/// \brief Verilator: Include to allow symbol inspection
///
///     This file is for inclusion by files that need to inspect the symbol
///     table.  It is not included in verilated.h (instead see
///     verilated_sym_props.h) as it requires some heavyweight C++ classes.
///
///     These classes are thread safe and read only. It is constructed only
///     when a model is built (from the main thread).
///
/// Code available from: https://verilator.org
