Hello, does anyone know what's the reason for encountering this error when I perform the precheck for the GFMPW-1?

@Uriel Jaramillo Sorry, I missed your message. Is this still a problem or was it resolved with the new tag?

I just ran it now after making some modifications, and it still shows the same errors

@Uriel Jaramillo I sorted by gpio number and got this

Looks like you have not connected

io_oeb

for each gpio pad. The simplest solution is to connect each

io_oeb

to low for output and high for everything else.

Where should I make that configuration?

verilog/rtl/user_proj_example.v

.

assign io_oeb[11:0] = {12{1'b1}};
assign io_oeb[37:12] = {26{1'b0}};

assign io_out[11:0] = {12{1'b0}};

Thank you very much. The OEB passed, but I still have some LVS errors that I can't resolve. Here is the LVS_check.log

@Uriel Jaramillo the LVS is “passing” but the results are incomplete. Can you add the netlists for the cells in

precheck_results/11_NOV_2023___14_17_05/outputs/reports/lvs.unflattened

to your

lvs/user_project_wrapper/lvs_config.json

file? Also can you share the

lvs.unflattened

file here?

Thank you very much, all the checks passed
