Fitter Settings
Normal Fitting: This is the default option. MAX+plus II may insert LCELLs after I/O pins with assignments if necessary to route the design. If LCELL insertion is not desired, select Custom Fitting and then toggle the Auto LCELL Insertion Options.
Advanced Try Harder/Longer Compilation Fitting: Recommendation: this option should only be used as a last resort to achieve a successful compilation. This option directs MAX+plus II to cycle through a predefined suite of different Fitter settings to attempt to find a fit. This option will cause the Compiler to run for a longer period of time (e.g., overnight) while attempting a fit. If you select this option and fitting is successful, you can manually specify the successful settings (listed in the report file) for Custom Fitting to accelerate future recompilations.
