using Xilinx design tools. Place and route the design with ILA cores. Download bit-stream on to FPGA and analyze the signals using chipscope. Xilinx ChipScope ICON/VIO/ILA Tutorial. The Xilinx ChipScope tools package has several modules that you can add to your Verilog design to. If you are new to FPGAs, one aspect of the development flow you may not have considered is how you will go about debugging your design.

For this tutorial, you only need 1 match unit. To group analyzer channels into a bus, expand the “Data Port” item in the window pane labeled “Signals: Match units allow you to create different trigger vectors so that you can trigger on a sequence of different vectors: We might also specify certain trigger conditions upon which we desired the tool to commence storing data for subsequent display and analysis.

In some cases, the physical construction chjpscope the unit in question means that test headers are of use only at the board level and not during system integration.

ChipScope Analyzer also provides the interface for setting the trigger criteria for the ChipScope cores, and for displaying the waveforms recorded by those cores.

Debugging with ChipScope ( labkit)

Connect the programming cable to the JTAG port on the labkit, and power on the labkit. For example if your Trigger Width is 20, change it to It is therefore not possible to detect glitches with ChipScope.


Choose for data depth.

You have now generated all the necessary ChipScope hardware blocks, and are ready to include them in the existing counter design. If you are new to FPGAs, one aspect of the development flow you may not have considered is how you will go about debugging your design once it has been loaded into the FPGA.

Click “OK” to dismiss the “Configur Make sure Virtex II is selected as the device family. Using virtual logic analyzers may remove the need for test headers. One solution to this problem — a solution that has seen great advances over the last few years — has been the development of in-chip logic analyzers for use with FPGAs.

Generally, ChipScope sampling rate will be the same as the design’s clock frequency. Type eight zeros, and then return.

Sadly, however, in many cases they do not remove the need to rebuild the code.

The big downside with this approach comes in designs that are already utilizing most of the devices programmable resources, because chipscop will limit any logic analyzer implementations. At the end of the labkit. Click on the “T! This tutorial builds on the simple counter project, described in the Getting Started tutorial. Under clock settings, choose to sample on the rising edge of the clock.

Debugging with ChipScope

The sample memory chipscop the analyzer is limited by the memory resources of the FPGA. Leave the remaining three checkboxes unchecked and click “Next”.


This file also provides a dummy “black-box” definition of the core. This means that you may have to keep on rebuilding your design to access the signals kla interest chipscoope route them out to the test header.

Having configured the target device, you can then connect to the target over JTAG using the ChipScope Analyzer tool and trigger on the waveform of interest as illustrated in the screenshot below.

Logic analyzers are, of course, chipscoope employed today. This site uses cookies More info No problem. Start Project Navigator, and open the counter project. Example Verilog code showing how to instantiate the ILA core, and a dummy “black-box” definition of the core. ChipScope will begin downloading the. You only need one ICON in your design. For Number of trigger ports, choose 1 for now, although for your design you are free to use up to Also, ChipScope cannot sample as quickly chipscops an external logic analyzer.

Name the new bus count. Select the “Data same as Trigger” box, which allows you to view all the signals of interest, as well as to potentially trigger on all of them. Click “Select New File” in the dialog that appears, and then select the labkit. Watch the progress chipsfope in the lower-right corner of the ChipScope window. In your project directory, you should now have a number of new files icon.
