Table 10-1: Legal left-hand forms in assignment statements Statement type Left-hand side ---------------------------------------------------------------------------------------------------- Continuous assignment Net or variable (vector or scalar) Constant bit-select of a vector net or packed variable Constant part-select of a vector net or packed variable Constant indexed part-select of a vector net or packed variable Concatenation or nested concatenation of any of the above left-hand sides ---------------------------------------------------------------------------------------------------- The coverage of this subject is a little indirect.
