Hi dmitryl,

As far as I know you can use any pin as global, local, regional or peripheral clock when you use Altera's ATLCLKCTRL IP block. The IP block allows you to "promote" a certain signal to travel over dedicated spines, e.g. the global spine which covers the entire FPGA, or a local clock spine, which covers only certain area of the FGPA etc.
