ChipScope is a set of tools made by Xilinx chipsvope allows you to easily probe the internal signals of your design inside an FPGA, much as you would do with a logic analyzer. Afterwards, you chipsccope these cores in your Verilog code, and you connect those modules to the signals you want to monitor.

Make sure Virtex II is selected as the device family. This chispcope where you will connect the signals you wish to analyze. The trig0 port on the ILA should be connected to the signals that you wish to probe with the ChipScope analyzer.

This site ika cookies More info No problem. Now, let’s change the trigger setup to trigger when the lower eight bits of the count bus are all zero.

Click on the chupscope Generally, ChipScope sampling rate will be the same as the design’s clock frequency. Indeed, I am working on one such project at the time of this writing. During the “Translate” portion of the design compilation process, the. This means that you may have to keep on rebuilding your design to access the signals of interest and route them out to the test header.

Under Trig0, choose a trigger width of The complete design is then recompiled. To group analyzer channels into a bus, expand the “Data Port” item in the window pane labeled “Signals: Select core type to generate: Click “OK” to dismiss the “Configur We might also specify certain chipscops conditions upon which we desired the tool to commence storing data for subsequent ipa and analysis. 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.

Make sure the top-level module labkit is selected in the source tree, and double-click on “Generate Programming File in the processes window, to compile the design. In your project directory, you should now have a number of new files icon. Name the new bus count. As with the ICON core, the output netlist should be generated in your project directory, and the device family should be set to Virtex II.

Instead of loading the resulting.

Leave the remaining three checkboxes unchecked and click “Next”. At the end of the labkit. Set the output netlist field so that the ICON core is generated in the counter project directory, Make sure the output netlist name ends with. As with their physical counterparts, these virtual logic analyzers — like ChipScope from Xilinx, Identify RTL Debugger from Synopsys, Reveal from Lattice Semiconductor, and SignalTap from Altera — can be set up so that they will only start collecting data after certain trigger conditions have been met.

Watch the progress indicator in the lower-right corner of the ChipScope window. When the download completes, the LEDs on the chipcsope should start counting. The black-box definitions will look like this module icon control0 ; output [ This tutorial builds on the simple counter project, described in the Getting Started tutorial.

An ILA is a logic analyzer block which can trigger on internal signals and capture them inside a memory so that they can be viewed through the analyzer GUI. It ipa therefore not possible to detect glitches with ChipScope. This allows ilq to have different groups to choose from when you do your triggering at run-time. Select the “Data same as Trigger” box, which allows chipscoppe to view all the signals of interest, as well as to potentially trigger on all of them.

You only need one ICON in your design. If your design had multiple up to 15 ILA modules, each would be connected to a different control port on the ICON, using a unique bit control bus.

For example, while your design is running on the FPGA, you can trigger when certain events take place and view any of your design’s internal signals.

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.

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. One of the tools we would have employed would be a logic analyzer.

See Xilinx Answer Recordwhich recommends the following workarounds: Click “Select New File” in the dialog that appears, and then select the labkit. In some cases, the physical construction of the unit in question means that test headers are of use only at the board level and not during system integration.

One big advantage of these in-chip logic analyzers is that they offer the ability to capture the values on wide internal busses and store these values in internal RAM. Chipscole waveform window will display the captured waveforms.

Setting up the Ika Design This tutorial builds on the simple counter project, described in the Getting Started tutorial.

For Number of trigger ports, choose 1 for now, although for your design chiipscope are free to use up to This file also provides a dummy “black-box” definition of the core. The waveform window should now only contain the bit bus count. If you no longer have that project setup, create a new project in Project Navigator, and add the following files.

Start Project Navigator, and open the counter project.

When the waveform window updates, note that the eight LSBs of the value of the count bus at sample zero are zero. ChipScope Analyzer also provides the interface for setting the trigger criteria for the ChipScope cores, and for displaying the waveforms recorded by those cores.

This is a known bug in ChipScope 6.
