Five-Variable K-Map: Cross-Fold Adjacency

MediumLogic CircuitAnalyze

Hardware synthesizers map complex logic functions into multi-dimensional boolean spaces to identify optimal transistor sharing. A five-variable Karnaugh map visualizes a 32-cell space by stacking two 16-cell maps representing A=0 and A=1.

The variables B, C, D, and E define the axes for both sub-maps. The Boolean function F has logic 1s at minterms m(0, 2, 8, 10) in the A=0 map and m(16, 18, 24, 26) in the A=1 map.

Evaluate the spatial relationships between the two sub-maps. Determine the prime implicants of F and identify the optimized Boolean expression.

Constraints

  • Minterm notation uses m(val) where the concatenated bits ABCDE form the binary index.
  • The maps use standard Gray code ordering for the BC and DE axes.
