What is difference between the pllena and areset signals available on Stratix and Cyclone series device PLLs? Which signal should I use to initialize the PLL?

Environment

  • PLL
  • BUILT IN - ARTICLE INTRO SECOND COMPONENT
    Description

    The functionality of pllena is the same as areset on all Altera PLLs. Both pllena and areset can be used to initialize the PLL. Pllena controls all PLLs in the device, while areset initializes the PLL on a per-PLL basis.
