  • Differential pair without DRC
    Hi,   I am trying to route a differential pair with two different track widths. They are 10mils when differential and become 14mils when they are single traced. There is always a DRC when the single traces come together to become a pair, as seen in the image. I am setting the differential pair track width in the constraint manager, and ...

  • Re: Routing differential pair with same length
    Yes, that's what I thought. I will just have to rearrange the components or figure it out.  Thanks!!

  • Re: Routing differential pair with same length
    Hi, Thanks for your help, it is not quite the solution I was hoping for.  The trace loops back on itself, and I am trying to figure out how to have them equal lengths while keeping the same distance from each other across the whole trace. Maybe there is no automatic or eloquent solution for ...

  • Routing differential pair with same length
    I am trying to route a differential pair, but I am having trouble making each trace the same length. Is there an easy way to do this in allegro?

  • Re: Changing grid size
    I'll look at the physical constraints and see if it works. Thanks

  • Changing grid size
    I am trying to place two differential signal lines close together, 8 mils between them. But due to the spacings between the grid points I cant measure the distance between the two traces accurately enough. Is there a way to make the grid size smaller?
