The chip manufacturing process is prone to defects and the defects are commonly referred as faults. A fault is testable if there exists a well-specified procedure to expose it in the actual silicon. To make the task of detecting as many faults as possible in a design, we need to add additional logic; Design for testability ...

WebIn our design, we instantiate a library clock gating cell ("DLSG1") to do functional clock gating at the RTL level. This cell has an SE input which is left unconnected in the RTL code since no other DFT signals are present at this stage: module my_cg (input clk, input enable, output clk_gated); DLSG1 u_cg (.C (clk), .E (enable), .SE (), .GCK ... WebMay 9, 2003 · DFT tools from EDA vendors can be used to generate at-speed scan vectors with good coverage. These tools allow two types of at-speed testing: transition delay testing and path delay testing. Both work …
WebJun 3, 2004 · At-speed clocks. An at-speed test clock is required to deliver timing for at-speed tests. There are two main sources for the at-speed test clocks. One is the external ATE and the other is on-chip clocks. … WebJan 12, 2024 · On-chip clock controllers To facilitate early validation, DFT can be implemented at the RTL phase of design. This enables validation and easy debug of the interaction of the DFT logic, typically with Verilog simulation which is much more efficient than gate-level validation.

WebOn-chip Clock Controllers (OCC) are also known as Scan Clock Controllers (SCC). OCC is the logic inserted on the SOC for controlling clocks during silicon testing on ATE …
WebFeb 26, 2008 · The logic lets TetraMAX® ATPG control every capture pulse on a per-pattern basis. The PLL and on-chip clock control for this core were part of the top-level clock control logic and were placed outside the core boundary. Conclusion. Table 2 shows the area used by the DFT logic compared to the total standard logic in the design.
