ContributorWhy do the A/D's on MAX10 need blank pins around them? Unable to use.
I have a 10M08SA design that is about 80% full. Board level power supplies are being measured by the FPGA's ADC's. However, when I compile the design, synthesis fails and the indication is that almos...

ContributorYou might get round this by using the 'I/O Maximum Toggle Rate' attribute in the Assignment editor. Add this attribute to each signal in question and set its value to 0. This may tell (fool) Quartus into believing this signal will not cause any interference on the analogue signal.
Note: this will risk additional noise on the analogue signal if these digital signals are not (relatively) static.
Tip: add this parameter for one signal. Then edit the project's .qsf file adding a similar entry for each signal in question.
Cheers,
