Assignment 3 and 4 is accidentally merged in ass-3. Sorry for the inconvenience.

1. Download the assignments - git clone https://github.com/SayantanRC/xilinx_assignments.git or Click on the green download button and extract it.
2. Download Xilinx 14.7 ISE from https://www.xilinx.com/support/download/index.html/content/xilinx/en/downloadNav/design-tools.html
3. Install it. For Linux users, the following script maybe useful:

#!/bin/bash
#<xilinx_installation_dir> is usually /opt/Xilinx
#if you are installing somewhere else, make a symlink:
#sudo mkdir -p /opt/Xilinx && sudo ln -s <xilinx_installation_dir>/14.7 /opt/Xilinx
source <xilinx_installation_dir>/14.7/ISE_DS/settings32.sh
cd <xilinx_installation_dir>/14.7/ISE_DS/ISE/bin/lin64
./ise

4. Open the assignments by File->Open Project option.
5. In the Open project window, navigate to the assignment folder and open the assignment_name.xise file.

1. In the left Design column, click on the Implementation radio button.
2. Click on a testbench file (ending with tb in the name)
