    Hi,

    I am hoping to do some manhattan routing of metals on a design using Nazca, specifically the interconnect module to simplify things. The constraints on the manhattan routing are that paths must be straight and intersect orthogonally (at 0 or 90 degrees) and/or at a 45 degree angle. Is this possible with the interconnect module??

    I have written custom cell functions to generate components of this sort but as you can imagine, dense routing becomes very tedious/difficult this way.

    Thanks!

    Hi Lumico,

    Manhattan routing is what you get when you connect pins that are multiples of 90 degrees for most interconnects. Avoid cobra_p2p(), bend_strt_bend_p2p(), vipers and mambas. There are ways to restrict sbend() or sbend_p2p() angles to 45 degrees with the Amax keyword.

    To understand your question better, would you have a picture on what you would like to achieve or expect and what you get?

    Maybe you refer to routing groups of waveguides?

    Hi Ronald,

    is there an easy way to define such a corner (Manhattan routing) using interconnects? Please see the attached image.

     

    Thanks in advance!
