changing pll settings

I need to try a series of different phase delay settings on an internal (cyclone) pll. Do I have to re-synth and fit every time or is there a shortcut.

Which version of Quartus are you using? The chip-editor is a low-level representation of the silicon, so it originally didn't support the high-level things like phase shift(which affects many PLL settings and can be done in several ways). But there were enough people trying to do this that it should work in the latest Q7.1, and I believe in several previous releases.
