pat, << a typical design cycle >> Once an agreement is reached for a new design, a team is formed with representivies from design, marketing, test eng., product eng, and management. Usually it's lead by the designer and reviewed by all monthly. Every step of the cycle is identified and completion dates are established using project management. If your not familiar with the project management process, well, it's a coarse in itself. Designs may take typically 6 months to a year, depending on resources, priority, and complexity. Usually a 2nd pass effort is planned in to fine tune anomalies found on the 1st pass. Once 1st pass is completed, fab processing will be about 4 - 6 weeks depending on process complexity. Test programs can now be debugged by testing actual devices. In parallel devices can be sent to the customer for their evaluation. A 2nd pass design tune-up, so to speak, usually occurs. 4 - 6 more weeks. If product meets specifications, a qualification of the device muse be started, intense work to make test programs able to test 100% of the design is under way. If the qualification is successful on 1st pass that's about 7 weeks. Any failures must be evaluated and either design or process fixes put in place. Another cycle for the product. The complexity is so great one always wonders how it's ever successfully completed. It's easy to go on and on, but maybe this will give a rough idea of what it takes from the drawing board to the product. Most design houses like Amati, haven't a close clue to the effects of parasitic components created with the actual chip architecture. They can't see problems beyond their ideal world of schematics. And on and on and on! Larry
