I need to output ornet not to results database but as an input layer to other operations (not net area ratio...).
To my knowledge, ORNET is not allowed to be used for any other operations. Ornet generates unmerged data and that kind of data is not usable by the other operations that you mentioned. Here is a link to an ornet_technote with some background on the history of ORNET in case you're interested.
If you would like to discuss the type of check you want to perform, there may be some folks reading this that could offer suggestions about how they handled similar situations.
Thanks for getting involved in the Calibre Community.
thanks for your link.
what I need to do is exactly what is reported on Technote (the case of metal1 connecting to metal2 through a via...) and what I did with other tool some years ago...
I need to select (and use) overlapping metal1 and metal2 only when they are on the same net.
Net Area Ratio select only polygons from first layer (metal1) but I need to complete path including also connected metal2.
I didn't know RDB capability. I'll try...
Here is a TechNote that describes AND operation between two polygons from the same net
And here is a similar TechNote that describes intersection of M1 and M2 with less than 2 vias
I'll be interested to know if these TechNotes help.
your references were very helpful.
I'm not using code examples as they are, instead it was an idea to create path of metal1 and metal2 using not the simple "or" .
in other words, I'm creating paths taking in account the vias on metals intersections just to select metals only if they are connected.
I'm doing some tests but partial results seems to be good.
I think Technote is a very helpful link (maybe search function could be improved ?)
Apparently this capability just doesn't exist in Calibre, but it would still be great if someone could offer suggestions for a workaround.
