I generated an uart core from qsys and made a simulation with modelsim.I instantiated two uart (one as transmitter and one as receiver); I connected the "uart_0_external_connection_txd" pin of the transmitter to the "uart_0_external_connection_rxd" pin of the receiver. The uart transmitter seems work properly but I can't get the signal "uart_0_s1_dataavailable=1" from the receiver uart and the rxdata register is always 0. Do you have any suggestion? Thank for your help
Hi Galfonz,thank you for your reply. I'm using the uart core for simulation purpose in modelsim. I don't think I can put a pull up resistor for simulation. How can I do that?
