Single schematic, multiple PCB layouts

#1 Post by mbelectronicdesign » 02 Apr 2020, 09:03

I have a client who wants me to take a single (simple 3 Op Amp) schematic and lay it out in 9 different ways on the same PCB for manufacture and evaluation purposes - mainly testing to get rid of a crosstalk issue.

I could copy the design sheet 8 times but is there any way to either:
1. Put multiple schematics onto the same PCB
2. Or create multiple PCBs from the same schematic and them merge them into a single PCB Gerber?

Or any other suggestions that achieve my aim?

Thanks in advance.

Ted

yes, given such simple circuit the easiest way i found doing something like this is

1. create the schematic for one circuit block (3 op-amp)
2. convert to PCB and place components and finish block layout

now you are done with one block

3. switch back to schematic, select everything that makes up the block
5. right click > Group, you can also hit Ctrl + Alt + G. this will group all components into a block not required but helps move block easily
4. now select the group, Edit > Copy Matrix 3 column / 3 rows or whatever suits you. This copies the block 9 times
5. SAVE schematic Important!!

switch back to PCB
6. select everything and group components press Ctrl + G
7. select the group, Edit > Copy Matrix 3 Column / 3 Rows this will copy 9 blocks

now just need to sync PCB to schematic ..

8. File > Renew Layout from Schematic > By RefDes

VERY important, you must renew By Refdes to maintain blocks placement / layout

now you can freely change individual block placement/layout to get your variation

good luck :)

Wow! That works as you described it. One detail nit pick is that step 6 should be...

6. select everything, right click and select Group (or press Ctrl + G)

It was also VERY useful to select (in my case) 1 column and 9 rows with 0 mm column shift and 26 mm row shift because, in my PCB, I'd done 1 layout at the top and it then placed the other 8 below it at 26 mm spacing which is exactly how I wanted it. The copies were in the right place with no further work :D

Thanks.

Awesome! Glad to help.
Thanks for the correction, Ctrl + G is to group and Ctrl + Alt + G to un-group
I have edited my answer above with correction
