This repository contains VHDL files of different Digital Designs.

VHDL-Programs

Why I made this repository?

VHDL is not a very popular language with a huge user base, hence there is very little to no content regarding this language.

I struggled to get familiar to this language due to lack of proper content online, so feel free to use this repository to learn how to code different circuits/designs in VHDL.

How to run these files/projects?

• You firstly need to have Xillinx ISE Design Suit installled on your system.
• After opening the software click on File -> New Project
• Enter name of project and then select the configuration as
  • Device Family: Spartan3
  • Device: xc3s50
  • Package: pq208
  • Speed: -4
  • Top-Level Source Type: HDL
  • Synthesis Tool: XST (VHDL/Verilog)
  • Simulator: ISim (VHDL/Verilog)
  • Preferred Language: VHDL
  • Property Specification in Project File: Store all values
  • Manual Compile Order: false
  • VHDL Source Analysis Standard: VHDL-93
• Now click on Add Source and select the downloaded files.
• Import these Files
• Click on Simulation Radio Button
• Left click on the testbench file and click on the Simulate behavioral model under the ISim Simulation drop down.
• You have your required waveform output.
• In order to see the circuit diagram click on Implementation radio button and click on RTL Schematic Option and double click on the entity diagram shown.
