do the intel fpga need a global reset signal or not ? If needed, the reset signal should be input using special IO pin or not?

[zlan01]

can general IO pin be used to input the reset signal ?

Quartus will decide whether or not to promote the reset to use Global network based on several factors (i.e fanout). You can internally generate a reset source. If you decide to use an input pin, make sure to synchronize them to avoid metastability issue.
