Arria10 spread spectrum clocking

Hi, I need to implement spread spectrum in a PLL. I found this option in the ALTPLL IP, which is no longer available for Arria10. Is there something similar? I need a clock in the range of ~20-40MH...

    I was able to solve the problem. I connected the output clock of the PLL with the reconfig_clk0. This enables a glitch-free change of the C-counter.
