VHDL coding in Xilinx

  1. 1. Following are the steps for writing and simulating VHDL code in Xilinx ISE environment. 1) Create New project from File Menu. Compiled By: Naveen Kumar Email: chd.naveen@gmail.com Info-techgeek.blogspot.in
  2. 2. 2) Give the file name Compiled By: Naveen Kumar Email: chd.naveen@gmail.com Info-techgeek.blogspot.in
  3. 3. 3) Select options as shown below: Compiled By: Naveen Kumar Email: chd.naveen@gmail.com Info-techgeek.blogspot.in
  4. 4. 4) Press ‘Next’ two times in the follow-up windows and then ‘Finish’ at last. 5) Select New Source by clicking on project in sources window as shown below: Compiled By: Naveen Kumar Email: chd.naveen@gmail.com Info-techgeek.blogspot.in
  5. 5. 6) Select VHDL Module and name the file. Then click Next Compiled By: Naveen Kumar Email: chd.naveen@gmail.com Info-techgeek.blogspot.in
  6. 6. 7) Give port declarations as we do in entity. Then click Next. And then Finish. Compiled By: Naveen Kumar Email: chd.naveen@gmail.com Info-techgeek.blogspot.in
  7. 7. 8) VHDL Code is presented on the screen. Now we just have to write the code in architecture. Compiled By: Naveen Kumar Email: chd.naveen@gmail.com Info-techgeek.blogspot.in

  9. 9. 9) Select New Source by clicking on project in sources and then select Test Bench Waveform and name the file. Then Click Next two times and then Finish. Compiled By: Naveen Kumar Email: chd.naveen@gmail.com Info-techgeek.blogspot.in
  10. 10. 10) A new window appears as shown below. For combinational circuits select combinatorial clock. Compiled By: Naveen Kumar Email: chd.naveen@gmail.com Info-techgeek.blogspot.in
  11. 11. 11) Set the input waveforms by clicking on the waveform at different time intervals. Compiled By: Naveen Kumar Email: chd.naveen@gmail.com Info-techgeek.blogspot.in
  12. 12. 12) Select Behavioural Simulation from sources window. Compiled By: Naveen Kumar Email: chd.naveen@gmail.com Info-techgeek.blogspot.in
  13. 13. 13) Under Processes window simulate the file. 14) The output simulations is observed at last. Compiled By: Naveen Kumar Email: chd.naveen@gmail.com Info-techgeek.blogspot.in
