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.

Copies a Java resource containing some text into the output directory. This is typically used to copy a Verilog file to the final output directory, but may be used to copy any Java resource (e.g., a C++ testbench).

Resource files are located in project_root/src/main/resources/. Example of adding the resource file project_root/src/main/resources/blackbox.v:

addResource("/blackbox.v")

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).

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.

Returns a FIRRTL ModuleTarget that references this object
