ILA and Vivado via Petalinux

I'd like to use the Vivado Integrated Logic Analyzer (ILA) and connect to it over the network. Additionally, I'd like this connection to be made via the PS on the same Zynq chip as the PL being monitored.

It looks like Vivado can be pointed at a network device for the connection. See http://www.xilinx.com/support/documentation/application_notes/xapp1251-xvc-zynq-petalinux.pdf. However, that app note requires a second board and looks to me like just a way of building a network dongle instead of using the USB dongle sold by Xilinx. I'd like a solution that doesn't require managing an additional board/piece of hardware.

I've found a related (though possibly more general) question at https://forums.xilinx.com/t5/7-Series-FPGAs/Is-it-possible-to-control-PL-JTAG-from-PS-in-the-same-Zynq-FPGA/td-p/672775, which suggests that it's not possible to do what I'm after given that the ILA is controlled via JTAG.

Is there another variant of the ILA (or configuration option) so that the ILA can be accessed over the AXI bus instead of over the JTAG? Is there another tool that I haven't found yet that does what I'm looking for?

Thanks,

Tom

Hello Tom,

Your second link is broken but I was able to find the post with a search.

This is a good question. I don't know the answer for sure, but it post implies that you might be able to do this with an external connection from the AXI-JTAG signals back to the Zynq JTAG inputs. Probably a better question to follow up with on the Xilinx forums. Let us know if you do find out more on this method.

The only other related post I could fine is this one: http://zedboard.org/content/jtag-axi-and-ila-issues

If any of our other forum users have done something like this please let us know how it worked.
