I need to create clock definition on combo logic output. What is the way to do clock definition?
I tried to add LCELL on the combo gate output and tried creating clock on LCELL.out pin. However, this did not work.
Can you please help with some way to define clock on combo logic output?
Thanks for your help!!
although it's generally bad design practice and typically causes problems in timing closure, it's basically possible to feed a register clock port from a LCELL output. It's however not possible to feed e.g. a PLL input. What are you exactly trying to achieve?
Have you check on the documentation regarding the clocking mode in Arria 10? You can refer link below:
