Sending output pin to input pin in the other .bdf file

Well, there is this standard procedure.

Let me explain with an example. Suppose I have 2 circuits: a counter ( in any form: counter.v/counter.vhd/counter.bdf) & a comparator (again in any form comparator.v/comparator.vhd/comparator.bdf).

Now I wish to supply the output of the counter as a ramp input to the comparator, in order to generate a PWM.

procedure:

1) Open the counter file in Quartus II.

2) Go to file -> create/update -> create symbol files for current file

( this command will compile your counter circuit & save a symbol file called counter.bsf in your project directory)

3) Do the same thing with the comparator file.

4) Now, create a new BDF file, call it pwm_generation.bdf

5) Double-click anywhere inside to bring-up the symbol window. There click the '+' sign before 'project' where you will find your counter & comparator.

6) Just bring them together on this new block diagram file, and do the required input-to-output wiring ! That's it.

( You may also edit & customize the individual counter.bsf & comparator.bsf symbols to suit your connection routing )

Thank you for your reply.

But, how can I send the output pin to other .bdf file without a symbol file or the third .bdf file.

best regards

Hi,

let's try to clarify what you would like to achieve. I assume you have one BDF with , let say an output A. You will use this output A as input A in an other BDF. Right ?

As far as I know the only way to do this is described by "makontrack". The "connection" between the BDF's is described by the design hierachy. The lower level BDF's are always represented by symbols in higher levels.

Kind regards
