Platforms speed FPGA development
Nu Horizons Electronics Corp has two new development platforms based on the Spartan-3 family of low cost FPGAs from Xilinx.
Nu Horizons' signal processing virtual lab is the first of its kind to incorporate the Mathworks Simulink simulation and model-based design with both analogue-to-digital (A/D) convertor interfaces and digital-to-analogue (D/A) convertor modules.
In addition, the lab offers test equipment to provide signal insertion and measure output waveforms.
The signal processing virtual lab is configured to allow users to create and download high performance DSP applications.

Global distribution for analogue arrays
Anadigm's full line of field programmable analogue arrays is now available via Nu Horizons Electronics Corp throughout North and South America, Europe and the Asia Pacific region.
Advanced algorithms can be developed and complex measurements performed via a full complement of test equipment connected to the virtual lab environment.
Both a signal/pattern generator and high speed oscilloscope connect to A/D and D/A modules and each piece of test equipment is placed in the host mode in order to remotely manage the equipment's front panel controls.
Settings and scripts are also easily saved for re-use on future sessions, while the signal insertion output measurement capability within the lab enables designers to validate their algorithms.
"Nu Horizons is committed to offering quick and easy access to new technologies", explains Athar Zafar, Vice President of Global Engineering for Nu Horizons.
"This lab enables customers to evaluate Xilinx FPGAs for signal processing applications in an online environment, providing users with accurate measurements, authentic results and greater confidence in their findings".
Reference DSP designs are provided in the virtual lab environment, allowing the design engineer to evaluate the Spartan-3 2000 FPGA in a preverified environment with ease.
The Nu Horizons signal processing virtual lab consists of three reference labs.
Lab 1, the SysGen Tutorial, introduces customers to other important design features including: ChipScope, HDL Cosim, Hardware Cosim and PicoBlaze.
Lab 2 includes FFT with 256 tap FIR filter and interpolation by 3 - a lab offering ease of use and reasonably high performance allowing design engineers to evaluate tool interfaces as well as hardware.
The filter design is provided to the design engineer using the FDA Tool to generate coefficients, offering the designer the ability to modify coefficients and view results.
Simulation can be run in Sysgen, as well as run live in hardware.
Lab 3, an equalised 16-QAM demodulator including the adaptive filter, provides subsystems demonstrating adaptive channel equalisation and carrier tracking on a random QAM data source.
