Cells of this type are u ``parallel cases'' (defined by using the {\tt parallel\_case} attribute or detected by an optimization). -The {\tt \$safe\_pmux} behaves similarly to the {\tt \$pmux} cell type. But when more than one bit -of \B{S} is set, it is guaranteed that this cell type will output the value of the \B{A} input instead of -an undefined value. - Behavioural code with cascaded {\tt if-then-else}- and {\tt case}-statements usually results in trees of multiplexer cells.
