An invalid attribute 'related_ground_pin' is found #391

Expected Behavior

I want to convert .lib file to .db file for DC by Synopsys Library Complier.

Actual Behavior

However，when Library Complier reads sky130_fd_sc_hd__ff_100C_1v65.lib, it reports multiple errors similar to the one below.

Error: Line 57389, Cell 'sky130_fd_sc_hd__dlclkp_1', pin 'M0', An invalid attribute 'related_ground_pin' is found. (LBDB-27)

In line 57389:

57386 pin ("M0") { 57387 direction : "internal"; 57388 internal_node : "M0"; 57389 related_ground_pin : "VNB"; 57390 related_power_pin : "VPWR"; 57391 } 57392 statetable ("CLK GATE","M0") { 57393 table : "L L : - : L,L H : - : H,H - : - : N"; 57394 }

How do I fix this type of error?

Looks similar to what was discussed in #183, can you post a comment there instead?
