with a select b <= "1000" when "00", "0100" when "01", "0010" when "10", "0001" when "11"; When / Else Assignment The construct of a conditional signal assignment is a little more general. If d(i) equals 1, the If Statement increments num_bits. The num_bits variable is then assigned to the signal q, which is also declared in the Entity Declaration. For more information, see the following sections of the IEEE Std 1076-1993 IEEE Standard VHDL Language Reference Manual: Section 8.6: If Statement. Section 8.8: Loop Statement It’s a more elegant alternative to an If-Then-Elsif-Else statement with multiple Elsif’s. Other programming languages have similar constructs, using keywords such as a switch, case, or select.

We hardware engineers rarely use it in HDL. We hardware engineers rarely use it in HDL.

VHDL-93 defines an unaffected keyword, which indicates a condition when a signal is not given a new assignment: label: signal = expression_1 when condition_1 else expression_2 when condition_2 else unaffected ; In simulation the VHDL simulator will at startup assign a value of 'U' (unknown).
