 Solution

A fully synchronous sequential circuit has all its state stored in edge-triggered elements driven by a common clock signal, with combinational logic computing the next state from the current state and inputs. State updates occur together at the designated clock edges, rather than letting one register output serve as another register's ripple clock. Its ideal equations areFor a Moore machine the output function depends only on the state, $z_k=G(s_k)$. Physical design must leave enough time for register-to-register combinational paths and satisfy setup time and hold time at every receiving storage element.
