Honored ContributorMAX 10: a clock for SPI
Is using an external clock without a clock buffer causing any problem? I'm implementing SPI slave. An external SPI clock is directly from a pin(not a clock pin, but just an IOpin) of the FPGA...

Honored ContributorWhat speed are you trying to run your SPI at? An ordinary I/O pin should quite happily be able to operate as a clock for a small amount of logic.
Have you posted all the code driven by sclk? How have you constrained your design? If so then I suspect your constraints are not quite right. Add them to the post. Cheers, Alex
