[PCB_FORUM] Re: Is there a way to step and repeat placement for identical circuits on the same PCB?

Hi Jean-Charles,

I am using DxD as my schematic front end.

Suggestion 2 is interesting, thanks.  My schematic sheets are identical for
all four copies of the circuit, and the REFDESs are "identical" as well.
For example, all REFDESs are in a format APXX where A is the REFDES prefix,
for resistors R etc., P is the page number, and XX is the "instance" number.
For example, the same component on sheets 2 & 3 would be R203 & R303.  What
someone else suggested is to place one copy of the circuit, export the
placement file, update the REFDESs and the locations (by a fixed offset),
and import...and that should place the next instance of the circuit.

Regards,

Austin
