ASTM F1888 SEE Testing of FPGA Devices Under Heavy Ion Irradiation
The ASTM F1888 standard defines a methodology to assess Single Event Effects (SEE) in Field-Programmable Gate Array (FPGA) devices subjected to heavy ion irradiation. This service is critical for ensuring the reliability and performance of electronic systems that operate in high-radiation environments, such as satellites, aerospace electronics, medical equipment, and nuclear facilities.
Single Event Effects occur when a single particle strike within an integrated circuit (IC) results in a transient or permanent change in its functionality. In FPGAs, these effects can lead to data corruption, logic errors, or even complete system failure. ASTM F1888 SEE testing provides a robust framework for assessing the resilience of FPGA devices against such events.
The test involves subjecting the FPGA device to heavy ion irradiation in a controlled environment. The ions are typically chosen based on their energy and mass properties that correspond to those found in the target application environment. Following exposure, the device's functionality is evaluated using standard logic analyzers or other diagnostic tools to identify any changes.
This service ensures that electronic systems designed for harsh radiation environments can operate reliably without unexpected failures. The ASTM F1888 SEE testing process not only helps manufacturers validate their products but also provides valuable insights into potential design improvements and mitigation strategies.
| Ion Type | Energy Range (MeV) | Mass (amu) | Fluence (ions/cm2) |
|---|---|---|---|
| Cobalt-60 | 3.5 to 7 MeV | 60 amu | 1E+13 ions/cm2 |
| Silicon-32 | 100 to 300 MeV | 32 amu | 5E+10 ions/cm2 |
The choice of ion type and energy is crucial for accurate testing. Cobalt-60, for instance, is often used for its relatively low energy and high fluence rate, making it suitable for quick screening tests. Silicon-32 ions are preferred for their higher energies, which more closely mimic the conditions in space or other high-radiation environments.
Once the device has been exposed to the specified irradiation parameters, it undergoes a series of diagnostic checks. These include measuring the device's output voltage levels, checking for logic errors using built-in self-test (BIST) circuits, and verifying the integrity of configuration data stored in non-volatile memory.
The results from ASTM F1888 SEE testing are highly valuable for both design engineers and quality assurance teams. Engineers can use this information to refine their designs, choosing more radiation-hardened components or implementing additional shielding measures where necessary. Quality assurance personnel gain confidence that the products they release meet stringent reliability standards.
ASTM F1888 SEE testing is a specialized service tailored to the unique requirements of industries dealing with high-radiation environments. By leveraging this standard, manufacturers can ensure their electronic systems perform reliably under challenging conditions, thereby enhancing overall product quality and customer satisfaction.
Scope and Methodology
The ASTM F1888 SEE testing process is designed to assess the vulnerability of FPGA devices to Single Event Effects caused by heavy ion irradiation. The methodology involves several key steps, each critical for ensuring accurate and reliable test results.
| Step | Description |
|---|---|
| 1. Device Preparation | The FPGA device is thoroughly cleaned to remove any contaminants that could affect the testing results. It is then mounted on a suitable holder for irradiation. |
| 2. Irradiation Setup | The device is placed in a vacuum chamber where it is exposed to heavy ions with specific energy and mass characteristics. The ion source used can be either a cyclotron or a LINAC (Linear Accelerator). |
| 3. Data Collection | During irradiation, various parameters are continuously monitored, including the number of ions delivered to the device and the resulting changes in its output signals. |
| 4. Post-Irradiation Analysis | The FPGA is tested for any changes in functionality or performance. This includes checking logic integrity using BIST circuits and verifying configuration data. |
The ASTM F1888 standard provides detailed guidelines on how to perform each step of the SEE testing process, ensuring consistency across different laboratories. By following these procedures, manufacturers can ensure that their products are robust enough to withstand real-world radiation environments.
It is important to note that the specific parameters for irradiation (energy and mass of ions, fluence) should be chosen based on the expected operational environment of the device. For instance, devices intended for space applications may require exposure to higher-energy ions compared to those used in terrestrial applications. This ensures that the test conditions accurately reflect the actual operating conditions.
The results from ASTM F1888 SEE testing are reported comprehensively, detailing any observed changes in the FPGA's behavior following irradiation. This data is invaluable for both design engineers and quality assurance teams, providing actionable insights into potential improvements or necessary enhancements to the device design.
