Wrapper¶

Wrapper is an abstraction over entities that have ports - examples include IP cores written in Verilog/VHDL, cores written in Amaranth and hierarchical collections for these that expose some external ports. Subclasses of this class have to supply implementation of property get_ports() that has to return a list of all ports of the entity.

class Wrapper(*args, src_loc_at=0, **kwargs)¶

Base class for modules that want to connect to each other.

Derived classes must implement get_ports method that returns a list of WrapperPort’s - external ports of a class that can be used as endpoints for connections.

__init__(name: str)¶

get_port_by_name(name: str) → WrapperPort¶

Given port’s name, return the port as WrapperPort object.

Raises:¶

ValueError – If such port doesn’t exist.

get_ports() → List[WrapperPort]¶

Return a list of external ports.

get_ports_of_interface(iface_name: str) → List[WrapperPort]¶

Return a list of ports of specific interface.

Raises:¶

ValueError – if such interface doesn’t exist.
