Boundary Scan Testing MAX II

I'm trying to perform Boundary Scan testing on my programmed MAX II, and I can't seem to sample pins that are configured as outputs, Anyone know why?

This is because, by default the input buffers are turned off for I/O pins that are configured as outputs in your design.

To regenerate your programming file to enable this, you need to set the 'Always Enable Input Buffers' option in Quartus and re-run Assembler.

This option is in the Assembler section under the Assignments/Settings menu.
