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.
This is the documentation for Chisel.
Package structure
The chisel3 package presents the public API of Chisel. It contains the concrete core types
UInt,SInt,Bool,Clock, andReg, the abstract typesBits,Aggregate, andData, and the aggregate typesBundleandVec.The Chisel package is a compatibility layer that attempts to provide chisel2 compatibility in chisel3.
Utility objects and methods are found in the
utilpackage.The
testerspackage defines the basic interface for chisel testers.
