Hi,
I always use ALTPLL of MegaWizard to create PLL for my design. But now, I use ALTMEMPHY for DDR interface. There is a PLL reconfiguration Interface and some pins that I am not clear such as: - pll_reconfig_write_param - pll_reconfig_read_param - pll_reconfig_counter_type - pll_reconfig_counter_param - pll_reconfig_data_in ... I have refered ALTPLL_RECONFIG user guide. But I hardly understand it. Can you explain me more. (what is purpose of these pins? If I set all of them default value (0), the PLL run well? ) Thanks for any help. I'm a new in PLL design.Link Copied
