# Test SDF advanced features: timing checks, write options, multiple reads,
# gzip write, divider options.
# Targets uncovered SdfReader.cc paths (timing checks, interconnect, cond_use),
# SdfWriter.cc paths (gzip, divider, digits, no_timestamp, no_version,
# include_typ), and SdfParse.yy grammar paths.
