Hello David , Sorry for the late reply , Actually I am trying to find is there any IP for FPGA for the clock division. I didn't find any sorry if i missed out too. From the clk division RTL output connected ALTCLKCTRL IP which is looks me connected to the buffer, but still iam worried adding flop in between the clock will add more jitter or skew.
