# read_spef -name <spef> only parks the parasitics under <spef> in the
# parasitics_name_map_; it does NOT bind them to any Scene (this is the
# deferred-binding flow for MCMM -- see examples/mcmm3.tcl and Sta::readSpef
# in search/Sta.cc). Without an explicit Scene binding, report_dcalc /
# report_checks would see only pin capacitance (~0.57 fF here) and produce
# incorrect table lookups, instead of the wire-cap-annotated ~13.97 fF we
# expect for this design. define_scene with -spef spef creates a Scene
# bound to the -name'd Parasitics via Scene::setParasitics and makes it the
# current Scene, so Prima receives the full RC network.
