Table 4.   IOPLL IP Core Parameters - Dynamic Reconfiguration Tab
Parameter Legal Value Description
Enable dynamic reconfiguration of PLL Turn on or Turn off Turn on the enable the dynamic reconfiguration of this PLL (in conjunction with PLL Reconfig Intel® FPGA IP core).
Enable access to dynamic phase shift ports Turn on or Turn off Turn on the enable the dynamic phase shift interface with the PLL.
MIF Generation Option 3 Generate New MIF File, Add Configuration to Existing MIF File, and Create MIF File during IP Generation Either create a new .mif file containing the current configuration of the I/O PLL, or add this configuration to an existing .mif file. You can use this .mif file during dynamic reconfiguration to reconfigure the I/O PLL to its current settings.
Path to New MIF file 4 — Enter the location and file name of the new .mif file to be created.
Path to Existing MIF file 5 — Enter the location and file name of the existing .mif file you intend to add to.
Enable Dynamic Phase Shift for MIF Streaming 3 Turn on or Turn off Turn on to store dynamic phase shift properties for PLL reconfiguration.
DPS Counter Selection 6 C0–C8, All C, or M Selects the counter to undergo dynamic phase shift. M is the feedback counter and C is the post-scale counters.
Number of Dynamic Phase Shifts 6 1–7 Selects the number of phase shift increments. The size of a single phase shift increment is equal to 1/8 of the VCO period. The default value is 1.
Dynamic Phase Shift Direction 6 Positive or Negative Determines the dynamic phase shift direction to store into the PLL MIF.
3 This parameter is only available when Enable dynamic reconfiguration of PLL is turned on.
4 This parameter is only available when Generate New MIF File is selected as MIF Generation Option.
5 This parameter is only available when Add Configuration to Existing MIF File is selected as MIF Generation Option.
6 This parameter is only available when Enable Dynamic Phase Shift for MIF Streaming is turned on.
