Expand description
Standard parasitics exchange format (SPEF) parser.
§How to use
See SPEF::parse_str.
We also support transforming a SPEF object to a SPEF source
code, by using std::fmt::Display.
§Misc
This parser obeys the IEEE 1481-1998 standard, with some notable exceptions (to be addressed in future work):
- prefix bus delimiter
:,.unsupported (because they interfere with hchar.), and empty suffix bus delimiter is unsupported yet. - sensitivity is unsupported in cap and res defs. and slew threshold is unsupported in conn attr.
- Pi model is unsupported.
