Simple Tip to Save you Some Priceless Time !
In order to reduce compilation time use the rapid recompile option:
On Quartus settings dialog box (Assignments menu -> Settings) under Compilation Process Settings -> Incremental Compilation, turn the Rapid Recompile option ON.
With this option ON, the compiler reuse compilation results to update design for small changes.
Another option to reduce compilation time is to configure Quartus to use all the processors available in the PC running Quartus.
Compilation Process Settings -> Parallel Compilation -> Use All Available Processors
One last option is to use the Smart Compilation option. Smart compilation can reduce compilation time by skipping compiler stages that are not required to recompile the design. Smart compilation skips entire compiler stages (such as Analysis and Synthesis) when they are not required. This feature is different from incremental compilation, which you can use to compile parts of your design while preserving results for unchanged parts.
Compilation Process Settings -> Smart Compilation, turn the Smart Compilation option ON.
Note: these are simple solutions to simple designs. For complex designs there are other options that will be detailed in other blog.
