Scan test dft

WebSome techniques are very simple, such as supplying resets into a design. Without these, the test vectors must enact a homing sequence that brings a design into a known state such … WebTest compression is a technique used to reduce the time and cost of testing integrated circuits. The first ICs were tested with test vectors created by hand. It proved very difficult to get good coverage of potential faults, so Design for testability (DFT) based on scan and automatic test pattern generation (ATPG) were developed to explicitly test each gate and …

WebFigure 3.16 shows a scan chain in a sequential circuit design. The SFFs are stitched together to form a scan chain. When test enable signal TE is high, the circuit works in test (shift) mode. The inputs from scan-in (SI) are shifted through the scan chain; the scan chain states can be shifted out through scan chain and observed at the scan-out (SO) pin.
