Slot-011 of mpw4 has a missing connection from

user_project_wrapper

to a child circuit.

wbs_stb_i

is not connected to

both

. From the top rtl, you can see that it is missing.

input wbs_stb_i,
...
both both(
`ifdef USE_POWER_PINS
        .vccd1(vccd1),  // User area 1 1.8V power
        .vssd1(vssd1),  // User area 1 digital ground
`endif

    .wb_clk_i(wb_clk_i),
    .wb_rst_i(wb_rst_i),
          .wbs_cyc_i(wbs_cyc_i),
          .wbs_we_i(wbs_we_i),
          .wbs_sel_i(wbs_sel_i),
          .wbs_dat_i(wbs_dat_i),
          .wbs_adr_i(wbs_adr_i),
          .wbs_ack_o(wbs_ack_o),
          .wbs_dat_o(wbs_dat_o),
          .la1_data_in(la_data_in),
          .la1_data_out(la_data_out),
          .la1_oenb(la_oenb),
          .io_in(io_in),
          .io_out(io_out),
//        .io_oeb(io_oeb),
//        .user_irq(user_irq),
          .active(active),
          );

but then in

gl/both.lvs.powered.v

there's

input wbs_stb_i;
...
 sky130_fd_sc_hd__buf_2 input55 (.A(wbs_stb_i),
