With the Quartus Prime tool, there is an option setting of "safe state machine". What disadvantages are there if this function is turned off?
I think that it is safe to organize it with a synchronous circuit, but is it still better to keep this setting effective?
A safe state machine in Quartus is a state machine that if it reaches an illegal state (for any exceptional reason, such as glitch, metastability, etc.), it will reach the reset state after one clock cycle.
