Recently in Compliance Testing Category

The MCCI USB-IF Compliance Test Lab has recently revised its price sheet. Three of the most commonly performed tests have gone down in price. These are the tests for:

  • High Speed Device with a Single Mode
  • High Speed Host System (includes 1-4 ports)
  • OTG High Speed
The cost of testing a High Speed Hub (1-4 ports) has been slightly increased, however, to cover higher-than-expected resource costs.

All other prices remain the same.

One question we are often asked is, "How long will the testing take?" The answer to this question can lead to very different consequences depending on the vendor's schedule. If the device is expected to go on the market within the next year, then the answer is merely logistical. However, if the device is expected to go to market next week, then testing at this point is a leap of faith, simply because there is no guarantee that the device will pass. Time for debugging must be a factor in test scheduling.
   
The process of obtaining USB-IF certification can be difficult, but not just because of the specification requirements. Often developers uncover problems not related to USB compliance during certification testing. For this reason, it can be helpful to test as early as possible, preferably well before the product is scheduled to be released. Of course, it is not always possible to test early, either because product requirements are in flux, extensive debug is necessary, or even because final hardware is not available. It occurred to us here at MCCI that it might be helpful for us to outline some tests that engineers can perform on their USB products in advance of those products entering the Compliance Lab. Using them may help flush out compliance problems during normal, pre-test development.
 
The tests we are recommending are tests that most consumer electronics product engineers should be able to perform with a small hardware investment and as little overall cost to their test budget as possible. After all, with the economic environment being what is, anything we can do to help companies avoid extra test costs or delayed market releases is for the best. Some of these tests we're going to tell you about come from the USB-IF compliance test suite, while others are our original work. Regardless, it is our hope to help you achieve USB-IF compliance for your USB product.
MCCI CEO Terry Moore will participate in a Roundtable Discussion on the Role of Software in System-Level Verification at the Santa Clara Convention Center on Tuesday, March 30. Other participants include Frank Schirrmeister (Synopsys), Shabtay Matalon (Mentor), and Bill Neifert (Carbon). Ed Sperling, Editor-in-Chief of  System-Level Design Community, will publish a transcript of the proceedings in that forum within two weeks of the event.

Here's an abstract of the theme under discussion:

The ongoing shift of project efforts from hardware to software in the era of multiple processor cores on a chip has significant impact on verification itself. More and more developers report that they use software on the embedded processors to verify the surrounding hardware. It is not only co-verification of hardware and software, the techniques to verify both seem to cause a melting process between both worlds of verification at the system-level. This roundtable will explore the role of software for verification and analyze the impact it will have on verification going forward.

MCCI Endorses LeCroy Test Equipment

"MCCI has relied on LeCroy's USB test equipment for years," remarks Terry Moore, MCCI CEO. "Throughout the process of developing the MCCI USB DataPump® for SuperSpeed, we will again look to LeCroy to provide easy to use equipment with advanced features like graphical Bus Utilization reports that allow our engineers to maximize performance of our USB 3.0 stack."

The USB Implementers Forum today announced that MCCI has completed the Wireless USB (WUSB) Testing Audit and is now fully authorized to test WUSB products, including WUSB Native Devices, WUSB Device Wire Adapters (DWAs), and WUSB Host adapters. WUSB Host adapters in scope include Native Hosts compliant with the Wireless Host Controller Interface (WHCI) specification, Host Wire Adapters (HWAs), and systems with embedded Hosts that use certified silicon. Look for MCCI on the USB-IF's Independent Test lab page as an authorized Test Lab for wireless products.
MCCI is now an independent test laboratory for next-generation Wireless USB products. Until now, WUSB products were certified through attendance at USB Compliance Workshops (a.k.a. "Plugfests") or at Intel. Testing is available for products in the following categories: Host Wire Adapter (HWA) and Device Wire Adapter (DWA) end products, as well as native host (WHCI) and device end-products.
