ResetType

final class ResetType extends Element with Reset

"Abstract" Reset Type inferred in FIRRTL to either AsyncReset or Bool

Source
Bits.scala
Note

This shares a common interface with AsyncReset and Bool but is not their actual super type due to Bool inheriting from abstract class UInt

    Does a reinterpret cast of the bits in this node into the format that provides. Returns a new Wire of that type. Does not modify existing nodes.

    x.asTypeOf(that) performs the inverse operation of x := that.toBits.

  11. def autoSeed(name: String): ResetType.this.type

    Takes the last seed suggested.

    Takes the last seed suggested. Multiple calls to this function will take the last given seed, unless this HasId is a module port (see overridden method in Data.scala).

    If the final computed name conflicts with the final name of another signal, the final name may get uniquified by appending a digit at the end of the name.

    Is a lower priority than suggestName, in that regardless of whether autoSeed was called, suggestName will always take precedence if it was called.

    returns

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 and chisel3.CompileOptions 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.
