Hello magic mailing-list readers, I have posted magic version 7.3.0 on my website, at http://bach.ece.jhu.edu/~tim/programs/magic/magic7_3.html This version of magic, which I have given the status of PRE-ALPHA, fixes a known problem with magic and stacked contacts. Previous versions of magic can only handle stacked contacts by defining contact types between any three layers. In addition, magic generates "images" of each contact type on each plane connected by the contact, leading to a large number of layer types. Version 7.3 uses the same layer type on each plane, avoiding the generation of excess layer types. It does generate extra layer types to represent combinations of two contact types in the same plane, thereby allowing contacts which share the same plane (e.g., via and via2, sharing metal2) to occupy the same space. Magic 7.3 is hardly production-ready, but is provided for anyone who wishes to help out with the development and test drive it. I will continue to maintain, debug, and enhance version 7.2 while bringing version 7.3 up to par. Regards, Tim
