    A wrapper method for Module instantiation based on option choices.

    A wrapper method for Module instantiation based on option choices. (necessary to help Chisel track internal state).

    default

    the Module to instantiate if no module is specified

    choices

    the mapping from cases to module generators

    returns

    the input module m with Chisel metadata properly set

    Exceptions thrown

    java.lang.IllegalArgumentException if the cases do not belong to the same option.

    See also

    chisel3.choice.Group on how to declare the options for the alternatives. Example: val module = ModuleChoice(new DefaultModule)(Seq( Platform.FPGA -> new FPGATarget, Platform.ASIC -> new ASICTarget ))

SourceInfoTransformMacro

These internal methods are not part of the public-facing API!

The equivalent public-facing methods do not have the do_ prefix or have the same name. Use and look at the documentation for those. If you want left shift, use <<, not do_<<. If you want conversion to a Seq of Bools look at the asBools above, not the one below. Users can safely ignore every method in this group!

🐉🐉🐉 Here be dragons... 🐉🐉🐉

These do_X methods are used to enable both implicit passing of SourceInfo while also supporting chained apply methods. In effect all "normal" methods that you, as a user, will use in your designs, are converted to their "hidden", do_*, via macro transformations. Without using macros here, only one of the above wanted behaviors is allowed (implicit passing and chained applies)---the compiler interprets a chained apply as an explicit 'implicit' argument and will throw type errors.

The "normal", public-facing methods then take no SourceInfo. However, a macro transforms this public-facing method into a call to an internal, hidden do_* that takes an explicit SourceInfo by inserting an implicitly[SourceInfo] as the explicit argument.
