axi_address_resolver relies on non-existing module

[bchetwynd]

The axi_address_resolver component relies on the find_first_one component, which is not part of the repository. The axi_address_resolver component is used in axi_lite_xbar.sv.

Thus, when attempting to simulate using compile_vsim.sh / run_vsim.sh scripts, the simulation fails due to undefined module.

I'm not entirely sure what the local testbench does, however you can find all the IP dependencies in the Bender.yml file. In this case, what you need is http://github.com/pulp-platform/common_cells .

I think the IP owners (@fabianschuiki @zarubaf ?) should explicitly call bender to fetch these in their script.

[bchetwynd]

Clarification much appreciated.

[zarubaf]

Yes, @FrancescoConti is completely right. Currently we do not provide our bender flow as open-source. If you want to use the testbench you are welcome to do so but you need to resolve your dependencies manually. The find first zero can be found in the common cells repository as Francesco mentioned.

Thank you. For what it is worth, the find_first_one module is contained in a deprecated directory. However, including that file as suggested addresses the issue in the axi_lite_xbar.sv module.

@bchetwynd is that by any chance Brendon from WPI end of 90s?

[bchetwynd]

Yes, indeed :) Hello, Frank!

You can theoretically already use Bender, but you would have to compile it from source yourself (https://github.com/fabianschuiki/bender). We're still ironing out the flow of that tool and will provide precompiled binaries once things become more stable. But just in case you're feeling lucky 😉 .
