The "strong connect" operator.
The "strong connect" operator.
For chisel3._, this operator is mono-directioned; all sub-elements of
this
will be driven by sub-elements ofthat
.- Equivalent to
this :#= that
For Chisel._, this operator connections bi-directionally via emitting the FIRRTL.<=

The "bulk connect operator", assigning elements in this Vec from elements in a Vec.
The "bulk connect operator", assigning elements in this Vec from elements in a Vec.
For chisel3._, uses the BiConnect algorithm; sub-elements of
that
may end up driving sub-elements ofthis
- Complicated semantics, hard to write quickly, will likely be deprecated in the future
For Chisel._, emits the FIRRTL.<- operator

asTypeOf[T <: Data](that: T): T
Does a reinterpret cast of the bits in this node into the format that provides.
Does a reinterpret cast of the bits in this node into the format that provides. Returns a new Wire of that type. Does not modify existing nodes.
x.asTypeOf(that) performs the inverse operation of x := that.toBits.

Reinterpret cast to UInt.
Reinterpret cast to UInt.
- Definition Classes

- Note
value not guaranteed to be preserved: for example, a SInt of width 3 and value -1 (0b111) would become an UInt with value 7
,Aggregates are recursively packed with the first element appearing in the least-significant bits of the result.

def
autoSeed(name: String): Clock.this.type
Takes the last seed suggested.
Takes the last seed suggested. Multiple calls to this function will take the last given seed, unless this HasId is a module port (see overridden method in Data.scala).
If the final computed name conflicts with the final name of another signal, the final name may get uniquified by appending a digit at the end of the name.
Is a lower priority than suggestName, in that regardless of whether autoSeed was called, suggestName will always take precedence if it was called.

SourceInfoTransformMacro
These internal methods are not part of the public-facing API!
The equivalent public-facing methods do not have the do_
prefix or have the same name. Use and look at the
documentation for those. If you want left shift, use <<
, not do_<<
. If you want conversion to a
Seq of Bools look at the asBools
above, not the one below. Users can safely ignore
every method in this group!
🐉🐉🐉 Here be dragons... 🐉🐉🐉
These do_X
methods are used to enable both implicit passing of SourceInfo and chisel3.CompileOptions
while also supporting chained apply methods. In effect all "normal" methods that you, as a user, will use in your
designs, are converted to their "hidden", do_*
, via macro transformations. Without using macros here, only one
of the above wanted behaviors is allowed (implicit passing and chained applies)---the compiler interprets a
chained apply as an explicit 'implicit' argument and will throw type errors.
The "normal", public-facing methods then take no SourceInfo. However, a macro transforms this public-facing method
into a call to an internal, hidden do_*
that takes an explicit SourceInfo by inserting an
implicitly[SourceInfo]
as the explicit argument.
This is the documentation for Chisel.
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.
