AND控制点类似，其原理与OR控制点相近，但具体电路结构略有不同，具体实现细节在此不再详述。观察点的插入遵循类似流程，以四输入与门输入端A0无法观测为例。在A0插入观察点后，电路调整，右侧SFF连接至扫描链。通过设置test_point_en信号至1，将A0值通过与门传递至D端的F0001，再将Scan_en信号置0，...
Analysis-driven test point insertion using TestMAX Advisor Flexible scan channel configurations to support multi-site testing and wafer-level burn-in Multiple compression configurations to support different testers and packages with different I/O Boundary scan synthesis, 1149.1/6 compliance checking and BSD...
Complete, Integrated DFT Solution Natively integrated with the Genus Synthesis Solution or standalone DFT insertion Compression Optimization Up to 2.6X reduction in compression logic wirelength—resolves routing congestion issues due to traditional scan compression logic ...
The technique re-uses the existing functional logic;\nas a result, the design-for-testability (DFT) overhead on area or timing\ncan be minimized. In this paper we show an algorithm which considers the\ntest point insertion for reducing the area overhead for the full scan\ndesign. We also...

Shift Left in DFT Design April 10, 2025 Tessent™ RTL Pro software automates the analysis and insertion of Tessent VersaPoint™ test point technology, LBIST-OST test points, dedicated scan wrapper cells and x-bounding logic as behavioral code at the RTL level. Tessent RTL Pro builds on ...
SLSC plug-in modules can operate in the chassis in three different modes: stand alone, pass through, or cascaded. Cascaded mode can be used to cascade the signal path through multiple SLSC modules and implement functionality like signal fault insertion. You can choose from a variety of third...
We recommend including TPI in traditional scan insertion flow when using a DFT Compiler. Some commands are added in script simply to define which instances are required for the test point insertion, then we insert scan chains using the original configuration. This flow is convenient for both desig...

Test point insertion (TPI) is a widely used technique for testability enhancement, especially for logic built-in self-test (LBIST) due to its relatively low fault coverage. In this paper, we propose a novel TPI approach based on deep reinforcement learning (DRL), named DeepTPI. Unlike ...
