final class Analog extends Element

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.

Note

This API is experimental and subject to change

    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.

    returns
