Can anyone help me as to what should be the correction? How to explain the existence of just one religion? x x) has a type, then is the type system inconsistent?

Why are planets not crushed by gravity? Tried to put it into process but it dont works too. If and when Xilinx would support synthesis of conditional signal assignment statements within a process (as sequential signal assignment) is a matter of versions and/or policy. In above example I get no synthesis error and the my circuit works with both versions.

I reformatted your second code posting to allow the error to show up a bit easier. Hdlparsers:164 If you update the output outside a process, asynchronously, the update will take place as soon as (+tpd) at least one of the signals on the right hand of the assignment You will easily find most of your mistakes.
