5 years agoclkp and clkn inputs in Intel FPGAs
The clkp and clkn can be used to insert a differential clock signal into the FPGA. My question is, can we have 2 separate independent single ended clock signals being input into the FPGA on these two...

5 years agoHi,
Yes, it is possible to use both P and N pins as independent single-ended clock inputs, in MAX 10 and Cyclone 10 LP devices.

5 years agoThe different dedicated clock pins feed different GLCK networks. Is the fitter able to link different GCLK networks together so a single pin can feed the whole device? How does it achieve this?
Also, why does fitter allow user to use general purpose I/O pin to input a clock signal?
