Error (15629): Atom "comb~0" is dependent on unconnected input ports - Error (15629): Atom "comb~0" is dependent on unconnected input ports Description You may see this error when instantiating an Altera_PLL_RECONFIG megafunction in your Qsys system. Resolution Change the following settings in the .qsf for your project: set_global_assignment -name SYNTH_TIMING_DRIVEN_SYNTHESIS OFF set_global_assignment -name ADV_NETLIST_OPT_SYNTH_WYSIWYG_REMAP OFF set_global_assignment -name PRE_MAPPING_RESYNTHESIS OFF Related Articles Error (15629): Atom comb~6 is dependent on unconnected input ports Error ID 15629: Atom lcell_inst is dependent on unconnected input ports Why are the fPLL C counters not updated correctly when dynamically reconfiguring an Altera_PLL using the Altera_PLL_Reconfig IP?
