But if you are using precompiled UVM it may be compiled with other timescale depending on compilation option used when it was compiled or tools default timescale value (uvm does not set timescale int the code).
In this case for us precompiled UVM timescale is 1ps/1ps - so UVM gets 1000000000 in set timeout but interprets it as ps. As a result timeout is 1000 times smaller that you expect. That is why we are getting timeouts.
It is hard to find perfect solution. One of them is to recompile the UVM with -timescale 1ns/ps (or whatever you will use for your design).
Our hjson-based logic for constructing VCS commands always passes
-elfile, but this doesn't work if the following list of arguments is
empty.
It seems difficult to figure out how to teach dvsim.py to do something
like "prepend X to Y if Y is nonempty", so let's just add an empty
file for now.
The previous code correctly dumped to "waves.fsdb" if you had Verdi
installed. Unfortunately, it dumped to the same file name if you
didn't, which was rather confusing.
This patch passes a "DUMP_BASE" environment variable, rather than
"DUMP_FILE", which doesn't include the extension. Then it appends the
correct extension at runtime in the TCL, when we tell VCS what sort of
dumping to do.
The code now also checks for all environment variables before reading
them, allowing defaults if they don't exist. The defaults might not be
what you want, but a syntax error at this point causes VCS to sit
waiting for terminal input (with no stdin!), which is kind of annoying.
I've also removed the copy-pasted Verdi documentation. Apart from
anything else, this is probably copyright, so we shouldn't have a copy
in the repo!
