Purpose The purpose of this homework is to better understand how real-world device delays effect the maximum speed of operation in sequential synchronous designs. Assignment A sequential network has been implemented using two D flip/flops, and discrete combinational logic as shown in the figure below. Assume that the inputs A and B always change at the same time as the falling edge of the 50% duty cycle clock. Also assume the following delay parameters for the combinational logic elements: The...
