Boolean Expression Diagrams Revolutionize Chip Verification

Verifying complex computer chips used to be a nightmare until this specific data structure changed

the game. It’s called a Boolean Expression Diagram, or BED. For years,

engineers used Binary Decision Diagrams, but those would crash and run out of memory the second

you tried to verify something complex like a multiplication circuit. BEDs fixed this

by keeping the logic operators inside the graph itself. The researchers proved it by taking

two massive 16-bit multipliers that standard methods couldn't touch. With BEDs,

they verified the circuits were identical in less than a second. It basically turned an impossible exponential

problem into a linear solution.
