Hi, I want to use basic PDK Sky130 cells for part of my design. I manage to make it work with RTL simulations. But when I try to use the same code to be process by openlane I get and error in that part because it does not recognize the cells. How I need to configure openlane to allow to use basic cells ? thanks

You need to set specific configuration in config.tcl. See openlane's documentation

Add set ::env(SYNTH_READ_BLACKBOX_LIB) 1, if you have std cells hard coded in your RTL.

perfect thanks
