Virtuoso XL 6.1.5.500.9 opens physConfig along with schematic

Steve,

I don't really understand what you mean (what's the "non-XL schematic" for a start?). The physConfig is needed because the schematic has to know what configuration is controlling it - this contains all the rules for hierarchy expansion and view switching and so on (much as a normal config is used for simulation purposes) - even if the physConfig gets discarded when you close everything (i.e. if you never ran Configure Physical Hierarchy and saved the results).

So you always have to have a physConfig.

Hi, Andrew.  Thanks for the response.

 When I say non-XL schematic, I mean a schematic that is opened up Virtuso Schematic Editor L without being linked to Virtuoso Layout Suite XL.  No connectivity, just a schematic opened for viewing.  When I do that, the title bar says

"Virtuoso Schematic Editor L Reading: [library name] [cell name] schematic Version:[#]-Checkedin".

  When I open Virtuoso XL and attach a schematic to it, the title bar says

"Virtuoso Schematic Editor L Reading: [library name] [cell_name] schematic  Config:[library name] [cell name] physConfig Version:[#]-Checkedin".

So XL opens up a schematic with physConfig while a plain schematic without XL connectivity just opens up a schematic.  My problem is that sometimes, particularly after a circuit designer (I'm layout) makes an edit in a schematic, and after I do a library update, I can see the edit if I open the schematic by itself without XL, but when I use XL, the schematic/physConfig view does not show the edit.  Shouldn't the two match?  Since the XL layout is linked to the physConfig,  it's a problem when I'm not seeing the most recent changes in that view.  How can we do things differently such that I can see schematic edits whether or not I have VIrtuoso XL connectivity?

Thanks.
Steve.

Steve,

The schematic is the same schematic, regardless of whether it is opened with a physConfig or not - all that affects is how the hierarchy will be traversed - and how VLS XL understands which physical view will be used for each instance, and so on. The actual schematic should not be affected - as I said, it's exactly the same schematic.

I think you should contact customer support over this - it might be something odd to do with the design management you're using (the Version: [#] Checkedin bit is nothing to do with Cadence).

Regards,

Andrew.

Thank you, Andrew!

 That's great to know.  Thanks for pointing me in the right direction.  I should probably contact our local experts here and let them take a crack at it first.

 Have a great day.

 Steve.
