Allegro Module Mapping for Parallel components

markyd
markyd over 4 years ago

I'm wondering if these is a way to help the allergo "Place Replicate Apply" determine which components should be mapped for those in parallel.

The common example is capacitors, and although this doesn't create an electrical issue or problem, it's a bit aggravating for someone trying to keep refdes mapping consistent between pages.

Maybe an simple example:

My schematic are laid out in a way that has 4 parallel capacitors on two pages

Page 1: C10, C11, C12, C13

Page 2: C20, C21, C22, C23

Now let's say i layout and make a module of the 4 caps on page 1.   I want to create a replicate of the 4 caps on page 2 to map such that

C10 -> C20

C11 -> C21

C12 -> C22

C13 -> C23

However every time i replicate the mapping is random, sometimes Allegro guesses a couple the way i want:

C10 -> C20

C11 -> C21

C12 -> C23

C13 -> C22

Other times it's gets none the way i want:

C10 -> C23

C11 -> C22

C12 -> C21

C13 -> C20

Of course i can do the manually mapping myself and for small modules like this example it's no issue.  But for larger modules as i'm doing this is taking too much time.  Is there a way, maybe some property, that can be set to pre-map components or help it guess better?

    No property by there is another product that you can purchase called CircuitSpace that has much more control for design reuse and takes the schematic page into account. PCB Clustering for OrCAD | EMA Design Automation (ema-eda.com)
