24 channel USB logic analyzer on FPGA

This is really interesting FPGA project because it has 24 logic input channels that is sampled at high rate while stream data is sent to PC via high speed USB 2.0 port – what means hundreds of megabytes.

Logic analyzer is built under Altera Cyclone II FPGA (EP2C5T144C7N) and a NET2272 USB controller from NetChip. Board is USB powered with necessary voltage converters on board.

The board has three connectors :

  • 10-pin connector for JTAG configuration of the FPGA. Its pinout is ready to be used with Altera Byteblaster cable.

  • 10-pin connector is for connecting a serial FPGA configuration device;

  • 26-pin connector is for connecting the probes.

Author provides full schematics of logic analyzer, source and a quickly written Linux driver to get board running.

  1. This is a great project. Woiuld it be possible to email me the schematics and driver to try it???

  2. i would love to build a logic analyzer on fpga. would u email me the schematic & the source? thank you very much.

  3. This looks really interesting would yo be able to email me the schematic and the source? thanks a lot

  4. Your FPGA logic analyzer is really an outcome to the problem I have. Would you email me the files and information I need to use this logic analyzer?
    Thank you very much.

  5. Hi

    This is what I am looking for … can you send me the schematic please.
    cheers
    simon

  6. Is it possible to send also me a documentations of project.

    Best Regards.

  7. Im interested in doing the FPGA logiz analyzer. Can u sent me the schematic and source? Thanks.

  8. real world uses windows…
