to generate new Tk windows, similar to what has been done here: www.doulos.com/knowhow/tcltk/examples/constellation/mti_tcl.pdf ...but I keep hitting roadblock after roadblock since the commands don't seem to be working. Any ideas? Thanks!

Ah, okay. I was starting to come to that conclusion, but none of the documentation mentioned this. Thanks Dave. I'm curious if there is a way to enumerate all of the signals that are currently in the Wave window just using TCL? As a real kludge I think I can save the wave format using the following: write format wave -window .main_pane.wave.interior.cs.body.pw.wf {C:/wave.do} Then I can parse the output to find all the signals, but I would hope there is an easier way...? (I'm trying to put together a generic TCL script which will find all of the signals I've manually added to the wave window, add those to a list then export it to a tabular file, for use in Python.)

Since you're using it to populate the wave window, why can't you just have the python use the .do file directly. For example, when I use Modelsim, I just create a Tcl procedure with the same name as the testbench, and inside that procedure call vsim and populate the wave window using the .do file. Cheers, Dave

Sorry, I should be a little more clear on my intent. I'm trying to export all the wave signal's simulated data, not just the list of signals names to Python. The only way I've found to do this is to first export the wave data to the List window, then Export it as Tabular data. So, I'm trying to put together a generic TCL script that will automatically export whatever simulated data is in my Wave window to a file for import in Python. Seemingly I have to push all the data to the List window first, then I can export it. (Perhaps there is a better way?)

--- Quote Start --- Perhaps there is a better way? --- Quote End --- What is the "Big Picture" here? Why do you want the data in Python? You could format the data directly in SystemVerilog or VHDL and write the data files in exactly the format you want. The HDL languages are just as capable as any other programming language. For example, I'll sometimes have the testbench write a MATLAB script, and then I can generate plots without having to actually write MATLAB code :) Cheers, Dave

Learning to push the data out via SystemVerilog would pay dividends in the long run.

Since you work with a bunch of ASIC guys, you probably have some proficient coders that can help you.

That being said, feel free to waste time learning Tcl, its not that bad :)

See this thread for some Tk GUI elements that'll work in Modelsim-SE, Quartus II, ActiveState ActiveTcl, etc:

True, time to pick their brain.

But Dave, everything is a string in Tcl, and there is no OOP as far as I can tell :eek:. (But in all seriousness, Tcl is used so much I better bite the bullet and pick it up anyway.)

Edit:
Thanks for the link.

Yep, that is the conclusion I came to as well.

The key is to use it where appropriate. Its decent enough for automating the build tools, and its mediocre for building GUIs. I don't use it for anything more complex than that.

Cheers,
Dave

PS. OOP in Tcl is [incr Tcl]
