Update Layout after schematic modification

pitter

 I changed schematic connection (in schematic editor)  while drawing layout. Layout editor does not seem to notice the changes and an error is reported (wrong connection - yellow cross on the connecting metal path - short marker).A had this issue before, and it is pretty likely that LVS will fail, although schematic is OK. How to make layout editor update after making changes in schematic editor and not to draw short marker?

IC613, PDK - AMS

 Kind Regards,

pitter.

    Hi pitter,

    Your question is a bit unclear, so let me take a guess. If using Layout XL (or VLS XL in IC61), then you would need to do Connectivity->Update Components and Nets (and potentially a "check" operation on the schematic if you've not done so already). This doesn't happen automatically (because it would be really annoying to have it change half way through doing the layout, if you wer e only half way through making the schematic changes...).

    I didn't quite undefrstand what the "error is reported (wrong connection)" meant - what is giving the error? If the Layout Editor has not noticed the changes, how is it giving an error? Confused...

    Regards,

    Andrew.
