TestWay Express is a fully integrated solution that enables electronic manufacturers to optimize the design to test and the new product introduction flows. Test is essential for improving product quality by striving to detect and prevent all faults on a product. This maximizes the number of good products shipped to the customer. TestWay Express analyzes the number of defects detected at each stage in the test process and identifies any shortfall in test coverage and undetected defects. It allows the computation of the IPC metrics such as first pass yield (FPY), fall-of-rate or escape rate by importing the real time DPMO (Defect Per Million Opportunities) from the manufacturing process. The manufacturing test strategy is tuned to provide the optimal test coverage for identifying potential defects.

  • Design for Component 
    When the key components are selected, check the ROHS, reliability, defects per million opportunities (DPMO), boundary-scan description language (BSDL) file validation in order to guide component selection.
  • Electrical Design for Test
    When the schematic sheets are defined, TestWay verifies the testability by conducting electrical rules checking that reflect the Design for Test (DfT) guide lines. These can include standard and customer’s specific checks relating to company requirements.
  • Test point saving
    By simulating the test strategy prior to the layout phase, TestWay helps to minimize the need for physical accesses that are necessary to detect defects aligned to the defect universe. It helps to reduce test point access by 30% to 70%!
  • Select manufacturing strategy
    TestWay estimates test coverage using theoretical models that reflect the capabilities for a wide range of test and inspection strategies, such as: Automated Placement Machines (APM); Automatic Optical Inspection (AOI); Automated X-ray Inspection (AXI); Boundary-Scan Test (BST); Flying-probe Test (FPT); In-Circuit Test (ICT) and Functional Test These models should be tuned to reflect the test and measurement capabilities of each individual target tester.
  • Test for Excellence
    Once the test and inspection programs have been debugged and released, it is imperative to be able read the completed test program or test report and compare the coverage between the estimated and measured analysis.
  • Functional test coverage
    Manage functional test as part of the overall test strategy, produce accurate coverage reports that assists the diagnosis of faulty boards in production and repair centers.
  • Test Probe Analyzer
    When the layout is finalized, test probe placement should be optimized according to test strategy definitions. The probe access information can then be used for estimating the test coverage, modeling the cost and calculating the production yield and TL9000 initial return rates.
  • Design to Build and Design to Test 
    TestWay exports CAD data in the native format useable by Assembly machines, Automated Optical Inspection, Automated X-Ray, In-Circuit testers, Flying probe testers and Boundary-Scan testers that is aligned to the simulated strategy. The exported files may include assembly and test programs, input lists, test models, as well as test fixture files used by the target testers. Any files created at the Design to Test stage can significantly reduce the downstream test development and fixture costs.
  • Test for Designability – Test is an important contributor for design improvement, once a feedback loop between production and design has been established, such as a concurrent engineering approach to design and test.
  • Board & CAD visualization
    Visualize test coverage and customer specific attributes in schematic, layout and netlist navigation views. This New-Generation Viewer also provides unique digitization feature that creates schematic view from PDF.
  • twDocumentor for shop floor documentation
    A powerful document management tool that allows quick and easy creation of comprehensive shop floor documentation, as well as the formatting of testability analysis reports.
  • Advanced reporting
    Produce comprehensive reports in a variety of formats that highlight predicted production yield, test coverage by component type, predict placement time, etc.
  • Cost modeling
    Predict test execution times, total engineering time and calculate hardware costs such as; test fixture, power supply, spring probes, wiring and vector-less sensors etc.
