Four-Variable K-Map: Basic Grouping with a Group of 8
Logic synthesis tools rely on Boolean minimization to reduce transistor counts and optimize propagation delay. The Karnaugh map below represents a four-variable Boolean function F(A, B, C, D).
| AB \ CD | 00 | 01 | 11 | 10 | |---|---|---|---|---| | 00 | 1 | 1 | 1 | 1 | | 01 | 1 | 1 | 1 | 1 | | 11 | 0 | 0 | 0 | 0 | | 10 | 1 | 1 | 0 | 0 |
The top two rows correspond to A = 0 and are completely filled with 1s. The bottom row contains two additional 1s in the first two columns.
Determine the optimal groupings to produce the minimal sum-of-products expression for F.
Constraints
- Groupings must follow standard Karnaugh map rules for adjacency and power-of-two sizing.
- The final expression must be in minimal sum-of-products (SOP) form.
- Literals should be written in alphabetical order.
