Details

Type pdaExpression

Define an expression.

Expression need to be commonly evaluated by many software, so having a restricted set of math / types and so on is key. In PDAFlow lib2/expr there is a yacc/lex parser available with some unit support as well as double / complex expressions. An alternative is tinyexpr, but this is more restrictive, so may be very unhandy for things like waveguide model expressions.

doc

Type pdaDocumentation documentation: Document anything relevant for the topic you want to define.

This field allows some (short, few lines) documentation to be written. It can be a long string, but the idea is not to replace a design manual.
This fields is like tex which allows documentation in LaTex format; doc is restricted to plain text.

max

Optional maximum value which can be used for design rule checking or user interface aspects. Type pdaExpression documentation: Define an expression.
