In my experience it is difficult to make the NIOS CPU run over 100MHz without a pipeline bridge before the JTAG debug module.

Hmmmmm... This is interesting to me. I have been having trouble getting text to display correctly on the Nios II Console using prntf() statements. A little text like "Hello World" display fine, but add more text and it stutters terribly. I've been thinking that it is probably due to JTAG UART timing somehow, but other features like SignalTap that us JTAG seem to work fine.
Could you describe how to insert a pipeline bridge in the JTAG Debug module interface? Maybe this would solve my problem.
Thanks in advance, I've learned a lot from your posts.
