Hardware Testing

Comprehensive Hardware Validation & Board Support Testing

Before safety-critical software is integrated, the underlying hardware must be proven reliable. We provide end-to-end Hardware Validation Services using custom-developed Test Software and Host-GUI interfaces to ensure every component on your PCB performs to specification.

we bridge the gap between complex hardware design and rigorous aerospace certification.

Our Testing Methodology: The Host-Target Approach

We utilize a sophisticated Host-Target architecture to automate and standardize the validation process:

  1. On-Board Test Software: We develop dedicated, high-performance test firmware that resides on the target controller (e.g., TMS570).
  2. Host GUI Control: A custom-built Graphical User Interface on a Host Computer drives the testing sequence via RS422/RS232 communication.
  3. Real-Time Diagnostics: The system executes a “Stimulus-Response” loop, reporting real-time status and clear Pass/Fail results back to the GUI for audit logging.

Peripherals & Interface Coverage

Our validation suites exercise the full capabilities of your hardware, ensuring that both on-chip peripherals and on-board communication controllers are fully functional.

1. On-Chip Logic & Memory Validation

We perform deep-dive testing of the microcontroller’s internal architecture, including:

  • Safety Features: VIM (Vectored Interrupt Manager) and PBIST (Programmable Built-In Self-Test).
  • Memory Integrity: Comprehensive R/W stress tests for SRAM, FRAM, and internal Flash.
  • I/O Control: Validation of GPIO, I2C, and SPI protocols for sensor and peripheral communication.

2. Aerospace Communication Controllers

Verification of mission-critical data buses to ensure zero-loss communication:

  • ARINC 429: Protocol validation, label filtering, and timing accuracy.
  • MIL-STD-1553B: Remote Terminal (RT) and Bus Controller (BC) functional testing.
  • USB & High-Speed I/O: Signal integrity and data throughput validation for external interfaces.

Why Choose Our Validation Services?

FeatureYour Advantage
Deterministic TestingOur custom test software runs directly on the hardware (TMS570), ensuring “bare-metal” accuracy.
Automated ReportingThe Host GUI generates automated logs, reducing human error and providing evidence for DO-254 audits.
Aerospace PedigreeWe understand the nuances of safety-critical chips like the TI Hercules series (TMS570) and avionics bus architectures.
End-to-End TraceabilityWe map every test case back to your hardware requirements, ensuring 100% verification coverage.
