object ListLookup
For each element in a list, muxes (looks up) between cases (one per list element) based on a common address.
- Source
- Lookup.scala
ListLookup(2.U, // address for comparison List(10.U, 11.U, 12.U), // default "row" if none of the following cases match Array(BitPat(2.U) -> List(20.U, 21.U, 22.U), // this "row" hardware-selected based off address 2.U BitPat(3.U) -> List(30.U, 31.U, 32.U)) ) // hardware-evaluates to List(20.U, 21.U, 22.U) // Note: if given address 0.U, the above would hardware evaluate to List(10.U, 11.U, 12.U)
- Note
This appears to be an odd, specialized operator that we haven't seen used much, and seems to be a holdover from chisel2. This may be deprecated and removed, usage is not recommended.

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.
