Intel: How can I use ALTPLL's Source-Synchronous mode feature to synchronize a clock with specific input data?

Clock/PLL

This is possible by applying constraints in the Assignment Editor.
 
The setting method is shown below.
 
1. Start Assignment Editor
2. Register the input data you want to synchronize in the To column
3. Select "PLL Compensation" in the Assignment Name field
4. Select "On" in the Value field
5. Select "Yes" in the Enable field
 
After compiling, from Fitter ⇒ Resource Section in the compilation report,
Select PLL Summary and check if the pins registered in Compensated inut/outpu pins are assigned in the corresponding PLL.
