A config example file for axi_intercon_gen.py

[tunghoang290780]

Hello,

@accuminium

Is there any config example file used as the input of axi_intercon_gen.py script? I try axi.core but it seems not working

Thanks!

Hi @tunghoang290780,

Thanks for your question.

axi.core contains an example configuration for axi_intercon_gen. Have you tried that? If yes and it does not work, what errors do you get?

Hi @accuminium

I hope my running command is correct ./scripts/axi_intercon_gen.py axi.core I got errors as below (I am using python-3.6.9 and Ubuntu 18.04)

axi.core is the Manifest file for FuseSoC, and it is not intended to be an input file to scripts/axi_intercon_gen.py.

Instead, you need to write a separate file that describes how your interconnect instance should be configured. axi.core contains an example configuration. Based on that example, you could write the following my_xbar.yml file:

vlnv: pulp-platform.org:axi:xbar:0.27.1
parameters:
  masters:
    dma:
      id_width : 1
    ibus:
      id_width : 2
  slaves:
    ram:
      offset : 0
      size: 0x10000000
    gpio:
      offset: 0x91000000
      size: 0x1000
    rom:
      offset : 0xffff0000
      size : 32768

Invoking python3 scripts/axi_intercon_gen.py my_xbar.yml will then create an axi_intercon.v in the current directory, which instantiates axi_xbar as you defined in my_xbar.yml.
