Hi  
I am creating some test benches for a client they want to use UVVM with GHDL. I grabbed the latest releases of both. But have some issues compiling the UART example design.

How often is GHDL and UVVM tested are there specific versions I should be using.

Thanks

Adam T

Hi Adam,

They should work together, and we do test that, - but there are occasionally some issues due to the development of both.  
I’ll check this out and we’ll come back to you soon.

Hi Adam,

I checked with Erick in the UVVM team, who gave the following info:  
**GHDL 5.0.0-dev (4.1.0.r298.ga3b41ea25) [Dunoon edition]**  
**Compiled with GNAT Version: 10.5.0**  
**static elaboration, mcode JIT code generator**

And this apparently works in general, but is seems there is a problem with the script for the UART example, with a couple of files missing. We will fix this ASAP.

A fix has been added now 🙂
