XST - "WARNING:Xst:382 - Register <1> is equivalent to <2>"


During Low-Level Synthesis in XST, the following warning message occurs: 


"WARNING:Xst:382 - Register <1> is equivalent to <2>"


This message simply means that two registers in the design have been found to have the same functionality (clk, data, and controls), either directly in the HDL source or after logic optimization.  


XST can merge these two registers if the "Equivalent Register Removal" option is enabled.
