Abstract
Engineering Change Orders or ECOs are all too prevalent in ASIC design. Unfortunately there are
few tools that directly support these “last minute” changes to a design. So it’s left to us humans to
figure out a solution.
This paper will cover the ad hoc solutions that have been developed for implementing ECOs.
Topics to be covered:
• basic definitions: the types of ECOs
• where in the flow to make the change
• advanced netlist dissection techniques
• implementing large ECOs using thousands of gates
• equivalence checking: your best friend
• back-end issues
• why ECOs are really a management problem, and how to deal with it |
