    LPDDR3 Routing: Strobe lines longer than clock lines on the same layer?

    noeliascotti

      Hello! I was analyzing the LPDDR3 routing with the Allegro Free Physical Viewer. I saw weird things...  There are strobe lines longer than clock lines, for example strobe0 836 mils and clock 413 mils on the same layer L4. I understand that max strobe length is clock length - 10 mils.

      There is one address line with 273 mils and another one with 434 mils on the same layer L2.

      I don't understand this, how is it possible?
