PDK file path not exist - sky130_ef_io__gpiov2_pad_wrapped.v moved part of sky130_ef_io.v

[vijayank88]

Description

In libs.tech/openlane/config.tcl following configuration should be updated.

set ::env(GPIO_PADS_VERILOG) "\
    $::env(PDK_ROOT)/$::env(PDK)/libs.ref/sky130_fd_io/verilog/sky130_ef_io.v\
    $::env(PDK_ROOT)/$::env(PDK)/libs.ref/sky130_fd_io/verilog/sky130_ef_io__gpiov2_pad_wrapped.v\
"

Because $::env(PDK_ROOT)/$::env(PDK)/libs.ref/sky130_fd_io/verilog/sky130_ef_io__gpiov2_pad_wrapped.v file path not exist and sky130_ef_io__gpiov2_pad_wrapped module as part of sky130_ef_io.v

Reproduction Material

Following MPW shuttle design will re-produce this error: https://github.com/shalan/Caravel_Chameleon_SoC/blob/master/openlane/chip_io/config.tcl

Quick check in PDK path:

$ gvim OpenLane/pdks/sky130A/libs.ref/sky130_fd_io/verilog/
sky130_ef_io.v      sky130_fd_io.v 

Expected behavior

Following configuration will resolve the issues of missing file path:

set ::env(GPIO_PADS_VERILOG) "\
    $::env(PDK_ROOT)/$::env(PDK)/libs.ref/sky130_fd_io/verilog/sky130_ef_io.v\
    "
