2.9.4.1. FSM Explorer in Synplify Pro and Premier

The Synplify Pro and Premier software use the FSM Explorer to explore different encoding styles for a state machine automatically, and then implement the best encoding based on the overall design constraints. The FSM Explorer uses the FSM Compiler to identify and extract state machines from a design. However, unlike the FSM Compiler, which chooses the encoding style based on the number of states, the FSM Explorer attempts several different encoding styles before choosing a specific one. The trade-off is that the compilation requires more time to analyze the state machine, but finds an optimal encoding scheme for the state machine.
