Honored ContributorHi,
Due to the internal implementation of PLLs in Altera FPGA (at least for Cyclone) devices, duty cycle, phase shift, and so on, are not software programmable. You only have the ability to modify them at design time. Take a look at the Cyclone device manuals, they have included very usefull information about this subject.
