Hello,
I'm simulating the design using Modelsim Actel 6.6d, but I'm having an undefined value for the SOUT signal.
However, when I verified the internal signal iSOUT, it seems to be correctly. I also verified the signal imcr_loop and it seems to be ok.
Even at the begin of the simulation, when the reset is asserted, the value of iSOUT is undefined.
I think there is a problem with the process UART_OUTREGS in the uart_16750.vhd file.
Thank you,
Regards,
