`pdn` generates hanging unconnected piece of metal and `psm` doesn't like it

Open donn opened this issue 1 year ago • 3 comments

Describe the bug

Still toying around with mpl2 when this happened

Screenshot 2024-08-27 at 18 03 12

This VPWR strip doesn't have enough overlap to create a via and is thus just vibing there

Expected Behavior

That strip of metal should be culled unless I specify -skiptrim, no?

@gadfort thoughts?

maliberty avatar Aug 27 '24 16:08 maliberty

At present if a via fails to be created floating stubs are left behind which they should not, I'll take a look at fixing this issue this week

@gadfort did this get resovled?
