See AN351 https://www.altera.com/support/support-resources/design-examples/intellectual-property/embedded/nios-ii/exm-simulating-niosii.html 

 

Use a JTAG UART with a BSP configured to use that UART as STDOUT, and then just use printf() from your application software. 

The JTAG UART will use $write() to output your characters.
