a VHDL error
Hi;
I want to use some symbols as delay time for signal assignements. So I use the following lines for this purpose:
constant Tbuff : integer:=5;
constant Tcable : integer:=7;
begin
a <= b after Tbuff +Tcable;
but I receive these error messages when I compile them. Would you please help me to resolve this errors?
ERROR:"Operator "+" is not defined for such operands."
ERROR:"Time expression expected."
Regards
