New ContributorUse case of SLD hub controller
I want to use SLD hub in MAX-V FPGA.
The sink of SLD hub would be SLD node in the FPGA fabric.
How about the source of SLD hub ? , what is it's input ? (channel and protocol).

Hi,
sld_hub_controller is used as lower level interface in sld_hub_controller_system and jtag-over-protocol IP, which are the hardware interfaces of documented remote debug solutions, see AN693 and AN971. The interfaces and protocols are not documented as such.
altera_streaming_sld_hub_controller_core.sv source has however meaningful comments, variable and state names, it's not too difficult to understand the intended usage. A testbench can help to figure out control timing.
MAX V has limited debugging capabilities due to low LE count, which debugging functions are you looking for?

Hi Farabi,
I have look the diagram.
Its from AN 693: Remote Hardware Debugging over TCP/IP for Altera SoC.
How the SoC can be replaced with the FPGA to debug over TCP/IP.
I want to debug the MAX-V FPGA.
thank you.
- FvMDon't understand why you rely on using MAX V for the project. It has no on-chip RAM and can't implement Signaltap.
There's a principle option to implement hardware TCP/IP stack in FPGA (probably needing more logic cells than provided by MAX V), but it's not supported by any Intel IP.
A processor-less remote debug interface can be easier implemented through other fast serial links.- Peter01
Hi Frank,
I can replace MAX V with MAX10.

I have planned this initially but dropped due to complexity.

A processor-less remote debug interface can be easier implemented through other fast serial links.This exactly suits my application . Could you provide suggestion to remote debug (signaltap) .I am aware of using JTAGD (Linux JTAG server) on x86 platform and using USB blaster. But this doesn't fit in my requirement.A hint on use of SLD hub controller for remote debug would be appreciated.Thank you.

Hello,
I am sorry for late reply. You may want to explore remote debugging setup from this link : https://www.intel.com/content/www/us/en/support/programmable/articles/000078790.html
By enabling JTAG over network, you can use all the Quartus features including signaltap from remote.
