    Fixing Transition violations Reply

    1. I was trying to fix transition violation using -drv, for  a design with fences and guides. But I was in wain.  Once I removed them

    and recreated the encounter database with DEF, and V. The encounter was able to fix them.

    2. I removed the fences and groups using encounter (from floorplan menu) and saved the database. But some thing was blocking it to fix the transisition. The '.tran" file read something to do with "setDoAssign" ? 

    But go through the flow, I had to again, exit and recreate the database.

    Did any one experience such a thing.  What I am doing wrong here.

    Thanks a lot in advance for your help !!

    Regions and fences can really restrict optDesigns options so my default is generally placeDesign > unplaceAllGuides > optDesign.

    You might also need to add setOptMode -bufferAssignNets true.
