Fitter Settings Dialog Box
Expanders per Logic Cell (0% to 1000%): - MAX 7000 default (100%): 1:1 - (MLS or Standard Synthesis)
- MAX 9000 default (100%) : 0.5:1
This option allows the user to control the ratio of shareable expanders to macrocells for the design.
For example, if a design requires 100 macrocells in a MAX 7000 device, the maximum number of shared expanders used will be 100. If the percentage is decreased to 50%, then 50 expanders may be used for a 100 macrocell design.
For MAX 9000 devices, 50 and 25 expanders each may be used.
Fan-In per Logic Cell (10% to 200%): - MAX 7000 default (100%): 36
- MAX 9000 default (100%): 33
- Only available with MLS selected
This option allows the user to control what the maximum fan-in is for each macrocell. For example, if a MAX 7000 design is compiled with this option set to 50%, then the maximum fan-in to each macrocell will be 18.
Logic Cells per Row: - MAX 9000 default (100%): 80 - (MLS or Standard Synthesis) This option allows the user to control how many logic cells are placed on each Row. This option may be useful for designs with high pin and low macrocell count.
