Why Arria10 doesn't support "incremental compiling" in Quartus Pro 19.2 - Why Arria10 doesn't support "incremental compiling" in Quartus Pro 19.2 Hello expert, I have a Arria10 Project, and it needs 2+ hours to compile it completely. The project debugging is very very slow , becasue we need to wait the project compiling completiob each time when we modify a bit code for further debugging. In Quartus Pro menu list, I found that "rapid compile" is grey, so I just wonder How can I enable "rapid compimling" to quicken the project compiling, to ease the debugging. Is there any method to enable "the incremental compiling" in my Arria10 Project ?

I will check internally. Can you upgrade to latest release 20.2? If no, you will have to use command line to run the rapid recompile. Put this to test.tcl and run it with quartus_sh -t test.tcl load_package design load_package flow project_open Test execute_flow -compile #execute_flow -recompile #execute_module -tool fit #execute_module -tool sta project_close Replies: Re: Why Arria10 doesn't support "incremental compiling" in Quartus Pro 19.2 I had "subscribe to board" in top-right down menu, but I didn't receive the reply in my registered email ? It's strange ~ Hi @KennyTan_Altera , I use "Quartus Prime Pro 18.1" .

I tested it in Q20.2pro edition and it is working. Also, you need to turn on enable intermediate fitter snapshots to use this feature.
