    Group,

    I am working on a way to backanotate from the schematic some parasitic
    values( with respect to the nets) without having to run extraction on
    the layout. I was able to gather the parasitic values of the net from
    the layout( and display them) by using ROD paths & grabbing the tech
    information. But in order to back annotae them to schematic i assume
    there should be connectivity knowledge in the layout & between
    schematic & layout
    I was able to get over the second problem( connectivity between
    schematic and layout) buy definging the same net names in both
    shcmetic & layout for the paths in concern, but i need to find a way
    to know connectivity in the lkayout

    I wondered how leHiMarknet is able to "recognise" connectivity for the
    layout, and would be grateful to know a rough algorithnm of how it
    works, SO i could incorporate in my skill program


    Thankyou
