SPI clock input and output pins on Intel FPGAs

Are there any special instructions that one must or should follow in pinout when there are SPI input and output clocks in the design? i.e are there specific pins that must be used for SPI SCLK input ...

Hi

If you would like to use the clock in clock network, then you shall use clock pins.

Thanks.

What problems should one expect if the clock pin is not used? Are those problems surmountable?

    Hi

    If there is no timing issue, that should be fine. And only if the clock signal is not going to be ref clk for PLL usage.

    Thanks.
