Tessent® Scan™ inserts scan test structure into a netlist, delivering design that is completely ready for scan testing and pattern compression.
Tessent Scan generates and adds the most effective scan architecture for your design, ensuring high-quality test with automatic test pattern generation (ATPG). It performs scan flop replacement and stitching, analyzes your circuit for possible test limitations, does test-related design rule checks (DRCs), and automatically corrects errors.
Features and Benefits
- Works within any tool environment to improve test quality
- Provides intelligent scan insertion and connection at all levels of design hierarchy
- Supports Mux-DFF, Clocked-Scan, LSSD, and mixed design styles
- Performs extensive design rules checking to identify testability trouble spots early in the design cycle
- Automatically corrects many common testability problems
- Supports layout-based scan ordering for optimal chain layout.
- Inserts IEEE 1500-compliant test structures to enable block-based testing strategies for SoC designs.
Tessent Scan facilitates ATPG with TestKompress and FastScan by generating the required input dofile for these tools.
Tessent® TestKompress® is the industry-leading ATPG tool that provides the highest quality scan test with the absolute lowest test cost. TestKompress has an industry-proven ATPG engine that applies effective fault models to the entire logic design. Manufacturing test costs are held in check by an award-winning test pattern compression technique called Embedded Deterministic Test (EDT).
