National Instruments Introduces Graphical Differencing and User Interface Toolkit for Comparing Models Developed Using The MathWorks, Inc. Simulink(R) Software.

Globally Valid Toolkit Simplifies Team-Based Development in Aerospace, Automotive and Medical Industries

AUSTIN, Texas -- National Instruments National Instruments, or NI (NASDAQ: NATI), is an American company with over 4,000 employees and direct operations in 41 countries founded in 1976 by Dr. James Truchard, Bill Nowlin and Jeff Kodosky.  (Nasdaq:NATI NATI National Association of Teen Institutes

) today announced the NI Graphical Differencing and User Interface Toolkit User Interface Toolkit (UIT) was a C++-language, object-oriented layer on top of the XView graphical toolkit. It was originally developed by the Sun Microsystems employees, Mark Soloway (left Sun in 1993) and Joe Warzecha (still an employee of Sun), as an internal tools , a software solution that helps engineers and scientists identify differences between models built using The MathWorks, Inc. Simulink([R]) software. Engineers and scientists also can use the toolkit to easily create user interfaces to interact with their models built using Simulink. The ability to easily compare models and identify differences makes the toolkit ideal for team-based application development in industries such as aerospace, automotive and medical. Valid for worldwide use, the toolkit is offered in collaboration with ExpertControl, a technical software company headquartered in Germany.

The toolkit makes it possible for users to compare and identify the structural, parameter (1) Any value passed to a program by the user or by another program in order to customize the program for a particular purpose. A parameter may be anything; for example, a file name, a coordinate, a range of values, a money amount or a code of some kind.  and visual differences between models including standard Simulink software blocks, subsystems, S-functions and statecharts developed using The MathWorks, Inc. Stateflow([R]) software. Users also can filter the list of differences to better view and manage the results. Additionally, users can visualize model differences in Simulink and export them to Microsoft Excel (tool) Microsoft Excel - A spreadsheet program from Microsoft, part of their Microsoft Office suite of productivity tools for Microsoft Windows and Macintosh. Excel is probably the most widely used spreadsheet in the world.

The Graphical Differencing and User Interface Toolkit includes the ecDIFF([TM]) graphical differencing tool for comparing models built using the Simulink software as well as the NI LabVIEW Base graphical programming environment and the LabVIEW Simulation Interface Toolkit, giving engineers and scientists a comprehensive, easy-to-use software environment for creating design, control and test applications and connecting models developed using the Simulink software to the real world. With LabVIEW and the LabVIEW Simulation Interface Toolkit, users can create custom user interfaces in LabVIEW to interact with their models developed using Simulink software. Engineers and scientists also can connect their models to real-time 1. real-time - Describes an application which requires a program to respond to stimuli within some small upper limit of response time (typically milli- or microseconds). Process control at a chemical plant is the classic example.  I/O (Input/Output) The transfer of data between the CPU and a peripheral device. Every transfer is an output from one device and an input to another. See PC input/output.

Containing up to hundreds of thousands of gates, there are a variety of FPGA architectures on the market.  modules.
