Generate rate ports for variable-rate CIC filter


'off' (default)

Do not generate rate ports.


Generate rate and load_rate ports. When the load_rate signal is asserted, the rate port loads in a rate factor.

Usage Notes

AddRatePort is specifically for use with variable rate CIC filters. A variable rate CIC filter has a programmable rate change factor. It is assumed that the filter is designed with the maximum rate expected, and that the Decimation Factor (for CIC Decimators) or Interpolation Factor (for CIC Interpolators) is set to this maximum rate change factor.
