class	ChannelSignaling

class	ChannelType
	Channels are the basic communication primitives. More...

struct	Constant

class	Context

class	Instance
	Subclass of `HWModule` which represents a submodule instance. More...

class	IntegerType
	Integers are bit vectors which may be signed or unsigned and are interpreted as numbers. More...

class	UnknownWriteChannelPort
	Instantiated when a backend does not know how to create a write channel. More...

class	VoidType
	The "void" type is a special type which can be used to represent no type. More...

class	WriteChannelPort
	A ChannelPort which sends data to the accelerator. More...
