Spam-1 is a breadboard build btw and I have no experience of fpga.
I use verilog as it allowed me to simulate all the 7400 components during the build.
The uart model I wrote for the ftdi device was useful for my Sims as I can interact with it over a file.
I don't know how useful it would be for your use case. I don't consider baud rates when thinking about this stuff because like I say the "terminal" in my case are files not a serial cable.
Perhaps some more info.

Perhaps you have some code to show and discuss?

Also since I use Icarus verilog and not verilator there will be mods needed.
It would be good if these could be added to my model using #defines rather than creating an disconnected model if possible.
I can't exactly recall why I don't use verilator - I'm sure there was a reason. Icarus verilog isn't super fast tho it does allow me to run with realistic propagation delays which has helped spot errors.

What do you mean by not considering baud rate? Are you using an automated
port of some sort that takes care of the baud rate itself?
All I need is also some sort of a terminal.
I'm currently researching things and I'm having trouble understanding how
one can simulate UART in cpp.
btw thank you for your fast response.
Maybe I can get back to you with some code to discuss later. I really
appreciate your will to share your knowledge with me.
I was using icarus at first too but had trouble with giving it user input
(dynamically setting some wires to have specific values or something like
that). Any resources in that area would be appreciated.

Icarus can take input from the console if you want to interact with the
simulation.
Baud has nothing to do with my uart model. It's just a model of a uart that
behaves like a um245r to the rest of the verilog SIM and connects to file
io on the local filesystem for external interactive things. There is no
terminal and no serial line so no baud.
