Hi,
In vhdl I create many times entity is like below:
entity HALFADDER is
port(
A, B : in bit;
SUM, CARRY: out bit);
end entity HALFADDER;
When I want to use this port into another bigger file
(for example a full-adder ) I need in VHDL to
create a component from it.
This then looks like
component HALFADDER
port(
A, B : in bit;
SUM, CARRY: out bit);
end component;
Notice that only the first line and the last line changes:
entity HALFADDER is
becomes
component HALFADDER
and
end HALFADDER;
becomes
end entity HALFADDER;
This entity to component changing happens rahter often.
Say that you copy the 5 lines of the entity and then
paste them where you want to use it as component.
Is it then easy to replace the first and last line of these 5 lines of
entity code to 5 lines of component code by pressing i.e. F5?
If so how to do this?
Rgds,
Eric
