While this is meant to mean full support, there certainly are still many issues present. The focus was probably to support language features already supported in synthesis.

I personally tested support for VHDL-2008 fixed point number libraries, which require generic packages.

Vivado 2023.1…[Read more]

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).

Two tests I tried (AXI4Lite, UART) failed with what seems to be GHDL failures rather early into the build process (before simulation). Am I doing something wrong? Is this a known issue? Is there a combination of GHDL/OSVVM release tags, which…[Read more]
