Abstract
In one approach for improving timing in an electronic circuit design having a finite state machine (FSM), control bit logic is generated based on next state logic of the FSM that generates current state bits of the FSM. The control bit logic and a control state bit are added to operate in parallel with the next state logic and the current state bit registers, and the output signal from the control bit register replaces selected logic in logic downstream from the FSM and current state bit registers. If a worst case delay is improved with the design having the control bit logic and control state bit, the modified circuit design is saved for evaluating other possible timing improvements. Otherwise, the modification is discarded.
