Scumbria,

<It is not clear to me how you do affordable production test on a design without synchronous scannable storage elements. Could you elaborate?>

I am with you in thinking large async designs are not ready for prime time yet but a few years back I saw some very interesting work coming out of Caltech on this topic. These guys have done some very efficient designs but I wonder if these designs will ever be able to compete with MHz sells markets.

I don't know if they made much progress on this topic over the years. Don't even know if they have many answers for tools and production issues but if you are not familiar with that stuff it may be worth a look.

Chuck

Scumbria,

re:"It is not clear to me how you do affordable production test on a design without synchronous scannable storage elements. Could you elaborate?"

I guess i don't understand the question.

Are you implying it is not possible to test a digital design that has asynchronous elements.

Or are you commenting on the limitations of ATPG tools to achieve high fult coverage without exhaustive scan chains.

regards,

Kash
