You’ll end up with a work-obj You can always select more in gtkwave to display more information. And yes getting the source for the two VHDL files from the ‘tutorial’ was painful. I’m planning to develop a A hgdl file can be clicked on and gtkwave has a set of rules used to search for the applicable gtkw file. When I compiled them together, that is.
That as they say is a big ask! The first one is a VHDL hello world program, the second one is a one bit adder with a test bench. Once this version of ghdl is installed, in a terminal you can info ghdl Scroll down to Starting with GHDL, hitting carriage return.
Can someone tell how exactly I can test a vhdl program on my Mac? I didn’t do it. Ghdp possible with binary releases of ghdl and gtkwave to separate user from developer.

Then I run ghdl -a myfile. There’s also development toward using ghdl as an llvm front end as well as a purely interpretive version to supplant ghdl-mcode.
Obtaining Tony Bybell’s gtkwave gtkwave. Still, my vhdl code compiled. The original poster asked for some real examples with command line values. The model quits executing after the last signal event so no stop time need be passed to the run command e. You might also note the assignment of ‘X’ to Cin at 60 ns in the gtkwave display, I did it to show the last values assigned in the testbench.
And a check shows ghdp the gtkwave. First, you have to compile the maanual this is called analysis of a design file in VHDL terms. VHDL will only stop executing when either ther are no more scheduled signal updates or execution time maxes out.
In an mnual version of ghdl the -r run command also elaborates. You should also limit the run time duration with a guard timer should your test bench provide a free running clock.
As an oversight I didn’t think to amend the ghdl manual to include the word mcode wherever Windows appeared and release modified manual.
The resolution isn’t so good and it’s Linux centric. Email Required, but never shown.
Then I manial ghdl -e myfilewhich does nothing. The latest version of the application can be downloaded from this link on Sourceforge – gtkwave.
