object Log2
Returns the base-2 integer logarithm of an UInt.
- Source
- CircuitMath.scala
Log2(8.U) // evaluates to 3.U Log2(13.U) // evaluates to 3.U (truncation) Log2(myUIntWire)
- Note
The result is truncated, so e.g. Log2(13.U) === 3.U

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.
