The Qsys pictures below better describes the problem. If I attach the system clock pin to N14 I must add a second altpll (altpll_1) or the compiler will fail in fitter. If I attach the system clock pin to N9 then I can use a single altpll (altpll_0) and compile without errors.

I am wondering why fitter cannot connect to N14 with a single altpll.
