Which is worst is that tools like Xilinx's ISE have internal templates that encourage its use. Every time an ISE user creates a new VHDL file or asks the tool to generate a testbench template the tool adds std_logic_arith. But, do you think this is bad? well is even worst. Some students reported problems using the real IEEE packages (numeric_std) with ISE 10.0 (no service packs applied, the problem went away after applying a service pack). > How do we get the message out? > This is hard, not even IEEE itself is doing anything. I think IEEE should demand the removing of such a claim (proprietary, wrong designed code that claims to be part of an IEEE standard, because this is what people interpret) Regards, SET -- _______________________________________________________________ Ing.
