Hi,

it is a board with an cyclone III EP3C40. My input frequency is 50 MHz.

there is no error in compilation report.all things is fine.

Only when i send my configuration data to pll(over pio) it does not output a frequency.

I will try to compile the PLL with 40 MHz and see if it stay stable.

Thanks
