AVL Testing and Validation FAQ

What is DRAM testing?
There are many types of DRAM tests but most can be organized as either pre or post production tests. Pre-production testing involves the validation and qualification tests that verify compliance to specifications and prescribes standards.

Why is testing and validation important?
Validation testing ensures that designs are compliant and serves as a "known good point" for suppliers and manufactures. It helps reduce costs and time to market.

How much does it cost?
Validation tests differ in price range based on specific requirements, but generally they run from about $1000 to $1500 per test. For more information, contact us.

Who is using validation type services?
All OEM's, DRAM suppliers, and chip manufactures go through a validation process prior to production or commercial release.

How long does it take?
Validation generally takes about three days, but can take longer based on additions to the test suite.

What happens after the testing or validation?
The results of the test are communicated to the requesting agency and the conforming modules are posted on a dedicated web site for publication and reference.

Is the validation a controlled process?
The validation process is a controlled process from beginning to end. The process is often predetermined by industry standards or customer protocols. For more information about AVL's process, click here.

What qualifies AVL to do such high grade testing?
With its extensive engineering expertise AVL has performed over 1000 validation tests for PC OEM's, DRAM suppliers and chip manufacturers. Intel and Rambus have certified AVL to independently perform these validation services.

What type of testing is required for validation?
Various types of tests are part of the validation process; temperature testing, power testing, functional tests and stress testing.

What specific tests are conducted?

There are several tests that comprise the validation suite, they include;

  • Ambient temperature testing
  • Functional stress - read write patterns
  • AC power cycling
  • SPD check
  • Power management / S3 testing
  • Thermal stress testing
Are these the only tests that AVL performs or offers?
No, AVL supports many different tests and services. General services and capabilities include both standard and custom test routines.

Is there any special equipment required?
Yes, AVL administers the tests with the latest test equipment and supports an in-house machine shop for mechanical fabrication to support various test bench configurations.

Do engineers perform and control the testing?
Yes, AVL conducted tests are administered and controlled by dedicated engineers.
