ContributorHow to constraint min delay between LCELLs?
Hi,
Right so I don't think this constraint works on LCELLS alone. Because you would need a setup/hold relationship in the first place.
Which brings us back to using set_data_delay, which definitely should work on LCELL alone.
Since it isn't supported on Quartus II 13.1, I suggest you migrate to Quartus Standard 21.1 as this would have the set_data_delay.
On the other hand, you are using LCELL to generate a pulse to wake up the clocks right? Maybe you could consider using clock control IP: https://www.intel.com/content/dam/support/jp/ja/programmable/support-resources/bulk-container/pdfs/literature/ug/ug-altclkctrl.pdf
