Virtuoso keeps changing to "any angle" when descending to a lower layout level.

kenc184

I find when I pop down a layout hierarchy, or when first opening a  layout, the usual default of "orthogonal" is not selected. Whether it's a move or a copy or a stretch, I find it has changed to any angle. I have never edited the .cdsinit, so there's nothing there to override the default.  I seem to be spending way too much time hitting F3 and changing to orthogonal.  For three years it hasn't been this way!  I've tried restarting a cadence session but to no avail.

Version IC6.1.8-64b.500.27    Any ideas?

  • In the library manager, use the context (right mouse button) menu over the library name, and select "Properties". On the resulting form, see if there's a hierarchical property called viewProps. This will have "EXPAND" next to it, and on the popup form may have maskLayout and another EXPAND button. If you expand that, you may be seeing settings for various things, including segSnapMode and snapMode. These come from having used the Save To button on the Options→Display in the layout editor. You might also want to check the technology library too. 

    It could also be saved to the cellView (although then that would not be affecting the cellViews down the hierarchy). If it's the cellView, you'd see it via File→Properties (properties tab) in the layout editor for each cellView.

    The idea is that cellView supersedes library supersedes techLib supersedes cdsenv var.
