internal osc & global clk

is there way to get the internal osc on cyclone 3 or 4 use the global clk network? if so whats the .qsf command for that? i think the 80mhz internal osc is not using the global clk network.

Hi Wen,


May I know if the KDB given able to assign the internal oscillator to GCLK? Alternatively, in assignment editor, you can select global signal and assign global clock to the osc and you can reflect in your qsf.
