Hello @User @User @User, I was checking the magic log files for the

spm

design and

myowndesign

and in the magic.drc.log , I found out that it was not drc clean. The list of errors it has are as follows:

Cell sky130_fd_sc_hd__o22a_4 couldn't be read
DEF read, Line 159 (Error): Cell sky130_fd_sc_hd__o22a_4 is not defined.  Maybe you have not read the corresponding LEF file?

DEF read, Line 170 (Error): Cell sky130_fd_sc_hd__inv_8 is not defined.  Maybe you have not read the corresponding LEF file?

and the list continues... What do these errors represent? The fact that they are even present in

spm design

doesn't make sense. The magic.log file however has no drc errors and when I open

spm.mag

layout on magic it is drc clean. the errors only appear in

spm.drc.mag

layout. Why is that so?
