Package structure
The chisel3 package presents the public API of Chisel. It contains the concrete core types
UInt,SInt,Bool,FixedPoint,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.
