The
Libraries Guide for all primitives. In addition, VHDL and Verilog files are generated by the
Clocking Wizard in the ISE® software. The Clocking Wizard sets appropriate DCM and
single/parallel PMCD configurations.
The Clocking Wizard is accessed using the ISE software, in the Project Navigator. Refer to

button in each window.
GCLK
IOB
A dedicated local connection exists from the CLKA1D8 output of each PMCD to the
CLKA and CLKB inputs of the other PMCD within the same tile (group of two). Thus,
only CLKA1D8 can directly connect two PMCDs in series.
From the Project Navigator menu, select Project -> New Source. The New Source
window appears.
Enter a file name and select IP (CoreGen and Architecture Wizard).
Click Next. The Select Core Type window appears.
Select Clocking -> Single DCM_ADV, click next. The New Source Information window
appears.
Click Finish.
The Clocking Wizard starts.
