Design steps When we design a sequential circuit, we will start from a description or a specification of the task that we want the circuit to perform then follow these steps to realize the circuit. - Design starts from a specification and results in a logic diagram or a list of Boolean functions - The steps are : - Derive a state diagram - Assign binary values to the states - Choose the type of flip flop to use - Obtain the state table - Utilizing the characteristic tables of the flip-flop - Get the simplified input equations and output equations - Draw the logic diagram Circuit design specification Design a counter circuit that count forward and backword based on the input X. If the input is 0 it should count forward 0,1,2,3,4,5,6,7,0,1,2,. If the input is 1 it should count backward 7,6,5,4,3,2,1,0,7,6,5
