The Virtual Prototype; An Advanced Reality Check in the Iterative Simulation Process?
A powerful process to drive efficiency in the design flow is iterative simulation. Simulation applies a mathematical model to a design allowing analysis without having to physically build a prototype. Circuit designers are able to utilize simulation in the form of SPICE and XSPICE to predict the behavior of a circuit and analyze the effects of various components and signals in the design

Designers and engineers are now able to improve the iterative simulation process by utilizing a virtual prototype in their design. The virtual prototype is a distinct step in the iterative simulation process which acquires a real-signal and introduces this data into a SPICE simulated circuit). By combining a mathematical model of a circuit with real stimuli, an engineer can better approximate the behavior of a circuit and therefore improve the final product of the design stage.

Company and Product News
Connect and Control Benchtop Instrumentation via your PC
National Instruments is a leading provider of high-quality General Purpose Interface Bus (GPIB) controller hardware for instrument control. GPIB delivers a reliable and easily configurable interface to connect measurement instruments to the personal computer to acquire and save real data. NI GPIB products offer three key benefits to help save you time and money throughout the life of your instrument control system - from development through production and maintenance. You can rely on hardware and software that offers improved performance, high reliability, and increased productivity.

National Instruments software such as the powerful NI LabVIEW graphical programming language, provide out-of-the box instrument connectivity to integrate bench-top instruments into the design and test process through GPIB.

Both hardware and software have been specially designed so measurements can be taken quickly with little set-up time. With NI-GPIB, circuit designers can easily acquire data from bench-top function generators, and integrate this test data into circuit simulation. This process, called virtual prototyping, allows any engineer to use real data during simulation that contains the noise, phase-shift and other elements that cannot be introduced through SPICE simulation alone.

PCB West 2007
National Instruments Electronics Workbench Group were pleased to join the many exhibitors at the Santa Clara Convention center for the 27th and 28th of March for the 16th annual PCB West Design Conference. The event was a great success as National Instruments showcased the integration between NI Multisim schematic capture and NI LabVIEW test and measurement. This different take on the PCB design flow to enable efficiency through the power of virtual test, continued to resonate through the professional community, as engineers descended upon Silicon Valley for the two day exhibition.

Conference Highlights:
  •  In an exciting live demonstration, NI LabVIEW was used to acquire a real ECG signal which was immediately utilized as a simulation source in NI Multisim. This unconventional demonstration showcased the power of the integration of virtual test with circuit simulation to effectively bring real-world sources and stimuli into the world of SPICE simulation.
  • Congratulations to Robert Badal of San Jose who was the lucky winner of the LEGO Mindstorms NXT robot kit. Powered by NI LabVIEW, future and present engineers alike can easily and intuitively program a LEGO ® robot! We hope you have fun Robert!

Passive Component Placement Improved in NI Multisim 10.0
NI Multisim 10.0 introduces a new intuitive interface for selecting and customizing passive components. Previously, designers needed to use virtual components in order to specify arbitrary values for passive components. Virtual components could not be transferred to PCB layout since they did not specify a footprint.

NI-EWB R&D Staff Tip of the Month
To make source code development for microcontrollers easier, the NI Multisim MCU Module includes an interactive debugging environment that facilitates the debugging process. Using the debugging tools you can follow and track the sequence of events in a program using breakpoints, debug stepping and a view of the memory and registers populated during simulation. With these features you can interactively check the C and assembly code created for the microcontroller.
