Continuous Assignments: Characteristics

1) Left-hand side (LHS) must be

a net data type

2) Always active: When one of the

right-hand side (RHS) operands

changes, expression is evaluated,

and LHS net is updated

immediately

3) RHS can be net, register, or

function calls

4) Delay values can be assigned to

model gate delays

wire adder_out = mult_out + out

/*implicit continuous

assignment */

is equivalent to

wire adder_out;

assign adder_out = mult_out + out
