 ====2. Creating Program File==== ====2. Creating Program File====
-For the four ways to program your Cmod A7 FPGA there are two file types available; .bit and .bin files. Using a .bit file we can use either the JTAG programming cable, or a standard USB storage device to load the bit file into the FPGA. Programming with a .bin file will use the QuadSPI to program the FPGA each time it is powered on. This means you will not have to reprogram it each time via a micro USB cable or by a thumb drive. The following steps bellow will get you all prepared to program your Cmod A7.+For the two ways to program your Cmod A7 FPGA there are two associated file types available; .bit and .bin files.

->2.1) In order to program the FPGA on startup we have to specify that we want to generate a .bin file. This can be done by clicking Tools> Project Settings> Bitstream. In this window we will check the box next to .bin_file. Now Vivado will create both a .bit, and .bin file when we generate a Bitstream.+>2.1) In order to program the FPGA on startup we have to specify that we want to generate a .bin file.

Vivado will notify you that since you have changed some things after synthesizing your design, your synthesis may become "out of date" with respect to your current project; go ahead and click Ok anyway. Vivado will then ask where you want to write unsaved constraints (even though we did not change any constaints); go ahead an choose the existing file that was used with this project and click Ok. Then click "Generate Bitstream" in the Flow Navigator on the left side.

 This will program your Cmod A7 through the JTAG connector. Once the programming window is closed go ahead and test out your board. Each slide switch at the bottom of your board should now toggle its respective LED on and off. This will program your Cmod A7 through the JTAG connector.

 Quad SPI Flash is a non-volatile memory that the Cmod A7's FPGA chip looks at on every startup. If Quad SPI is flashed then the FPGA will program itself with the contents found in Quad SPI's flash memory. This method of programming your board is great when you have a final project that you would like to demo or display that doesn't need to be edited and therefore reprogrammed. Quad SPI Flash is a non-volatile memory that the Cmod A7's FPGA chip looks at on every startup.
