dropping in exact part (different pin labels) without re-routing?

You create the second device, (the B item), in the library as it will have

a different part number. When you place that device in the schematic the

correct package appears on the board., displaying the desired labels.

Hi,

 

I have PDIP two parts, say, A and B, both of which have exact pin

count and footprints, etc. Their IO pins are different. I created a

schematic and routed BRD file with part A. Now, how would I substitute

part A for B to the schematic without doing the routing of the traces

again on my BRD file? The traces are the same, except the labeling.

You generate two library devices which have the same PACKAGE, i.e. the

same footprint and (important!) the same pad names.  If they are in the

same library, just use the same package; else, copy the package to the

new lib.

When you just delete Part A in your schematic and then insert Part B,

(only) the last segment of your traces to the part will be ripped up and

have to be rerouted.

When you REPLACE it in the board, you will have to choose whether to

reconnect the same pin names or the same pad names — in your case, the

latter.  No ripup and rerouting then.

HTH, Hans

Sorry, that was simply wrong.  One should look it up instead relying on

a old grey storage…

Do create your part B with exactly the same PACKAGE (so the board will

not be changed) and a SYMBOL that may have different pin names, but has

its pins at the same spatial coords as part A (copy part A's symbol and

only change the pin names).

Then, in your schematic, REPLACE part A by part B, choosing “same

coords”.  Done without ripup and rerouting.
