In src/axi_to_obi.sv, this PR removes the .testmode_i connection from the obi_mux instance i_mux_banks.

But obi_mux still has a testmode_i input:

• in obi 0.1.7, which this PR uses (see Bender.yml);
• on obi main.

So this input is now unconnected in every axi_to_obi. QuestaSim warns [TFMPC] Missing connection for port 'testmode_i'. Verilator warns PINMISSING.

obi PR #36 removes the input from obi_mux. Until axi_obi uses an obi version with that change, I suggest tying the input to 1'b0:

  ) i_mux_banks (
    .clk_i,
    .rst_ni,
    .testmode_i     ( 1'b0      ),
    .sbr_ports_req_i( obi_reqs  ),

This is safe: obi_mux only passes testmode_i to its internal fifo_v3.

I have used this change since October, with QuestaSim 2026.1 and Verilator 5.050. The warnings are gone, and my tests pass. If it helps, I can open a pull request against this branch.
