Design for Test and Test Coverage Analyzer

TestWay Express is an integrated DfT and Test Coverage Analysis software that enables designers and manufacturers to prevent and detect defects from design to production.

Test coverage analysis software
- TestWay Express operates from native CAD formats and is powered by QuadView visualization.
- Electrical rules checking enables the identification and rectification of electrical rules violations, before finalizing the board layout.
- Probe analyzer automates probe placement with a comprehensive set of rules to define priorities, clearances and constraints and generate detailed accessibility reports.
- The software simulates test strategies using test machine models to maximize test coverage and optimize test programs to minimize redundancy between strategies.
- The theoretical models estimate the test coverage of each individual stage (SPI, AOI, X-Ray, Boundary scan [BST], In-circuit [ICT], Flying probe [FPT] and Functional test) and optimize the combined results.
- TestWay Express generates the output files, aligned on the simulation results, for programming the assembly, test and inspection machines.
- By importing the post-debug test programs, test engineers can measure the actual coverage and compare this against the early estimation, to identify gaps in the overall strategy.
- twSystem is an add-on module to extend the PCBA viewing and analysis at system level.

Improve product quality
TestWay Express improves product quality by striving to detect and prevent all faults on a product. It analyzes the number of defects detected at each stage in the test process and identifies any shortfall in test coverage.
