Can't Connect Wire to Part Pin [OrCad Capture]

UWJeff

Hey Guys,

 

I've used OrCad Capture a couple times before this for some small, single-chip designs, as well as other schematic software for much more complex layouts.  My current project is a three-chip solution include an Altera Cyclone III part.  My problem comes with part C of the Cyclone III part.  Both A and B don't suffer from this issue.  Basically, wires won't connect to any of the pins on part C - it looks as though the part is hovering over top of the wires, as if on a second layer.  I've attached a picture as reference.

 

Has anyone encoutered this?  Any idea on a fix?  I've attempted to create a new page, with no luck, even a new project with the same result.  I think it might be the library, but thought I would check here first.

 

Thanks for your time and help,

 

Jeff

 

Wiring Problem

     My suspicion is that you created the part segment off-grid or placed it off-grid.  Easy to do, hard to fix.

    Seems plausible - any tips for how I should start fixing this (or at least checking if this is indeed the case)?

     

    EDIT:  Have to manually move the pins in the library, but its connecting!  Thanks so much!

    I believe the problem is the grid mismatch between grids on schematic and grids for when the symbol was built.  Try reducing the grids in the schematic to something like 1/2 or 1/5 or 1/10 in Setup > Preferences.

    One thing that I always do to eliminate this issue (if you don't have access to the part library, as is the case with me) is to force the wire to snap to the pin.  Start adding the wire, then right click and then say "snap to pin".  This will snap the wire to the pin, even it it's off grid, like yours are.  We recently went through and updated all of our libraries so we wouldn't have this issue, but there was a while where this was becoming a problem.  I do it now out of force of habit.

    This sounds a VERY useful tip but my version of Capture (16.01) doesn't appear to offer "Snap to pin". I've searched the User Guide and can't find it there either. I must be missing something obvious...
