The name of test item is not easy to understand.
E.g. TEST.PD.PHY.ALL.5 Receiver Interference Rejection
The R&D team may be familiar with the SPEC, but not with the CTS (Compliance Test Specification).
Understanding the test concept can help clarify the issue and make it more specific.
E.g. Verify if the UUT can correctly receive signals with added noise.
The name of test item is not easy to understand.
E.g. DisplayPort ID4.1 – Jitter Tolerance
The R&D team may be familiar with the SPEC, but not with the CTS (Compliance Test SPEC).
Understanding the test concept can help clarify the issue and make it more specific.
E.g. Confirm that the maximum allowed Data jitter is supported by the Sink DUT.
The name of test item is not easy to understand.
E.g. Wi-Fi Certified 7 test case 5.25.3
The R&D team may be familiar with the SPEC, but not with the CTS (Compliance Test Specification).

Parameters
Check Point
Expected Results
The check fails if the UUT does not respond with a Request message.
Parameters
Check Point
Expected Results
The observed error number must be less than the numbers defined in the field of Maximum Number of Allowable Bit Errors.
We provide the test conditions and criteria for your issue.
Parameters
Check Point
Expected Results
We provide the test conditions and criteria for your issue.
Parameters
Check Point
Expected Results
Scan through a range of TMDS_CLOCK to TMDS DATA skew conditions: Test skew points at least every O.1TBIT:
e.g. 0.0 TBIT, 0.1 TBIT…1.0 TBIT. If Sink fails to adequately support signal at any point, then FAIL.
Parameters
Check Point
Expected Results
Compare with another sample to determine if it’s a single-sample issue.
Compare with previous models that have already passed/certified.
In addition to identifying issues and error symptoms, we offer further support to help developers reach solutions more efficiently, including:
On-line, face-to-face, or inter-discuss with our experienced engineers who already execute hundreds/thousands of the same tests.
Conducting additional experiments (using additional tools/methods) to isolate or narrow down the possible causes of problem.
Applying a fix-try in a timing manner and providing instant verification results timely.
If there is a “known-fix” fit the problem exactly, we will definitely share it with your developer.
After identifying the root cause of the issue, we will conduct another round of verification specifically focused on the issue.
After the problem is resolved, reproducing the issue again is necessary to verify whether the fix is effective.
This process helps prevent new issues and ensures reliability.
1st : Regression testing based on the issues.
2nd : Regression testing based on the specific field, such as electrical, protocol or test groups.
3rd : Full regression testing.
Allion creates and manages your problem and bug history of your products in a more organized way. We provide:
Provide the reference models for comparison
Help clients to understand the issue distribution (e.g. Electrical, Protocol, IOP…)
Identify general problem types or frequent issues
Analyze the frequent issues by brands, OEMs or product types
Distribution trend analysis
