Flat LVS OK and deep failing

[FatsieFS]

Need some help to change a LVS deck to be compatible with hierarchical LVS checking. In testcase_deep.zip you can find the testcase I made for this case. When I run lvs_Sky130 in the directory I get the following:

~/eda/Chips4Makers/test/testcase_deep$ ./lvs_Sky130 
Running flat LVS
Flat LVS OK
Running deep LVS
Deep LVS Failed!

I zipped the directory with the output files of the runs included. This is a LVS deck automatically generated. Similar LVS decks are generated for all PDKs I support in project Arrakeen (see FSiC2024) and thus complementary to the upstream PDK ones.
