UART DPI error in Vivado Version 2022.2 #320

I get the following error when I run 'make all-vivado' command in Vivado version 2022.2 without any changes made.

Time resolution is 1 ps
run -all

What is the Vivado version that was originally tested on?

Hi @mertkorkut, thanks for your interest in the CORE-V-MCU. Unfortunately, the Vivado simulator does not support all the code constructs in the MCU's RTL. I keep hoping one day it will. In the meantime, I will push in an update to the vivado targets to make this obvious to users.

For RTL simulation I suggest you try Verilator, v5.008 or newer.
