@User: Make sure you have the most recent magic techfile from open_pdks. To see what the issue is, there are several things to do: (1) Use "feedback find" to move to some of the errors; use "feedback why" to confirm that this is an issue raised with the PPLUS layer. Then increase the area of the box around the area and type "cif see PPLUS" to see what the PPLUS GDS layers looks like. If there are not clear width or spacing errors in the layer, then it is probably okay. (2) Use klayout, or use magic with the "sky130A-GDS.tech" technology file, to read back the GDS file and look at the PPLUS layer (which SkyWater calls PSDM, which is what it is called in the klayout layers), which should confirm whether or not the layer has a problem. "Parent and child disagree on CIF" errors are not necessarily a problem, but they can be.
