MAX 10: using two ALTPLL

Is it possible using two ALTPLL from one clock source with 10M08D? I tried instantiating two PLLs. One has 5 clocks, and the other one has one clock. But I got an error message during synthesizi...

Hi,

You can generate max of 5 clocks from one PLL. Not more than 5 clocks.

Example in Figure 2-18 can be implemented for the 5 clocks.

Maybe you can design a logic for 1 clock out of 6 clocks(4 phase-shift clocks plus 2 more control clocks) check which one can be implemented easily.

Let me know if this has helped resolve the issue you are facing or if you need any further assistance.
