Synthesis Example
Compile schematic below for any MAX 7000 device with MLS = OFF (standard synthesis)
- Compilation will fail (the design will not fit)
- All 37 input pins try to feed one macrocell
- In MAX 7000, there are only 36 signals from the PIA into each LAB
With MLS = ON, the design will compile using 2 macrocells
- Macrocell #1 will have fan-in = 36; macrocell #2 will have fan-in = 2
- MLS limits the fan-in to 36 (changeable) for every macrocell
