The same program compiled 20 minutes or so, sometimes, and sometimes to compile an hour, what reason is this?

CodePudding user response:

Timing constraints unchanged is the PC itself,

CodePudding user response:

Is there any solution

CodePudding user response:

Will sometimes use is incremental compilation, and sometimes didn't open this

CodePudding user response:

I never use incremental compilation, should not be this reason
