Opening existing layout from schematic in XL using SKILL language

Hi Srimant,

Your question is quite vague. You can use Launch -> Layout XL (VLS-XL) from the schematic menu and choose "Use existing" and direct it to the correct layout. Now the layout has a connectivity source and references the schematic even if it comes from a different library or has a different cell name; if you open the layout in VLS-XL the schematic can open too.
If this is not really what you are looking for then provide more details so that folks have a clue as to what you are doing and what you want (and which version you are using, plus any other important details).

Best regards,
Lawrence.

Hi Lawrence,

In my case initially the layout was done from the schematic, where both schematic and layout views were present in same library.
But later on schematic views from that library got copied to some other library which is having only schematic views.(Designer will be using this new library for any update in schematic)
So in this case when I launch XL from layout, it opens the schematic from the same library(not from the new library).

So I am launching the existing layout from schematic of new library, where we have the option of choosing the library/cell/view.
But I want to skip all these manual steps(usage of GUI). I want a SKILL program which will serve the same purpose.

I hope my problem statement is clear to you.

FYI I m using virtuoso 6.1.6

Hi Srimant,

You might consider the following then, which sets the connectivity reference for the layout cellview using SKILL:

lxSetConnRef( 
  t_layLib 
  t_layCell
  t_layView 
  t_sourceType { CELLVIEW | NONE }
  [ ?schLib t_schLib ]
  [ ?schCell t_schCell ]
  [ ?schView t_schView ]
)
 => t / nil


Sets or unsets the connectivity reference for a specified layout cellview without opening the layout view graphically. You must specify the layout view and whether the source type is NONE or CELLVIEW. If the source type is CELLVIEW, you can specify the schematic cellview to use (by default it is set to the schematic view in the same library and cell). The function also saves the layout cellview, but only if had not been modified prior to lxSetConnRef being called.

Hopefully this is what you are looking for, or at least helpful.

Best regards,

Lawrence.
