AIM:
To write a VHDL program for 4-Bit Comparator and simulate it by using XILINX8.2i Software.
SOFTWARE:
1.XILINX 8.2i
2.ISE Simulator
PROCEDURE:
1.Start the Xilinx ISE software by Double clicking on the Icon or
Start → All Programs → Xilinx ISE 8.2i → Project Navigator
2.Create a new project by Selecting File > New Project...
3. Create a VHDL source file, then, continue either to the “Creating a VHDL Source” section below.
4. The next step in creating the new source is to add the behavioral description for the program.
5.Place the cursor just below the begin statement within the program architecture.
6. Save the file by selecting File → Save.
7.When the source files are complete, check the syntax of the design to find errors and types.
8.Verify the Functionality using Behavioral Simulation.
9.Create a test bench waveform containing input stimulus you can use to verify the functionality of the program module.
10. Save the waveform.
RESULT:
The VHDL program for 4-Bit comparator is written and simulated by using XLINX8.2i version and the Output is verified.
