Simulating JTAG to Avalon

Hi,

You'll need to use BFM simulation. This tutorial document link https://forums.parallax.com/discussion/download/110606/altera_jtag_to_avalon_mm_tutorial.pdf under section 3.5.3 JTAG-to-Avalon-MM Master probably can clear your doubt.

Attached the tutorial design file jtag_to_avalon_mm.zip below for your reference. May refer to the example testbench sopc_system_jtag_master_tb.sv and execute the run_simulation.tcl with simulator.

Simulation result as below screenshot:

If you encounter compilation error in simulator, remember to temporarily comment out some lines (if else statements) in ../sopc_system/simulation/submodules/altera_avalon_st_jtag_interface.v like below screenshot in order for altera_jtag_sld_node (node) to link with sopc_system_jtag_master_tb.sv:

Thanks,

Best Regards,

Sheng
