STIL Capture™

STIL Capture is a highly automated tool flow which trivializes the process of producing a well-structured STIL ATE program from a functional verification scenario. STIL Capture allows engineers to record in-STIL from any mixed-language simulation and verification environment, greatly enhancing controllability, ease of use and communication between teams.

STIL Capture Flow
STIL Capture Flow

STIL Capture removes the ad-hoc, error prone process of continuous translation of vectors between verification and ATE, allowing engineers to control STIL generation straight from simulation. Features include:

  • Capturing of event-based vector data in mixed-language simulation / verification
  • On-the-fly test vector data cyclization
  • Support for multiple waveform tables
  • Precise, event-driven, run-time controllability for test-program generation
  • Transaction annotation of STIL test programs

Unique Features

  • Easily control STIL generation to best support ATE needs and performance
    Parameterization,
    runtime control and on-the-fly Wave generation are made easy, directly from the verification environment
  • Transaction Annotation
    Produce structured STIL with functional verification information embedded in Pattern, PatternExec, PatternBurst, and other language constructs
  • Press-of-a-button delivery of DFT-based test cases
    Combine STIL generation with DFT verification to drive DFT-based simulation scenarios directly to ATE and accelerate silicon debug applications
Benefits
  • Higher quality ATE programs and test engineering flows
    Leverage built-in runtime STIL generation control features for more reliable generation at the source. Avoid excessive translation steps and intermediate data formats.
  • Enhanced Design Productivity
    STIL Capture features Automated Functional Test generation leading to improved Design to Test transition and organization collaboration.
  • Metric-Driven Functional Test
    Functional test is widely used in the industry but still relies on ad-hoc, experience-based test selection and lack of metric-based operation. STIL Capture creates a direct bridge from Verification to Test, allowing engineers to use rich metric-based test quality and applicability grading to drive ATE functional test generation.
