DataPortInterface class

An interface to a simple memory that only needs enable, address, and data.

Can be used for either read or write direction by grouping signals using DataPortGroup.

Constructors

DataPortInterface(int dataWidth, int addrWidth)
Constructs a new interface of specified dataWidth and addrWidth for interacting with a memory in either the read or write direction.

Properties

addr → Logic
The "address" bit for a request when en is high.
no setter
addrWidth → int
The width of addresses in the memory.
final
data → Logic
The data sent or received with the associated request.
no setter
dataWidth → int
The width of data in the memory.
final
en → Logic
The "enable" bit for this interface, enabling a request.
no setter
hashCode → int
The hash code for this object.
no setterinherited
ports → Map<String, Logic>
Maps from the Interface's defined port name to an instance of a Port.
no setterinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited

Methods

clone() → DataPortInterface
Makes a copy of this Interface with matching configuration.
conditionalDriveOther(Interface<DataPortGroup> other, Iterable<DataPortGroup> tags) → Conditional
Makes this conditionally drive interface signals tagged with tags on other.
inherited
conditionalReceiveOther(Interface<DataPortGroup> other, Iterable<DataPortGroup> tags) → Conditional
Makes this signals tagged with tags be driven conditionally by other.
inherited
connectIO(Module module, Interface srcInterface, {Iterable<DataPortGroup>? inputTags, Iterable<DataPortGroup>? outputTags, String uniquify(String original)?}) → void
Connects module's inputs and outputs up to srcInterface and this Interface.
inherited
driveOther(Interface<DataPortGroup> other, Iterable<DataPortGroup> tags) → void
Makes this drive interface signals tagged with tags on other.
inherited
getPorts([Iterable<DataPortGroup>? tags]) → Map<String, Logic>
Returns all interface ports associated with the provided tags as a Map from the port name to the Logic port.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
port(String name) → Logic
Accesses a port named name.
inherited
receiveOther(Interface<DataPortGroup> other, Iterable<DataPortGroup> tags) → void
Makes this signals tagged with tags be driven by other.
inherited
setPorts(List<Logic> ports, [Iterable<DataPortGroup>? tags]) → void
Adds a collection of ports to this Interface, each associated with all of tags.
inherited
toString() → String
A string representation of this object.
inherited
tryPort(String name) → Logic?
Provides the port named name if it exists, otherwise null.
