1 Sequential Circuit Design 1.1 Background There is a game called Screwball. Every time a ball is put in play, either player 1 scores a point or player 2 scores a point. A winner is declared when one player is ahead by 2 points. Starting with a score of 0:0 for P vs. P2, a game might progress as follows: 0:0, 0: 1, 1:1, 1:2, 1: 3: P wins. 1.2 Problem Description Your task is to develop a synchronous sequential machine that uses information about which player scores a point at each game stage to indicate BOTH when a player wins and which player wins. Your design should include one reset input to initialize your WIN ANNOUNCER (this may be a synchronous or asynchronous input as you desire). The outputs from your design should indicate BOTH when a win has occurred and which player is the winner. You are required to follow the typical procedure for sequential circuit design. Implement the design on Logisim and verify its functionality. 1.3 Inputs The circuit is expected to receive two inputs. If the first input is zero, P wins this round, while one means that P2 wins the round. The second input is the reset; no reset is invoked if the reset is zero, while one refers to system reset. 1.4 Outputs The circuit is expected to generate two outputs; the first output declares a winner. The second output refers to the winning player; zero means that the first player is the winner, while one means that the second player is the winner. 1 Sequential Circuit Design 1.1 Background There is a game called Screwball.
