Tutorial: Using the USB-Blaster as an SOPC/Qsys Avalon-MM master

Hi Tim,

--- Quote Start ---

I use Quartus 15.0.1 and Modelsim 10.3d. I tried to redefine VTAP as dut.jtag_master.jtag_phy_embedded_in_jtag_master.node but still failed to load the design qsy_system_jtag_master_tb.sv. Does anybody know to fix this problem?

I suspect Altera has changed the internal implementation of their components (yet again), so the path to the JTAG tasks has changed. To determine the correct path, you could look at the code, but that is tedious ... the quick solution is to use vim to load just the Qsys system (rather than the testbench), and then use the Modelsim GUI to navigate down the component hierarchy. Once you find where it no longer matches the testbench, you can fix the path in the testbench code.

If you cannot figure it out, let me know, and I'll take a look.

Cheers,

Dave
