trait IsLookupable extends AnyRef
A User-extendable trait to mark metadata-containers, e.g. parameter case classes, as valid to return unchanged from an instance.
This should only be true of the metadata returned is identical for ALL instances!
- Source
- IsLookupable.scala
For instances of the same proto, metadata or other construction parameters may be useful to access outside of the instance construction. For parameters that are the same for all instances, we should mark it as IsLookupable
case class Params(debugMessage: String) extends IsLookupable class MyModule(p: Params) extends MultiIOModule { printf(p.debugMessage) } val myParams = Params("Hello World") val definition = Definition(new MyModule(myParams)) val i0 = Instance(definition) val i1 = Instance(definition) require(i0.p == i1.p) // p is only accessable because it extends IsLookupable

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.
