test vehicle
A circuit or IC designed for the purpose of evaluating one or many device characteristics.
NOTE 1 For the purposes of JESD89, the characterization is the soft-error sensitivity of a particular process technology, but the test vehicle can incorporate other structures used to characterize different parameters, such as yield, speed, voltage margin, etc.
NOTE 2 This test vehicle is not typically a product but is a dedicated component or section of an IC chip designed to be used in predicting the SER of a product.
