-==== 1. Download the Project ==== 
  
-Download the project zip file which can be found here: {{:basys3:abacus_demo.zip|}} \\ +===== Downloads =====
-Once you have downloaded the project, unzip it in the location of your choosing.+
  
 +Basys 3 Support Repository -- [[https://github.com/Digilent/Basys3/archive/master.zip|ZIP]] [[https://github.com/Digilent/Basys3|GIT Repo]]
  
-**Tcl Script Format**+------ 
 +===== How to...  =====
  
-The new project format is available for this demo and can be downloaded {{:tcl_basys3_abacus.zip|here}}. \\ 
-If you are unfamiliar with how to run projects in this new format, see the [[http://www.instructables.com/id/How-to-run-Digilent-Tcl-format-projects/|guide]]  on the usage of the new project format. Please read the short document included within the project folder. 
  
-==== 2. Load the Vivado Project ==== 
  
-In your now unzipped project, open the file abacus_demo.xpr. This should open your project in Vivado.  
  
-*The screenshots below are from another project but should look relatively the same and will work for our purposes.+==== 1. Generate the Project ====
  
-{{:basys3:gpio_load.png?600|}}+>1.1) Download the repository linked in the download section and place it in the location of your choosing. 
  
-==== 3. Synthesize, Implement and Generate Bitstream ====+>1.2) Generate the **Abacus** project in the Projects folder by following this guide before continuing: [[vivado:github|How to Generate a Project from Digilent's Github]]
  
-To complete this step all that you need to do is click **Generate Bitstream** on the left hand menu towards the bottom. Vivado will run through both Run Synthesis and Run Implementation before it generates the bitstream automatically. If you want, you can click each step by itself in the order of **Run Synthesis**, **Run Implementation** and then **Generate Bitstream**.+==== 2. Build the Project ====
  
-{{:basys3:buildflow.png?600|}}+>2.1) Click **Generate Bitstream** on the left hand menu towards the bottom. Vivado will run through both Run Synthesis and Run Implementation before it generates the bitstream automatically.

-===== Running the Basys3 Abacus Demo =====+
  
 To run all the features of this demo, all you will need is your programmed Basys3. The abacus can preform 4 arithmatic functions on two 8-bit numbers. Switches 15-8 represent input A. Switches 7-0 represent input B. The abacus works by setting the slide switches to your desired operands and then selecting an operation with the buttons. The result will be displayed on the 7 segment display. On startup, the display will read 0. To run all the features of this demo, all you will need is your programmed Basys3.
