The Evolution and Challenges of PCIe Technology
PCIe (Peripheral Component Interconnect Express) technology is a critical interconnection technology in today’s computer systems, with high-frequency and high-speed characteristics that impose stringent requirements on system performance and reliability. With the introduction of new generation standards such as PCIe 5.0, 6.0, and 7.0, data transmission rates continue to rise, presenting even tougher challenges for electrical signal integrity and stability.
• High Frequency and Speed: Higher data transmission rates mean higher signal frequencies, which increases the demands on signal integrity and timing. The data transmission rates for PCIe 5.0 and PCIe 6.0 are 32 Gbps and 64 Gbps per lane, respectively, while PCIe 7.0 reaches up to 128 Gbps per lane.
• Diverse Applications: PCIe is not only used in traditional computer systems but has also expanded into consumer electronics, automotive, industrial, and other fields, each with varying reliability and stability requirements.
• Signal Complexity: High-speed transmission, various signal types, and complex encoding methods make the measurement of PCIe signals increasingly complicated.
Reasons for Essential PCIe Electrical Signal Measurement
• Ensuring Signal Integrity: PCIe signals are susceptible to noise and crosstalk during high-speed transmission, which can lead to decreased signal integrity and even errors.
• Early Detection of Potential Issues: Precise measurements can help identify and resolve potential problems, preventing failures or performance issues in actual applications.
The Importance of PCIe Testing Fixtures
To address the challenges posed by the development of PCIe technology, PCIe testing fixtures play a vital role. As tools to assist in the testing of PCIe products, they provide accurate and reliable measurement environments, ensuring the accuracy of test results.
• Providing a Standardized Testing Environment: Testing fixtures are designed according to PCIe standards, offering a compliant testing environment that ensures comparability of test results.
• Improving Testing Accuracy: Testing fixtures, paired with high-precision measurement instruments, can accurately capture PCIe signals, enhancing testing precision.
PCIe testing fixtures and electrical signal measurement are critical for ensuring the performance and reliability of PCIe systems. Through precise measurements, potential issues can be detected and resolved early, improving product quality and reliability.
Customer Challenges and Issues
Analyzing Customer Pain Points—Diverse PCIe Form Factor Testing Difficulties
The customer is a technology giant spanning the consumer PC and server sectors. To ensure superior performance and reliability of their products, they plan to establish a high-frequency PCIe testing environment internally. However, with the rapid development of PCIe technology and the diversification of the customer’s product line, they have encountered unprecedented challenges in testing after introducing the PCIe 5.0 specification.
Identifying the Problems:
- Form Factor Limitations: The current CEM standard test fixtures for PCIe 5.0 from the PCIe Consortium do not meet the customer’s diverse PCIe form factor requirements, such as M.2, U.2/U.3, EDSFF E1/E3, and OCP NIC 3.0. The lack of dedicated test fixtures for these form factors has hindered testing efforts.
- Testing Delays Due to In-House Fixture Development: Due to the lack of suitable testing fixtures, the customer has had to consider developing their own, which consumes significant time and manpower, severely affecting the product launch timeline.
- Inaccurate Testing Data: In-house developed fixtures may lead to inaccurate test data, failing to accurately reflect product performance and increasing risks after market launch.
- Increased Costs: Developing their own fixtures not only consumes R&D resources but also adds to overall costs.
Specific Needs Analysis:
The customer urgently requires a PCIe testing solution that can meet the following demands:
- Comprehensive Form Factor Support: The solution must cover various PCIe form factors, including M.2, U.2/U.3, EDSFF E1/E3, and OCP NIC 3.0, providing a one-stop testing fixture solution.
- Ensuring Product Quality: Appropriate test fixtures are needed to accurately measure the signal quality of products across different form factors, ensuring the accuracy of test data and maintaining market competitiveness.
- Cost Reduction: Avoid the costs associated with developing their own fixtures to lighten the financial burden.
Consequences of Not Effectively Addressing These Issues:
If the above challenges are not effectively resolved, the customer will face the following risks:
- Product Launch Delays: Inaccurate measurements will directly impact the product launch timeline, leading to decreased market competitiveness.
- Product Quality Issues: Inaccurate test data could result in performance or reliability issues in the market, damaging brand reputation.
- Increased Development Costs: Developing their own fixtures will raise R&D costs.
If these issues are not effectively addressed, the customer will encounter risks such as delayed testing progress, unguaranteed product quality, and decreased market competitiveness. Therefore, the urgent need for PCIe test fixtures that support multiple form factors is their greatest challenge.
