@W:MT462 : mux_arbit.vhd(52) | Net RCU_DEC_0.U1_MUXARBIT.rcu_data4 appears to be an unidentified clock source. Assuming default frequency. 
@W:MT462 : mux_arbit.vhd(58) | Net RCU_DEC_0.U1_MUXARBIT.un1_rcu_data4 appears to be an unidentified clock source. Assuming default frequency. 
@W:MT532 : mux_arbit.vhd(50) | Found signal identified as System clock which controls 81 sequential elements including RCU_DEC_0.U1_MUXARBIT.rcu_data[31:0].  Using this clock, which has no specified timing constraint, can adversely impact design performance. 
@W:MT530 : apb_to_dcs.vhd(139) | Found inferred clock Trigger_receiver_v1_7_FCCC_0_FCCC|GL2_net_inferred_clock which controls 1007 sequential elements including apb_to_dcs_0.timeout_cnt_en. This clock has no specified timing constraint which may adversely impact design performance.
