In this episode of Chalk TalkHD Amelia chats with Bob Potock (Kozio) about how you can save yourself a bunch of headaches at prototype time and how Kozio’s VTOS (Verification and Test Operating System) can solve all of your embedded design prototyping problems.
An environment for functional testing, peeking and poking memory, bus discovery and a powerful scripting because today’s embedded hardware design tools do not address the design test and verification process for prototype hardware, hardware engineers are forced to resort to in-house tools or application OS based testing, resulting in poor test coverage. This paper presents a new hardware test and verification process, based on a Verification and Test OS (VTOS™). VTOS is a user configurable test platform, requiring no porting and can be testing new prototype hardware in 30 minutes. VTOS provides an environment that includes functional tests, peeking and poking memory mapped locations, bus discovery and a powerful scripting language.
The production and distribution of counterfeit parts is rising and finding their way into consumer and military devices. As counterfeiters get more sophisticated, so must the tests used for detecting counterfeit parts. A functional test strategy can provide an additional detection methodology that will exercise the device under a variety of operating conditions exposing functional deficiencies. This paper will discuss how establishing a functional baseline will define the bar for functional performance and can be very effective in detecting and stopping counterfeit parts from being shipping in assembled electronic devices. It describes how Verification and Test OS (VTOS™) provides an extensive functional test library that can be easily extended or modified to create an operational baseline to be used to detect counterfeit parts. VTOS can be used in engineering, as well as manufacturing, providing test consistency while in search for counterfeit parts. If functional testing is missing from your test strategy, now may be the time to reconsider its benefits.
Learn how quickly and easily you can run a comprehensive memory test and uncover design and reliability issues. In this video, a memory failure is detected only in "burst" mode, while passing all other tests. A second development board passes all the tests.
Watch this short video on Embedded Design Verification Best Practices and learn how to verify embedded designs for correctness and reliability utilizing a NEW approach employing a Verification and Test OS (VTOS™).
Troubleshooting and quickly isolating faults is of tremendous value for reducing the time to redesign or repair failing boards. This process can cost a company millions of dollars each year. Supporting OMAP, Sitara, QorIQ, PowerQUICC and PowerPC, this paper describes how using an interpreter that allows the execution of a full test suite for verifying a design or an individual test for fault isolation can dramatically improve quality and reliability with Kozio’s Verification and Test OS (VTOS™). It describes how memory errors can be isolated to ECC (Error Control Coding), single-bit, row, column, and correlated to a part’s reference designator.
In this whitepaper the author reviews how leveraging VTOS during the prototype phase can assist engineers in overcoming the challenges design complexity exerts on product development, manufacturing, and overall time-to-market. Readers will gain insight into how they can replace today’s ad-hoc board level verification approaches with an ordered methodology that enables designers to automatically validate their own hardware designs, optimize system performance, and simplify the process of integrating new hardware with new software.
Memory is fundamental to the “sanity” of an embedded system. Inadequate memory testing is posing critical challenges to designers and indirectly manifesting considerable consequences at some of the biggest names in the electronics business. Today’s embedded systems consist of multiple memory types including SDRAM, LPDDR2, DDR3, FLASH, EEPROM and more, along with multiple protocols including GPIO, PCI, SPI and I2C. This paper will review a comprehensive and flexible Verification and Test Operating System (VTOS™) solution that includes a suite of memory tests that verifies the design for correctness and production readiness.
