Differential Pair routes with No Gap

Korey

Hi,

I'm using OrCAD PCB Designer and have created differential pairs. When I manually route the pair, the gap between traces is always zero no matter what I set the gap to in the contraints manager. I'm fairly new to this tool so I'm getting a littel frustrated why it does this. I even found another posting that some provided a .brd design with a diff pair and its own CM settings. When I deleted the traces to then reroute them, I found the same problem, the trace gap went to zero! Is this a license limitation or am I missing something? I've created CSet spacing parameters in the CM.

Thanks for any help that someone might be able to provide.

     You are running the base release from the DVD. I would recommend getting the latest hotfix

    For prosperity's sake, I make this entry for anyone who may referance this in the future. Version 16.5 inital base release has had 54 patches since its release and customer support informed me that the diff. pair min spacing don't function with this base release (go figure). and this is why it's grayed out.

    Thank you to all that fielded this problem and helped to find a the solution. The collective brain will always out weigh a single entity :-)

    Best Regards,
