.pof file generates "top level design entity" undefined error - .pof file generates "top level design entity" undefined error .pof file generates 12007 "top level design entity" "undefined" error, in a MAX 10 design which self-identifies as 10M08SAU169 , under Quartus Prime Version 20.1.1 Build 720 Windows 7 64 . Under Quartus II, where are the 2 items which are being compared and are mismatched ? Replies: Re: .pof file generates "top level design entity" undefined error Agree with @sstrell Replies: Re: .pof file generates "top level design entity" undefined error Because a .pof is not a design file so it can't have a top-level entity. Like I said, you need a design file (.v, .vhd, .bdf, .qsys, etc.). Replies: Re: .pof file generates "top level design entity" undefined error So it sounds like it is an error for Quartus to allow a compilation project to be based on a .pof ? Why would this result in a top-level-design-entity undefined error. Replies: Re: .pof file generates "top level design entity" undefined error A .pof is a binary programming file. You can't open it. It's an output of the Assembler, part of the compilation process. You need the original HDL (.v or .vhd) or schematic design files (.bdf) to open and look at the design. You can't do anything with a .pof other than program a device or flash with it.

What type of files are input to the Quartus project? The error message that you had mentioned is encountered when conditions mentioned in the following help link occur: https://www.intel.com/content/www/us/en/programmable/quartushelp/13.0/mergedProjects/msgs/msgs/esgn_top_entity_is_missing.htm Regards Replies: Re: .pof file generates "top level design entity" undefined error Wherever I have seen that question, I have told it to set it to the Top Level Design Entity. Is there a simple way to dump out the exact contents of the .pof file? Is there any way to Edit the .pof file ? I did not create it and am not sure what is in it, but the project name selected "must exactly match the entity name in the design file" . Replies: Re: .pof file generates "top level design entity" undefined error Did you set the top-level entity/module before starting the compilation?

When you program the device flash? Does your project compile successfully?
