Abstract

A finite-state machine has combinatorial logic connected to a status memory which receives future state signals from the finite-state machine and sends current state signals to the finite-state machine. The combinatorial logic also receives and generates input and output signals which are external to the finite-state machine. The finite-state machine compares the future state signals to at least one reference level to set an error message to reset the finite-state machine for reliable computing and adjustment.
