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 typesBundle
andVec
.The Chisel package is a compatibility layer that attempts to provide chisel2 compatibility in chisel3.
Utility objects and methods are found in the
util
package.The
testers
package defines the basic interface for chisel testers.
