The best way to learn the tool is to start using it, go through the tutorials, get some training from Cadence, use the web....

  • Re: Auto routing in Allegro16.0
    Specctra reads in a dsn file (either directly or in the background like from Allegro) which contains all the physical database info (nets, components, padstacks, placement), then it also uses do files to set up things like rules, routing etc. When you go to Specctra from Allegro it automatically creates a dsn file and do files so that ...

  • Re: Duplicating Placement for Indentical Group of Circuit
    Again, it's so simple you'd laugh. Unfortunately I will not give out the solution but once you figure out how to tag the items in the schematic and layout (extremely simple!!! -- look into user properties) this becomes a snap.
