Hi Lynn,

Am I wrong, or don't you work at a chipmaker there in Austin? Maybe Motorola, or maybe a smaller (perhaps boutique) chipmaker?

Lynn's profile says http://www.tekmos.com/

Tekmos is a fabless ASIC provider. We use our merged ASIC technology to create low cost ASICs.


In any case, you are making dangerous extrapolations based on a sample size of one.

Look at it this way: if someone bought one of your chips which happened to be somewhere at the upper end of the performance spread, "tested" it, then made a design based on those tests, would you honour your warranty on the chips from the lower end of the performance spread that failed to perform to his "test" results - even though they were still within your datasheet specs...?
