Honored ContributorHi All,
How can I know what pins could be used as the Global, Local, Regional, and Peripheral clocks in the ArriaV device (as an example)? What difference between these clocks? Where to read about (manual/tutorial/userguide)? Thank you!
Honored ContributorHow can i know what pins in ArriaV might be used as Global or Regional clocks?
In the ArriaV Handbook, in the Table 4-1 (see attached below), there is only mention what the pins are CLK[0..11] and CLK[16..23] for ST devices, but where the pin numbers themselves? Where can I locate the pins (know their pin numbers)? https://www.alteraforum.com/forum/attachment.php?attachmentid=11551Honored ContributorLook at the appropriate Pin-out file for your device. See pin-out files for altera devices (https://www.altera.com/support/literature/lit-dp.html#arria-v).
Under the Optional Function(s) column, you're looking for the CLK[0..11] pins. Cheers, AlexHonored ContributorThanks! As for the CLK[0..11] pins, they are the Global clock pins, are not?
But what pins might be used as the Local, Regional, and Peripheral clock pins? Thank you againHonored ContributorYes, they're global. However, you can also access the other resources from them. Refer to table 4-1 in the device handbook (https://www.altera.com/en_us/pdfs/literature/hb/arria-v/av_5v2.pdf) for all the options available.
