    The "mono-direction connection operator", aka the "coercion operator".

    For consumer :#= producer, all leaf members of consumer (regardless of relative flip) are driven by the corresponding leaf members of producer (regardless of relative flip)

    Identical to calling :<= and :>=, but swapping consumer/producer for :>= (order is irrelevant), e.g.: consumer :<= producer producer :>= consumer

    Symbol reference:

    • ':' is the consumer side
    • '=' is the producer side
    • '#' means to ignore flips, always drive from producer to consumer

    The following restrictions apply:

    • The Chisel type of consumer and producer must be the "same shape" recursively:
      • All ground types are the same (UInt and UInt are same, SInt and UInt are not), but widths can be different (implicit trunction/padding occurs)
      • All vector types are the same length
      • All bundle types have the same member names, but the flips of members can be different between producer and consumer
    • The leaf members that are ultimately assigned to, must be assignable. This means they cannot be module inputs or instance outputs.

    Additional notes: - Connecting two util.DecoupledIO's would connect bits, valid, AND ready from producer to consumer (despite ready being flipped) - Functionally equivalent to chisel3.:=, but different than Chisel.:=

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.
