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...

Thanks Anand,

Your are right, only one PLL is available for the chip I am using. There were two PLL from the 10M08 datasheet, but mine is just one.

So now, my question is how can I generate more than 5 clocks when only one PLL is available.

Is there any way?

what I want to try is generating 4 phase-shift clocks plus 2 more control clocks.

Similar one is here. Please look at Figure 2-18 on https://www.altera.com/en_us/pdfs/literature/hb/max-10/m10_handbook.pdf.

Please, give me help.

Thanks,
