The variability doesn't come from the process only but also EDA tools because some layout effects are too complicated to model. Moreover, the variability requires wide range of design margin which seriously hurt the production cost.
I have noticed that what happens in the foundry influence a lot. I would have liked this to come from the foundry consortium. There are many things that go wrong when a chip enters a foundry that modeling could just be a waste of time.
For this service to make sense you must be tied very closely to the foundry. There has been number of companies like PDF Solutions that have been offering yield enhancement service for years. What is different about GSS? Kris
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
