Duty Cycle Select settings are described in Table 9-6.

PLL Usage in IPexpress™
IPexpress is used to create and configure a PLL. The graphical user interface is used to select parameters for the
PLL. The result is an HDL model to be used in the simulation and synthesis flow.
Figure 9-8 shows the main window when PLL is selected. The only entry required in this window is the module
name. Other entries are set to the project settings. Users may change these entries, if desired. After entering the
module name of choice, clicking on Customize will open the Configuration Tab window as shown in Figure 9.
Note: PHASE/DUTY_CTNL is selected in the GUI ‘PLL Phase & Duty Options’ box and if it is set to ‘Dynamic
Mode’, then both DPHASE[3:0] and DDUTY[3:0] inputs must be provided. If one of these inputs is a fixed value,
the inputs must be tied to the desired fixed logic levels.
