Hi, Xiaoqiang
You may refer to below:
Warning (14285): Synthesized away the following RAM node(s):
Warning (14320): Synthesized away node "nios_mem_if_ddr2_emif_0:mem_if_ddr2_emif_0|nios_mem_if_ddr2_emif_0_s0:s0|rw_manager_ddr2:sequencer_rw_mgr_inst|rw_manager_generic:rw_mgr_inst|rw_manager_core:rw_mgr_core_inst|rw_manager_di_buffer_wrap:di_buffer_wrap_i|rw_manager_di_buffer:rw_manager_di_buffer_i|altsyncram:altsyncram_component|altsyncram_uok1:auto_generated|q_b[8]"
The q_b[8] may be not in usage, and therefore it is synthesized away.
Warning (169202): Inconsistent VCCIO across multiple banks of configuration pins. The configuration pins are contained in 2 banks in 'Internal Configuration' configuration scheme and there are 2 different VCCIOs.
The configuration pins have to be at the same voltage level, may be you need to check if the VCCIO of all the configuration pins are at the same voltage level. Alternatively, you can allocate all the configuration pins under one IO bank which has one voltage level.
Thanks.
