Simulating Jtag-Uart as an input

[Altera_Forum]

Hello, 

 I'm simulating an SOPC design that includes a NIOSII and a Jtag-Uart with Modelsim. My problem is that I can use the Jtag-Uart as a program output, but not as an input.  To go into details, SOPC Builder automatically creates: - jtag_uart_output_stream.dat (empty output stream) - jtag_uart_input_stream.dat (example input stream) - jtag_uart_log.bat (example script that seems to redirect the Jtag-Uart ouput to the file jtag_uart_output_stream.dat)  When using the example script during simulation, a console appears, and I can see the characters sent by the NIOS program being displayed.  Now I don't know what to change in the example script to allow the console (or the file jtag_uart_input_stream.dat) to be used as an input to the program.  Has any of you done that before?  Thanks in advance!  Jean-Christophe

I also cannot get JTAG UART input to work in ModelSim. Altera does not seem to provide usable information on that subject.  

 Have you made any progress yet?

--- Quote Start ---  Altera does not seem to provide usable information on that subject.  --- Quote End ---   I'm under the impression, that they clearly declared all virtual JTAG functionality as unsupported in simulation. I think, the only solution is to write a special component replacing the JTAG UART for simulation purposes.
