Ports and Parameters

The ALTPLL IP core ports and parameters are available to customize the ALTPLL IP core according to your application.

The options you select in the parameter editor affect the ports and parameters settings of the IP core. Most of these options are device-dependent, and some options depend on one another. The options you select enable the PLL features, and some might generate top-level ports in the ALTPLL IP core.

The following figure shows the top-level ports of the ALTPLL IP core.

The parameters are only relevant if you bypass the parameter editor GUI and instantiate the IP core directly in your design. The details of these parameters are hidden from the parameter editor.
