This must wrap the datatype used to set the io field of any Module. i.e. All concrete modules must have defined io in this form: [lazy] val io[: io type] = IO(...[: io type])

Items in [] are optional.

The granted iodef must be a chisel type and not be bound to hardware.

Also registers an Data as a port, also performing bindings. Cannot be called once ports are requested (so that all calls to ports will return the same information). Internal API.

TODO(twigg): Specifically walk the Data definition to call out which nodes are problematic.

Chisel2 code didn't require the IO(...) wrapper and would assign a Chisel type directly to io, then do operations on it. This binds a Chisel type in-place (mutably) as an IO.

Represents an eagerly-determined unique and descriptive identifier for this module

The desired name of this module (which will be used in generated FIRRTL IR or Verilog).

The name of a module approximates the behavior of the Java Reflection getSimpleName method https://docs.oracle.com/javase/8/docs/api/java/lang/Class.html#getSimpleName-- with some modifications:

- Anonymous modules will get an "_Anon" tag - Modules defined in functions will use their class name and not a numeric name

Disallow any more IO creation for this module.

Signal name (for simulation).

A generator of IO

Additional module prefix, applies to this module if defined (unless localModulePrefixAppliesToSelf is false) and all children.

Should localModulePrefix apply to this module? Defaults to true.

Users should override to false if localModulePrefix should apply only to children.

Should the localModulePrefix include a separator between prefix and the Module name

Defaults to true, users can override to false if they don't want a separator.

Called once the module's definition has been fully built. At this point the module can be instantiated through its definition.

The resolved module prefix used for this Module.

Includes localModulePrefix if defined and if localModulePrefixAppliesToSelf is true.

Legalized name of this module.

Takes the first seed suggested. Multiple calls to this function will be ignored. If the final computed name conflicts with another name, it may get uniquified by appending a digit at the end.

Is a higher priority than autoSeed, in that regardless of whether autoSeed was called, suggestName will always take precedence.

Returns a FIRRTL ModuleTarget that references this object

Returns a FIRRTL ModuleName that references this object

Returns a FIRRTL ModuleTarget that references this object, relative to an optional root.

If root is defined, the target is a hierarchical path starting from root.

If root is not defined, the target is a hierarchical path equivalent to toAbsoluteTarget.
