@1@2 in XOR not working with my LYP file

rambir

Hi All,

When I ran XOR and no .lyp file, klayout shows me @1 and @2 postfix on the layers to differentiate between Layout1 and Layout2.
I do not see the same when I have layers file loaded. Is there a workaround to see the layers with @1 and @2 foreach source layout?

Here is the properties section of my lyp file.

Hi Rambir,

the .lyp file does not show up properly - you should use mark down code formatting when pasting such code (use a line with triple backticks before and after the code).

There is a secret feature which allows embedding dynamic information inside the name. This will add the "@x" layout index:

<name>M1.drawing - 1/0@$(C+1)</name>

Explanation:

• "$..." will include a formula (KLayout expressions syntax) which is evaluated and inserted
• "C" is a dynamic variable containing the zero-based layout index
• "C+1" will give you the 1-based layout index
• Hence "$(C+1)" will expand to "@1", "@2" ...

There are more variables available:

• "N": the layer name (OASIS, DXF, CIF ...)
• "L" : the layer number (OASIS, GDS2)
• "D": the layer datatype
• "I": the layer index from the layer source (the internal database layer number) - hardly useful for normal applications
• "C": the layout index ("cellview index")
• "S": the layer view's source string
• "T": the layout's title (usually the file name)

If you don't want to modify the layer properties file you can also use "Regroup/By Layout Index" from the layer list's context menu. This will give you separate trees for "@1" and "@2".

Kind regards,

Matthias

Hi Matthias,

Thank you very much for this one.. Everything you do helps a lot.
Is it possible to have this feature automatic while converting from CDNS techfile to lyp? We can also change it by a postscript i understand..?

wish you a wonderful day ahead.

Thanks & regards

Hi Matthias,

Thank you again, I could change it in the import_tf routine and it worked very well as well.
