TestMAX Advisor

RTL Testability Analysis and Optimization

Synopsys TestMAX Advisor, built on SpyGlass® technology, performs RTL testability analysis and optimization, enabling designers to fine-tune RTL early in the design cycle to predictably meet manufacturing and in-system test coverage goals. The tool’s extensive design-for-test (DFT) rule checking and RTL fault coverage estimation capabilities pinpoint testability issues early in the flow (Figure 1) thereby enabling designers to avoid test bottlenecks downstream that can lead to time-consuming design iterations. TestMAX Advisor identifies areas in the design with hard-to-test ATPG faults and provides a report of test points to improve test coverage and reduce patterns and test costs.


  • Shortens test implementation time and cost by ensuring RTL or netlist is scan-compliant
  • Improves test quality by diagnosing DFT issues early at RTL or netlist


  • Lint checking and analysis for DFT
  • Connectivity and IP rule checks
  • Test Point selection for hard-to-test faults
  • RTL stuck-at and transition fault coverage estimation
  • Intuitive, integrated debug environment with cross-probing among views
