    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.:=

    (Since version 2.12.16) Use formatString.format(value) instead of value.formatted(formatString), or use the f"" string interpolator. In Java 15 and later, formatted resolves to the new method in String which has reversed parameters.

  2. def →[B](y: B): (Bits, B)

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.
