Automated Testing for Embedded and Safety-Critical Systems
Accelerate validation across the entire development lifecycle with Synopsys TPT. Automate model-, software-, and hardware-in-the-loop testing, reduce test maintenance, and ensure compliance with safety-critical standards, so your teams can ship faster with confidence.
Your trusted
partner for test automation and software validation.
Synopsys TPT (Time Partition Testing) is a unified test automation platform for embedded control systems, enabling engineers to design, execute, and validate tests across all development stages—from model-in-the-loop (MiL) to full vehicle and system validation.
It supports model-based development environments such as MATLAB/Simulink and AUTOSAR, while enabling seamless transitions between virtual and physical testing environments. By separating test intent from implementation, TPT dramatically reduces maintenance effort and ensures consistency as systems evolve.
Reduce Test Maintenance Overhead
Separate test logic, expected behavior, and execution layers to keep tests stable—even as models and software change.
Accelerate Time to Validation
Automate test generation and execution across all stages to eliminate bottlenecks and shorten development cycles.
Ensure Safety and Compliance
Support ISO 26262, ASPICE, and safety-critical workflows with full traceability, coverage analysis, and reporting.
Increase Test Coverage and Confidence
Automatically generate intelligent test cases to close coverage gaps and validate edge cases early.
Enable Continuous Testing at Scale
Integrate with CI/CD pipelines and cloud environments to support continuous validation across distributed teams.
TPT enables engineers to design tests graphically or automatically generate them from MATLAB/Simulink, TargetLink, AUTOSAR, and C/C++ models. These tests can then be executed seamlessly across MiL, SiL, PiL, HiL, ECU, and full system validation stages.
Its three-layer architecture — separating stimulation, expected behavior (Assesslets), and test logic (Testlets) — ensures that test intent remains stable even as implementations evolve. This dramatically reduces maintenance effort while improving reuse, consistency, and long-term scalability of test suites.
Ensure functional consistency as systems transition between development stages by executing identical test scenarios across environments and automatically comparing results.
TPT enables engineers to validate equivalence between MiL, SiL, PiL, HiL, and real or virtual ECUs, helping identify regressions, timing differences, and environment-specific behavior early—before they become costly issues at later validation stages.
TPT integrates with leading requirements and ALM tools such as DOORS, Polarion, and Codebeamer to provide full traceability from requirement to validation.
Test cases can be directly linked to requirements, enabling automatic generation of traceability matrices and clear visibility into coverage. This ensures compliance with standards like ISO 26262 and ASPICE while improving audit readiness and verification transparency.
Measure and achieve structural coverage metrics including MC/DC, decision, condition, and statement coverage to meet safety-critical requirements.
With intelligent test generation using TASMO and Silver, teams can automatically close coverage gaps and achieve near-complete validation for virtual ECUs. Built-in reporting and review workflows support rigorous safety processes aligned with ISO 26262 and ASPICE.
TPT supports full automation through its Python 3 API, enabling integration with CI/CD tools such as Jenkins and scalable cloud-based testing environments.
Teams can automate test execution, manage large datasets, and implement continuous testing strategies—ensuring validation keeps pace with modern, fast-moving development workflows.
Synopsys TPT is widely used across industries where embedded software performance, safety, and reliability are critical, supporting validation workflows from early development through full system testing.
Synopsys TPT enables continuous validation across the full development lifecycle, from model-based design and virtual ECU testing to hardware-in-the-loop (HiL) and bench-level system validation.
Synopsys TPT integrates seamlessly into existing Ansys environments, extending simulation-driven design into automated system validation and testing.
For teams already using Ansys tools for physics-based design and safety analysis, TPT bridges the critical gap between requirements, system behavior, and verification:
TPT enables teams to move from requirements definition → system design → control validation → full system verification,
ensuring that safety-critical systems are not only designed correctly, but proven under real-world conditions.
