I/O Buffer and Dynamic Delay Integration

Intel recommends that you use the ALTIOBUF IP core to utilize the I/O buffers for any purpose that includes:

  • LVDS interfaces—using the ALTLVDS IP core, enabling dynamic delay through Intel® Quartus® Prime Setting File (.qsf) statements
  • DDR interfaces—using the ALTDDIO_IN, ALTDDIO_OUT, ALTDDIO_BIDIR, ALTDQ, ALTDQS, and ALTDQ_DQS IP cores
  • Dynamic on-chip termination (OCT) control—using the ALTOCT IP core
