In Virtuoso layout tool, you can zoom in to the selection
(leZoomToSelSet). Is there a comparable schematic editor command
function? |

In IC61, you have this - it's the SKILL function schHiZoomToSelSet().
For IC5141 you could use this code. Just call abZoomSel().

I am not on the new Cadence right now, so I needed your custom
function.
Thanks Andrew, it works beautifully! |
