9 years ago --- Quote Start --- You're doing the right thing - dividing down the clock with a counter.If you want to instantiate a PLL I strongly recommend you use the MegaFunction/MegaCore Wizards. You can instantiate them in other ways. However, with little/no experience you should use the tools that are there to prevent you making mistakes. Note: in Cyclone V the lowest frequency you can generate from the PLL is 5MHz. So, to flash that LED - in a manner in which you can see it flashing - you will still need the counter. Cheers, Alex --- Quote End --- Dear Alex good evening, thank you so much for your reply on my posting. I am trying to get the hang of this thing! Of course there are like 1 billion more things for me to learn but i am really trying my best here! I will use the MegaFunctions provided by the Quartus software. I only hope that i can understand of the generated code for the PLL and not to fry my brain completely !!! :D But on a layman's language the autogenerated PLL from the MegaFunction is been created in Verilog or VHDL? Or some other "arcane" way? Is there any way to read the design created by the MegaFunction? Best regards and thank you so much, Panos.
