Hey guys,
Do you have any trouble in very large netlist processing, include debug, trace, modification, ECO? I recommend you a free software, GOF, Gates On the Fly, is a graphical netlist trace and modification tool. It allows users to draw and isolate gates in schematics by just clicking on gate pins. Starting from one cell user has interest in, after several mouse clicking and moving, one circuit appears. Users can
move, replace, delete or add gates in the schematics, and can also drag
and drop gates from codeview window. After changes are made with the tool, an ECO file in tcl format or a new netlist file an be generated and printed. Go to the website
formatting link
and take a look. better be quick, otherwise the free trial will be gone.
