These two simulation files needed?

[srvedulageth]

Hi,
set fileset_sim [list ./../../neorv32/sim/neorv32_tb.vhd ./../../neorv32/sim/sim_uart_rx.vhd]

When we test this on board, xc7a100tcsg324-1
Do these two files needed?

My understanding is ROM is pre-loaded and uart terminals of Neorv32 are connected to UART(via USB2UART bridge).

I just synthesized and programmed the board without these files and it still worked.
I was able to load blink led application code too.
I think they are not really needed.

This is correct for an actual (physical) implementation.

Do these two files needed?

All the sources in sim are only required for simulation and are (in most cases) not synthesizable anyway.

However, for Vivado it does not hurt if they are added to the fileset_sim file set, as these files are only used for simulation and not for the actual implementation.

Thank you.
