We present a succinct formulation of the timing constraints for latch-controlled synchronous digital circuits. We show that the constraints are mildly nonlinear, and prove the equivalence of the nonlinear optimal cycle time calculation problem to an associated and simpler linear programming (LP) problem. We present an LP-based algorithm which is guaranteed to obtain the optimal cycle time for arbitrary circuits controlled by a general class of multi-phase overlapped clocks. We illustrate the… CONTINUE READING
