XST 5 input mux synthesis question

Aug 25, 2004 1 Replies

Hi all,



2 questions. I am designing a 5 input mux with the following verilog

assign muxOut = (selectA) ? inputA : (selectB) ? inputB : (selectC) ? inputC : (selectD) ? inputD : E;



will xilinx know to put a 5 input mux there? How do i know if it did?



If I know that E is the latest arriving input is there a way to insure that XST puts it in the fastest path of the mux? Is there a fastest path in a 5 input mux?



Thanks



Matt
