Now currently there is a limitation that only the first 2 straps will be exported as power pads and so only those will get 'vias' from the top level. What I ended up doing is manually editing the LEF file to manually add the others ...

There is the met5. Some seems to be touching, can't tell though

yeah they are. That's probably because your macro is using

met5

and the wrapper doesn't expect it.

Sounds like i should try to match the offset and widths as well then?

How do you prevent a macros from using met5?

and align the macro so it hit

set ::env(GLB_RT_OBS) "met5 0 0 1500 500"

I think creates a routing obstruction in the given bounding box

In your macro in the end you will have no

met5

straps at all, so nothing to match.

(the

met5

straps will be generated at the wrapper level)

Now you can also take the alternative and still generate

met5

straps inside your macro and then 'align' them to the upper grid ... that should work too, just make sure to align GND with GND or you'll have a bad time 😅

okay cool. that is what i was going for. I would like to try both ways. I think the alignment would be nice
