HELLO; I use Quartus II web version 12.0 sp2 web edition to encode small program the order of TPs. when I compile the file itself with "Analyze Current File", everything goes well without error. But when I compile the whole project, I get this error: error (12007) top-level design entity "project" is undefined Thank you for helping me to solve this problem.

Hello, "Error: Top-level design entity "*NAME*" is undefined" This is what I did to correct. 1) check paths for spaces, none allowed. 2) check entity name can not start with number. 3) Assignment - Settings - General - Top-Level Entity - "..." 4) From bottom up. select next entity up. Apply - OK. 5) Processing - "Start Compilation" 6) When complete. Tools - "Netlist Viewers" - "RTL Viewer" Don't know if this step is necessary. It's what I did. 7) Repeat from step 3) moving up for each entity in list. 8) when finished, one last time with first (bottom/original) "Entity Name" 9) Done This created what was missing that was needed. I worked for me hope it works for you.
