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.
that should have known widths
,bit widths are NOT checked, may pad or drop bits from input
Reinterpret cast to UInt.
Reinterpret cast to UInt.
Aggregates are recursively packed with the first element appearing in the least-significant bits of the result.
,value not guaranteed to be preserved: for example, a SInt of width 3 and value -1 (0b111) would become an UInt with value 7
chiselCloneType is called at the top-level of a clone chain.
chiselCloneType is called at the top-level of a clone chain. It calls the client's cloneType() method to construct a basic copy of the object being cloned, then performs any fixups required to reconstruct the appropriate core state of the cloned object.
a copy of the object with appropriate core state.
cloneType must be defined for any Chisel object extending Data.
cloneType must be defined for any Chisel object extending Data. It is responsible for constructing a basic copy of the object being cloned. If cloneType needs to recursively clone elements of an object, it should call the cloneType methods on those elements.
a copy of the object.
Return the binding for some bits.
Return the binding for some bits.
Creates an new instance of this type, unpacking the input Bits into structured data.
Creates an new instance of this type, unpacking the input Bits into structured data.
This performs the inverse operation of toBits.
what fromBits assigs to must have known widths
,does NOT check bit widths, may drop bits during assignment
,does NOT assign to the object this is called on, instead creates and returns a NEW object (useful in a clone-and-assign scenario)
Returns the width, in bits, if currently known.
Returns the width, in bits, if currently known.
java.util.NoSuchElementException if the width is not known.
Returns whether the width is currently known.
Returns whether the width is currently known.
Default pretty printing
Returns Some(width) if the width is known, else None.
Returns Some(width) if the width is known, else None.
Data type for representing bidirectional bitvectors of a given width
Analog support is limited to allowing wiring up of Verilog BlackBoxes with bidirectional (inout) pins. There is currently no support for reading or writing of Analog types within Chisel code.
Given that Analog is bidirectional, it is illegal to assign a direction to any Analog type. It is legal to "flip" the direction (since Analog can be a member of aggregate types) which has no effect.
Analog types are generally connected using the bidirectional attach mechanism, but also support limited bulkconnect
<>. Analog types are only allowed to be bulk connected *once* in a given module. This is to prevent any surprising consequences of last connect semantics.This API is experimental and subject to change
