XOR Functionality
Product-Term Select Matrix
With XOR Synthesis logic option NOT selected
- The XOR gate can be used for inversion or for XOR functions already specified in the design (existing XOR gates)
- MAX+plus II will not create new XOR gates
- Glitches are less likely to occur, but more resources will be needed
With XOR Synthesis logic option SELECTED
- MAX+plus II can minimize a design by creating new XOR gates that feed combinatorial (non-registered) logic cells
- This may save resources (logic cells and product terms)
- This may introduce glitches to some designs
