Unknown Shapes on pins

Hi All,

I was wondering if anyone could explain the triangle shapes I'm seeing on the pins in the attached picture. They are attached to only two pins of one package and I can't find out what they signify. The other pins of this part do not have the shapes but they are the same padstack, so it isn't something there. I can find no properties or DRCs or anything associated with the pin or the net or anything. They are definitely associated with the pins, because I have to have the copper pin turned on for them to show up.

While I don't think they are causing me problems, I want to know what they are to be sure. I'd appreciate anybody who can shed some light on this for me. Thanks!

Trianlge Shapes on Pins

These triangles represent differential pair driver pins. The Diffpair Driver Pins feature was added in 16.3.

To enable driver pin display:
Choose Setup > Design Parameters > Display.
In the Enhanced Display Modes area, enable Diffpair Driver Pins.

For more information, refer to Allegro PCB Editor: What's New in 16.3 on Cadence Online Support:
