Hello, I use a custom PDK over OpenROAD. On the Yosys side, it replaces all the cells with those defined in the Liberty file. Although

LOGIC0

and

LOGIC1

are defined in the Liberty file, the don't_use variable is true for both of them, so Yosys doesn't utilize them. However,

LOGIC0

appears as one of the cells in the final GDS file generated by OpenROAD. How can I prevent OpenROAD from using

LOGIC

cells and force it to use the cells synthesized by Yosys?

You have probably tried this but you can comment out the tie cells in the platform config file. you can also try commenting out those cells in the pdk files.
