While the VCD format separates the timescale and the timestep (likely to allow representing the timestep with a small integer type), time in CXXRTL is represented using a uniform 96-bit number, which allows for a ±100 year range at femtosecond resolution. The implementation uses `value<96>`, which provides fast arithmetic and comparison operations, as well as conversion to/from a more common representation of integer seconds plus femtoseconds. |
