===== Tutorials =====

  * [[programmable-logic:guides:installing-vivado-and-vitis]]
    * Walks through installing Vivado and Vitis, the development environments used to create hardware and software applications targeting Digilent FPGA development boards.
  * [[programmable-logic:guides:getting-started-with-ipi]]
    * Walks through using Vivado and Vitis to create a design in hardware and software that uses a processor to control buttons and LEDs.
  * [[programmable-logic:guides:getting-started-with-vivado]]
    * Walks through using Vivado to create a simple design that blinks a single LED.
  * [[learn/programmable-logic/tutorials/pmod-ips/start]]
    * Digilent Pmod IPs can be used to control connected Pmods from baremetal software.
    * It should be noted that not all Pmods are supported and that Pmod IPs are only supported in versions of Vivado 2019.1 and older.
  * [[programmable-logic/guides/simulation]]
    * Learn how to use Vivado's built-in simulator for the first time

  * [[https://forum.digilent.com/topic/27389-arty-a7-microblaze-ddr3-tutorial/]]
    * The user Viktor Nikolov posted a tutorial on the Digilent Forum showing an alternate architecture for clocking the DDR interface for Digilent boards when using MicroBlaze. It works around several errors that may occur in other guides linked here.
