Schematic Navigator - cell list hierarchy is displaying like flattened post layout format

Sometime Schematic Navigator behaves differently by displaying cells in flattened post layout format. When clicked on any cell or net, it will not highlight in navigator. This will be very difficult to find particular net. I tried un-compress option. But didn't help.

    Can you go over the top of the Name column (the grey bar at the top) and do Right Mouse->View Name to enable the view name? My guess is that you have a config that is switching into a post-layout schematic extracted view (maybe from Calibre, since Quantus doesn't produce schematic views). It can't really invent flattened post-layout names, nor create 18,000 instances or 40,000 nets - the flattened data can only show in the navigator if it's actually flattened (i.e. it doesn't flatten the hierarchy itself).

    There was an issue where changing the config didn't get reflected in the navigator - they got out of sync in rare events - but I think (if my memory is correct) that this was fixed a while ago. Which IC sub-version are you using?

    I see my av_extracted view in View Name. Even after removing av_ext view from Environment Switch View List, I still see these flattened names.

    Virtuoso sub-version IC6.1.8-64b.500.26 (64-bit addresses)

    If you're not using a config view and just changing the switch view list in the ADE Setup→Environment form then the navigator in the schematic editor knows nothing about that. It will use the view list in the schematic editor Options→Editor form instead. Even then it doesn't refresh unless you descend and return (for example).

    Things are much better synchronised if you use a config view - that way both ADE and VSE know what your intent is for the hierarchy traversal, and both will stay in sync.

    So from what it sounds like, all is working as I'd expect.

    Thanks Andrew.
    av_extracted was still showing in the Schematic Options > Editor > View Name List. When I removed it, it works fine. Saved defaults & relaunched Virtuoso. But, av_extracted shows up in the list again. I don't see av_ext cdsenv file, don't know where is this saved.
    Created new schematic, copied old schematic cells into new one. New one works fine without av_ext view.

    If you look at your original schematic, can you do Edit->Properties->CellView in the schematic editor. Is there a property called viewNameList? If so, you might want to delete it... (you may need to reopen the schematic after removing the property to see the effect on the navigator).

    Thanks Andrew. Deleting av_extract from viewNameList helped. It's working now.
