Hi @Matt Venn , @Tim Edwards @jeffdi and Everyone I am creating a board-level document for mpw-one since I just received chips. As per the below image I am not seeing VDDIO_PAD in sky130_ef_io.v Am I missing anything?

What do you have in
sky130_ef_io.v
? The VDDIO pads should be there.

the name is VDDIO and P_PAD, but there is no pin name with VDDIO_PAD - this is what we see i =n chip_io.v which is coming from caravel.v VDDIO_PAD is what I am not seeing. Not sure if i am missing something

First off, in the first screenshot you're pointing to the instance inside the cell, not the cell itself, which has the pin
VDDIO_PAD
. But otherwise, your PDK looks way out of date, because the entry should look like this:
Copy code
// sky130_ef_io__vddio_hvc_pad with HV clamp connections to VDDIO and VSSIO

module sky130_ef_io__vddio_hvc_clamped_pad (AMUXBUS_A, AMUXBUS_B,
        VSSA, VDDA, VSWITCH, VDDIO_Q, VCCHIB, VDDIO, VDDIO_PAD, VCCD,
        VSSIO, VSSD, VSSIO_Q
);

Ok Let me reinstall the latest PDKs and post findings
