# Test SPEF reader with different name mapping styles and corner handling
# Targets: SpefReader.cc uncovered functions:
#   findPinRelative (line 176, hit=0)
#   findPortPinRelative (line 182, hit=0)
#   findInstanceRelative (line 159, hit=0)
#   setDesignFlow (line 300)
#   setDivider, setDelimiter, setBusBrackets
#   setCapScale, setResScale, setTimeScale, setInductScale
# Also targets: SpefParse.yy (more parser paths)
#   SpefLex.ll (more lexer paths)
#   ConcreteParasitics.cc (parasitic network creation/query paths)
#   Parasitics.cc (findParasiticNetwork, makeParasiticNetwork)
