# read all the library cells used during synthesis

read_alf /apps/cadence//jointfilesconvert/375363/bg40/lib/lca500k.alf

# transform lca500kv to a name called "target_techology" for future use

set_global target_technology lca500kv

# include wireload models into library elements

read_library_update /apps/cadence//jointfilesconvert/375363/bg40/lib/lca500k.wireload3

}
