Compile Without Assignments Initially
Compile the project with default settings and without any assignments (pin, logic option, synthesis style, etc¡¦) initially
Arbitrarily or globally selected assignments can prevent the design from fitting in the device (compilation may fail)
Evaluate the results: resources (logic cell usage), performance, pin placement
- If these results are sufficient, no further work is necessary
- If optimization is required, see Resolving Fitting and Performance Issues Sections
