2. REPORT DETAILS
-----------------
BUFC-1#1 Warning
Input Buffer Connections  
Input buffer I_MEM_WAIT_IBUF_inst has no loads. An input buffer must drive an internal load.
Related violations: <none>

DPOP-1#1 Warning
PREG Output pipelining  
DSP SYS70/W11A/DPATH/MUNIT/DOUT0 output SYS70/W11A/DPATH/MUNIT/DOUT0/P[47:0] is not pipelined (PREG=0). Pipelining the DSP48 output will improve performance and often saves power so it is suggested whenever possible to fully pipeline this function.  If this DSP48 function was inferred, it is suggested to describe an additional register stage after this function.  If the DSP48 was instantiated in the design, it is suggested to set the PREG attribute to 1.
Related violations: <none>

DPOP-2#1 Warning
MREG Output pipelining  
DSP SYS70/W11A/DPATH/MUNIT/DOUT0 multiplier stage SYS70/W11A/DPATH/MUNIT/DOUT0/P[47:0] is not pipelined (MREG=0). Pipelining the multiplier function will improve performance and will save significant power so it is suggested whenever possible to fully pipeline this function.  If this multiplier was inferred, it is suggested to describe an additional register stage after this function.  If there is no registered adder/accumulator following the multiply function, two pipeline stages are suggested to allow both the MREG and PREG registers to be used.  If the DSP48 was instantiated in the design, it is suggested to set both the MREG and PREG attributes to 1 when performing multiply functions.
Related violations: <none>

RTSTAT-10#1 Warning
No routable loads  
1 net(s) have no routable loads. The problem bus(es) and/or net(s) are I_MEM_WAIT_IBUF.
Related violations: <none>
