Intellectual Property (IP) Cores
In this lecture I will explain what an IP core is and how they are used when developing hardware.
In this lecture I will give a quick demonstration of why one would want to use IP cores over traditional Hardware Descriptive Language (HDL) programming.
This lecture shows step by step how to take hardware design files inside your Vivado project and turn them into IP cores. These IP cores can be placed in a block design inside Vivado.
This lecture explains how to create a custom IP core from a block design inside your Vivado project. This IP core can be saved into your custom IP core repository to be used again and again.
This lecture introduces the AXI interface and how it is used. We will use the AXI interface so that our IP cores can be controlled by the Micro Blaze softcore processor. We will actually use AXI IP cores in the “Working with Softcore Processor” section.
This lecture explains how to create an AXI IP core so that you can interface your IP core with a Micro Blaze soft core processor. The AXI IP cores can also be interfaced with the hard ARM cores located on Xillinx’s System on Chip (SoC) such as the Zynq.
This lectures walks through the steps of interfacing your HDL design with the AXI IP core generated HDL files.
This lecture walks through the steps of locating and placing your custom IP core with an AXI interface.
This lectures shows students how they can customize their IP cores. This lecture also shows how to attach a PDF document to their IP Core.
In this lecture I will walk through the steps required to create your own IP core repository. These custom IP Core repositories are nice because you can then reuse your designs from various projects.
This lecture suggests different ways you can structure your IP core repository so that as you add more and more IP cores you can still stay organized.
At this point you know how to create your own IP cores from a block design, a specific directory, as well as creating IP cores with an AXI interface. In this lecture I am going to show you how to add IP cores to a specific repository.
This lecture walks through the steps in how to add a IP core to your custom directory.
This lecture talks about the types of maintenance that is required for an IP repository.
IP Core Design Examples
This lecture shows step-by-step how to customize and initialize the FPGA’s internal block RAM using IP cores available through Vivado.
This lecture walks through the steps required to generate an external memory interface for your design. This is very useful when you plan on implementing a softcore processor or other memory heavy design.
When working with large designs and integrating soft/hard core processors, multiple AXI IP cores will likely be used. This lecture shows how to connect multiple of these IP cores to a single AXI master, which is usually a processor.
Vivado has a neat tool that is useful for increasing productivity as well as keeping your block designs clean. In this lecture you will be shown how to utilize Vivado’s auto-router and regenerate your block designs.
Working with Design Constraints
This is an introduction to design constraints, it explains what they are, were and how they are used. This lecture also explains what will be covered in this section.
This lecture shows how to add I/O constraints to your design. I/O constraints include the logic level, physical pin location, as well as the type of signal implemented on the specified pin.
Complex designs typically require multiple clocks running at different frequencies. This lecture shows how to add new clocks to your design at various frequencies.
Automating Vivado
This lecture walks through and introduces as well as explains what a TCL script is and does. This is a powerful skillset to have as many other engineering tools use TCL scripts.
There are several ways to create a project in Vivado, the most straightforward being to use the new project wizard. However, if you are creating a lot of projects and they all are using the same parts / settings then creating a custom TCL will save a lot of time. In this lecture you will be shown step-by-step how to use TCL scripts to create a Vivado Project.
This lecture shows how to create a block design, add IP cores to the newly created block design, and connect the IP cores all from a TCL script. These TCL scripts can be used again and again throughout different projects.
This lecture will show how to add custom TCL scripts to your IP core. These TCL scripts can then be used to add further customization to your IP cores.
When working with revision control software its ideal to have the smallest file sizes possible. Instead of checking in entire projects and generated files, it’s possible to only check in TCL scripts and source files. This lecture will show you how to generate a TCL script that will re-generate your project and block design.
Hardware Design Debugging and Verification
This lecture discusses the required format of a test bench file for use in the Vivado Tool Suite. There are several example test benches included as well.
In this lecture a step-by-step example is shown on how to simulate your design using Vivado’s internal simulation tool. This is a very powerful tool that can be used when trying to debug and verify your design prior to the actual implementation.
This lectures shows ways to manipulate the simulated waveform for analysis. There are step-by-steps showing how to do the following:
- Zooming in/out or to a specific region
- Measuring time between signal edges
- Adding waves to the window
- Saving a waveform configuration file
- Change the format of a signal (radix)
While your troubleshooting / simulating your design using Vivado’s simulator you may need to generate inputs without having to modify the test bench. This lecture shows how to force an input or internal signal to a specified value to help aid in the debugging process.
This lecture explains the different tools provided in the Vivado Tool Suite that are available to help you debug and verify that your design is working properly. Debugging hardware design is extremely challenging, but Vivado has some very powerful tools available to help you test and verify your design.
The Integrated Logic Analyzer Core is a logic analyzer that resides in your FPGA design while running. This core has many capabilities that an external logic analyzer would contain as well. In this lecture I am going to show you how to use the ILA debugging core.
The virtual I/O core is very useful for debugging designs; it can be used to see what is happening while your design is running. This is very useful because there are occasions when your simulation works but your design does not. In this lecture I am going to show you how to use the VIO debugging core.
Working with Soft Core Processors
In this lecture we walk through the steps of creating a softcore processor project in Vivado. We will be using the MicroBlaze softcore processor.

This lecture lists out the project requirements to successfully complete this project.
This lecture discusses the process of selecting an FPGA based on a set of requirements.
Once the device has been selected a project must be created. This steps walks through the process of creating a project based on the device selected.
In this step we will be adding the IP cores we are using to implement our final project. This can be as simple as making sure your custom IP repository contains the desired IP cores.
In this step we will be creating / editing the constraints file we need for our final project.
A very important step in the design process is to simulate your design. In this step we will be simulating our final project design.
Once we are confident our design is working correctly we need to generate the FPGA configuration file. This lecture will show how to generate the configuration file.
The final step to complete our design is that we want to program our board and verify that the design is working as we expect. In this lecture we will walk through the steps to program your FPGA using Vivado’s Hardware Manager.
