OrCAD Capture - Synchronize up on hierarchical part deletes new ports

D Campbell

Hello all,

I'm working on a schematic that has a lot of hierarchical blocks.  I've never messed with hierarchical blocks before in Capture so I might be missing something obvious.  I need to update one of these blocks but I'm running in to trouble when trying to synchronize the hierarchical block after I make change to it.  For example say I have a hierarchical block with a port named 'CS'.  I want to rename this port 'CS1' so I go to the schematic page and rename the port.  When I go to the hierarchical block, right click, and select 'Synchronize up' it will delete the 'CS' port but it doesn't add a 'CS1' port.  In the session log it says: 

Synchronize Up - Results
Source: SCHEMATIC:Voting_CC_MISC
INFO(ORCAP-2287): FAILED TO ADD: PORT: CS1, HBLOCK: Voting_CC_MISC - PAGE: TOP LEVEL - SCHEMATIC: SCHEMATIC1
INFO(ORCAP-2257): REASON: Unable to add due to space constraint at X: 0 - Y: 100
********** End of Results **********

I'm not exactly sure what this means.  It sounds like it's having trouble placing something.  I've tried resizing the box and various other things but none of those fixed this.  Does anyone know how to resolve this?

Thank you,

Dylan

    In case anyone else has this problem, I figured it out. OrCAD always tries to place the new port at the very bottom of the block. If you don't have space there it will give this error. I got unlucky because I only tried increasing the size on the top. What is weird is there was room on the bottom right but OrCAD wouldn't place it there.  Only on the bottom left.  But in another block I have it does the opposite(places the port in the bottom right instead of the bottom left.)
