10/27/2021, 9:21 PM@User @User We have brought up our design (temp sensor using openFASOC) and the chips are alive! We are currently automating the testing. I had an additional question regarding the 100 bare dies we get. Is there control over the process centering? can we have skewed corners (i.e. SS, FF, TT, SF, FS). See below 🙂

11/02/2021, 2:15 PM@User thanks for getting back to me on this. We always or most the time receive skewed corners when it makes sense for our design (i.e. sensors or voltage refs etc..) it helps with characterization and calibration. I am not sure why it would cost a lot though. Thanks for checking!
