SIMULATION AND IMPLEMENTATION OF MULTIPLIER **AIM: ** To simulate and synthesis multiplier using Xilinx ISE.

APPARATUS REQUIRED: Xilinx 14.7 Spartan6 FPGA

PROCEDURE: STEP:1 Start the Xilinx navigator, Select and Name the New project. STEP:2 Select the device family, device, package and speed.
STEP:3 Select new source in the New Project and select Verilog Module as the Source type.
STEP:4 Type the File Name and Click Next and then finish button. Type the code and save it. STEP:5 Select the Behavioral Simulation in the Source Window and click the check syntax.
STEP:6 Click the simulation to simulate the program and give the inputs and verify the outputs as per the truth table.
STEP:7 Select the Implementation in the Sources Window and select the required file in the Processes Window. STEP:8 Select Check Syntax from the Synthesize XST Process. Double Click in the FloorplanArea/IO/Logic-Post Synthesis process in the User Constraints process group. UCF(User constraint File) is obtained. STEP:9 In the Design Object List Window, enter the pin location for each pin in the Loc column Select save from the File menu. STEP:10 Double click on the Implement Design and double click on the Generate Programming File to create a bitstream of the design.(.v) file is converted into .bit file here. STEP:11 On the board, by giving required input, the LEDs starts to glow light, indicating the output.
