Abstract
An integrated circuit device () can include a main portion () and a built-in self-test (BIST) portion () having outputs coupled to physical input structures (e.g., bond pads) () of the integrated circuit device (). A BIST portion () can test timing critical parameters that take into account the effect of input structures (). A BIST portion () can apply BIST test signals with a pipeline structure that can emulate timing parameters, such as a set-up time (Ts) and a clock-to-output time (Tco).
