Defined in:
lib/HDLRuby/std/sequencer_channel.rb

Overview

Creates an abstract channel over an accessing method. NOTE: Works like an enumerator, but can be passed as generic arguments and generates a different enumerator per sequencer.

  • +typ+ is the data type of the elements.
  • +size+ is the number of elements.
  • +access+ is the block implementing the access method.
