WebNov 24, 2024 · Design for Test (DFT) is, in essence, a step of the design process in which testing features are added to the hardware. ... As DFT will inevitably introduce a degree of additional logic, a physical design engineer will also need a strong impression of what DFT measures are planned from early in the process in order to begin incorporating it ... DFT techniques have been used at least since the early days of electric/electronic data processing equipment. Early examples from the 1940s/50s are the switches and instruments that allowed an engineer to "scan" (i.e., selectively probe) the voltage/current at some internal nodes in an analog computer [analog scan]. DFT often is associated with design modifications that provide improved access to internal circuit elements such that the local internal state can be co…
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 that testing can actually begin. More typically it includes the introduction of scan-based testing, built-in self-test (BIST) or increased observability using JTAG.
