Found it!

Apparently the mcode version of GHDL errors out if you subtract 1 from an uninitialized integer.
All other simulators are ok with this. OTOH, it was easy enough to fix. So there is
now a fix in the 2021.07 release. It is on GitHub now. It will be on OSVVM.org
shortly

Thanks Jim. I appreciate the information. Initially I only need RandomPkg so I’ll try to compile the files myself.

Best regards, Edward

Are you running Ubuntu with the GCC build? Try either the mcode or lvvm. Unai setup CI for OSVVM. Prior to this I was testing OSVVM only on Windows 10 with 64 bit llvm. In testing we found that Ubuntu with GCC is not working for some items. I have not looked at the bugs, however, since it works for Ubuntu with mcode and lvvm and widows…[Read more]

WRT OSVVM and xsim/Vivado. Here is the current update (July 2021):
I compiled all files on 2021.1. That was momentary good news. However, some packages do not work yet in simulation. In particular, AlertLogPkg. It needs a deep dive into root cause like I did for the AXI verification components in GHDL. It worked well in GHDL since I could find one…[Read more]

Hi,

I was able to get the Axi4 and Axi4-Stream tests to work.
The above log also list the UART test, which is still failing (I checked again today).


ghdl --elab-run ended with error ghdl:error: overflow detected

I should also note that the Virtual Transaction Interfaces (VC with suffix of Vti) use external names and GHDL does not support external names.

This is currently what I am running in the OSVVM libraries for regression:

build ../OsvvmLibraries

# Run Tests
build ../OsvvmLibraries/UART/RunAllTests.pro
build ../OsvvmLibraries/AXI4/AxiStream/RunAllTests.pro
build ../OsvvmLibraries/AXI4/Axi4/RunAllTests.pro
# Next one has failures in running tests

I am running GHDL version: GHDL 2.0.0-dev (1.0.0.r292.g3807826b) [Dunoon edition]
This is from one of the nightly builds. All of 2021.06 compiles. All of 2021.06 simulates except Axi4Lite – Axi4 Full was updated to work with GHDL – so you can use that instead. The Axi4Lite updates will be coming later this year.
