New ContributorDo reconfigurable integer PLLs support dynamic phase shifting in Arria V devices?
Hi Ash_R_Intel,
I am happy to report I finally managed to show the dynamic phase shifting working with my integer pll design. I changed my setup so I had three identical clocks coming out of my pll. On the scope, I triggered on the first clock and changed the phase of the other two clocks. I was able to easily see the change of phase after this. I took your suggestion on board of using values of 90 and 180 degrees to start. However, using a shift counter value of one repeatedly allowed me to see the clock phase changing.
I am going to close of this issue now. Thanks again for your help!!
New ContributorHi Ash_R_Intel,
thank you for replying to my query. I will try your suggestion of changing the phase shift values relative to 90 and 180 degrees. If that does not work I will try the fpll design instead of the integer pll I am currently using.
Thanks
