Objectives: To learn and practice schematic entry and simulation. Problem: Implement an ALU (Arithmetic Logic Unit) satisfying the following functional requirements. You should complete schematic capture tutorial, before you start on this lab. Select (S) A. Function SI SO 4 Invert ALU Add Subtract Double A + B A - B 1 1 2*A Figure 1: ALU Port Interface and Function Table 1. (10 pts) Design and create a schematic of the ALU using ISE Schematic Entry tool. 2. (10 pts) Create a test bench and use it to test the ALU functionality. Include at least two test vectors per function. Objectives: To learn and practice schematic entry and simulation.
