luna_soc.gateware.core.timer module

A simple timer peripheral.

class luna_soc.gateware.core.timer.Peripheral(*args, src_loc_at=0, **kwargs)[source]

Bases: Component

class Counter(*args, src_loc_at=0, **kwargs)[source]

Bases: Register

A CSR register.

Parameters

fieldsdict or list or Field: Collection of register fields. If None (default), a dict is populated from Python variable annotations. fields is used to create a FieldActionMap, FieldActionArray, or FieldAction, depending on its type (dict, list, or Field).

Interface attributes

elementElement: Interface between this register and a CSR bus primitive.

Attributes

fieldFieldActionMap or FieldActionArray or FieldAction: Collection of field instances.
fFieldActionMap or FieldActionArray or FieldAction: Shorthand for Register.field.

Raises

TypeError: If fields is neither None, a dict, a list, or a Field.
ValueError: If fields is not None and at least one variable annotation is a Field.
ValueError: If element.access is not readable and at least one field is readable.
ValueError: If element.access is not writable and at least one field is writable.
