QII to QIISP2 Migration, Warning: Entity "xxx" contains only dangling pins

Due to some issues during compilation, where the compiler declared that I could not connect an incoming clock signal to a logic device input, I decided to move to the Quartus II Version 9.0 Service Pack 2 Web Edition.

It is in general no good design practice to use external clock signals for other applications than clocking registers and flip-flops (or as inputs to PLLs).

So the compiler is hinting you not to do this. Switching to other versions of the software is not a solution to the basic problem.

Hope this helps...
