Answer Posted / manav rathi
function:
1:executes in zero stimulation time.
2:usually return a single value.
3:parameters of mode IN.
4:do not have wait statement.
5:function call state always concurrent.
procedure:
1:may or may not execute in zero stimulation time depending
upon whether it has wait statement or not.
2:may or may not retun a single value.
3:parameters of in,out or inout.
4:has wait statement.
5:procedure call statement may be cocurrent or sequential.
