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.
