Automatic Verification of Mixed-Level Logic Circuits
An approach is described to the specification and verification of digital systems implemented wholly or partly at the analog level of abstraction. The approach relies upon specifying the behaviours of analog components (such as transistors) by piecewise-linear predicates on voltages and currents. A decision procedure is described that can, for a wide class of specifications, automatically establish the correctness of an implementation.
