it is simply an increased noise level in the measured values, related to the amount of irregular activity in the nios during measurement. just little, but intolerable. --- Quote End ---
Ah okay, so your next easy fix would be stalling NIOS with the waitrequest trick as Kero suggested. But that will bring back your missed interrupts, even though it's anytime more elegant than gating the CPU clock. But then, does not have the same effect, some flops might still be toggling.
What you didn't mention is where NIOS is getting its code and data from, external memory?
Looks to me that you should consider a respin of your board.
