LTE impact affects semiconductor SoC, communications networking infrastructure, mobile devices, applications and quality services transforming means of communications to a new level – higher speed, multimedia content and [...]
Speeding FPGA Prototype Debug Process with Active Debug and Full Visibility
By Joe Gianelli and Tom Huang Introduction System integration continues to drive the semiconductor design market. This is most obvious when looking at the increased system integration associated with System on Chip (SoC) design over the last few years. Integrating complex hardware features with complex software applications onto one silicon device makes the validation process [...]
Selecting the Right Computer on Module Vendor
By Maheshwari Introduction Engineers have always been faced with the question of whether or not a Computer-on-Module (COM) company is the right vendor to partner with. To help with the decision, I have written an article to help engineers select the ideal COM partner. Target Usage First, it is important to identify the applications for [...]
35 Test Cases for User Interface Testing
When testing user interfaces, it is easy to overlook test cases that would be helpful for a more thoroughly tested solution. The following list identifies twenty test cases that should be considered when testing user interfaces.
20 Useful Test Cases for Testing User Interfaces
- Required Fields
If the screen requires data entry on a specific field, designers should identify the required fields with a red asterisk and generate a friendly warning if the data is left blank. - Data Type Errors
If the screen contains dates, numeric, currency or other specific data types, ensure that only valid data can be entered. - Field Widths
If the screen contains text boxes that allow data entry, ensure that the width of data entered does not exceed the width of the table field (e.g. a title that is limited to 100 characters in the database should not allow more than 100 characters to be entered from the user interface). - Onscreen Instructions
Any screen that is not self-explanatory to the casual user should contain onscreen instructions that aid the user. - Keep Onscreen Instructions Brief
While onscreen instructions are great, keep the wording informative, in layman’s terms, but concise.
Intel ATOM Processor Technology for Embedded Designs
Shrinking product development cycles coupled with demanding product requirements and increasingly complex design implementations can overwhelm a design team. The technical risk of employing new, complex, high-speed processor technology can often deter engineers from incorporating new technology in product designs. Intel Corporation’s ATOM processor and low power chipset solution is a technology choice which cannot [...]
Direct Digital Synthesis Components
Direct Digital Synthesis (DDS) is a method for generating arbitrary frequency sine waves with high accuracy and spectral purity. The ability to generate spectrally pure sine waves at programmable arbitrary frequencies is useful for instrumentation, communications products, and other applications. Today’s Direct Digital Synthesis components (DDS) provide highly accurate, spectrally pure sine wave generation with [...]
Automated Testing Framework for Automation Success
By Steve Miller This article discusses the key ingredients of an automated testing framework that can lead to test automation success. Why Automate Test Cases? Even though many companies run their regression test cases manually, it may make more sense to automate regression test cases. It makes sense to automate test cases when engineers can [...]
Custom Industrial Controller or Programmable Logic Controller?
By Paul Nickelsberg Designers use Programmable Logic Controllers (PLCs) extensively for industrial control applications. A PLC features a general processor architecture, a general input / output architecture, a general mechanical architecture, and a general software development architecture. Industrial designer engineers, factory automation engineers, and industrial controls developers can meet their needs with generalized solutions. However, [...]
The Secret to Choosing USB Devices for Industrial Applications
By Casper Yang Thanks to its ease of use and versatility, Universal Serial Bus (USB) is the most popular interface in the IT industry today. In recent years, USB has also gained popularity in industrial applications as more and more devices support the interface. However, industrial operations are more demanding than the typical office application [...]
Single Board Computers
Single Board Computers (SBCs) have developed rapidly due to miniaturization technology, which implements more functionality in smaller spaces. The technological progression of “integrated circuit” (IC) technology, which has created the SBC by reducing sizes for the central processing unit (CPU), program memory and disk controller units, so they can be stored on smaller “large scale [...]
