Module: Origen::TopLevel

Extended by:
ActiveSupport::Concern
Defined in:
lib/origen/top_level.rb

Overview

Include this module to identify it as a top-level object in Origen, normally an object that represents the SoC/Top-level device.

Origen will then fallback on this top-level object to service any register read/write requests or any pin requests that are generated by lower level objects and which cannot be fulfilled at that level.

The current top level object can then be referenced at any time via Origen.top_level.

def add_package(id, _options = {})
  p = ChipPackage.new
  p.id = id
  p.owner = self
  yield p if block_given?
  _add_package(p)
  p
end

#current_package(_options = {}) ⇒ Object Also known as: package

Returns the current package configuration of the pin owner, unless specifically specified by the application this will return nil.

def current_package(_options = {})
  if @current_package_id
    return _packages[@current_package_id] if _packages[@current_package_id]
    fail "The package #{@current_package_id} of #{self.class} has not been defined!"
  end
end

#current_package=(val) ⇒ Object Also known as: package=

Use this to specify the current package option for the given SoC.

This allows different pin configurations to be specified by package.

  end
end

#delete_all_packagesObject Also known as: delete_all_pkgs

Sets the Origen.top_level.packages array to nil. Written so packages created in memory can be erased so packages defined in Ruby files can be loaded
