Hi,I am trying to design a carrier board for a Cyclone 5 part, but am a little confused on how to design the power rails. On page 7 and 8 of https://www.altera.com/content/dam/altera-www/global/en_us/pdfs/literature/an/an734.pdf it says to "provide separate power sources for all rails that can be shared between the HPSand FPGA circuitry", but does this mean each HPS/FPGA part on page 8 needs to have its own regulator? Or is it possible that regulators can be shared? Thank you!
Hi,--- Quote Start --- but does this mean each HPS/FPGA part on page 8 needs to have its own regulator? Or is it possible that regulators can be shared? --- Quote End --- Meaning, Use separate regulators and its outputs can be shared between FPGA & HPS. Separate regulator without sharing.
Ok, so you mean this is fine then -https://www.alteraforum.com/forum/attachment.php?attachmentid=15757 Basically there will only be one regulator for the 1.1V, but separate lines branching from it to FPGA and HPS. Is this okay? Sorry for the messy diagram
