Featuring full support for the new entry-level AN221E02 FPAA, the new AnadigmDesigner�2 v2.4 also gives users the ability to add voltage-controlled variable gain stages, low-corner frequency bilinear low pass filters, sum/difference integrators, and square root functions to their analog circuit designs�simply by dragging and dropping Configurable Analog Modules (CAMs).
Enhanced simulation and check sheet coverage
AnadigmDesigner�2 v2.4 features extensive improvements to support post-simulation probing of circuits designed in FPAAs, including an enhanced oscilloscope feature that provides a real-time trace display during simulations. All data at all output nodes is now saved after a simulation run, allowing designers to test the simulated circuit with virtual oscilloscope probes. The oscilloscope subsystem further allows users to save probed data to a CSV file. After simulation, probes may be moved about and additional CSV files can be generated as needed.
Complex analog circuits created using AnadigmDesigner�2 are based on pre-qualified software modules, ensuring that designs are correct by construction, repeatable, and automatically translated into C-code. With AnadigmDesigner�2 2.4, the correct-by-construction feature is enhanced with additional check sheet coverage, through which visual cues are provided immediately to the user if the software detects a phase mismatch, misconnected wire, or other irregularity. The check sheet function automatically checks for a wide variety of potential circuit design problems and allows the user to correct or ignore them.
New Configurable Analog Modules (CAMs)
Four new CAMs are included with AnadigmDesigner�2 v2.4. A voltage-controlled variable gain stage CAM creates circuitry that alters the gain of a signal path as controlled by an external signal or through closed-loop feedback. A new low corner frequency bilinear low-pass filter CAM allows designers to implement a filter with a corner frequency that is decades lower than that of the standard bilinear filter CAM, extending the capabilities of the FPAA with the use of external capacitors. A sum/difference integrator CAM acts as an integrator on the sum or difference of up to three input voltages, which can be used to create closed loop feedback circuits, while a new square root CAM generates the square root of the input voltage and can be used for linearization or RMS calculation.
In addition to these new CAMs, AnadigmDesigner�2 v2.4 includes upgraded versions of the bilinear filter and biquadratic filter CAMs, enabling the creation of non-inverting low-pass filters.
A multimedia demonstration of AnadigmDesigner�2 v2.4 can be viewed at the Anadigm� Web site at http://www.anadigm.com. A free trial copy of AnadigmDesigner�2 v2.4 is available for download at http://www.anadigm.com/Down_05_a.asp. A complete evaluation kit with a development board, entry-level software, and updated documentation is now available at a promotional price of $199. Pricing for FPAA silicon starts at $4.95 in 1,000-piece quantities.

About Anadigm�
Anadigm� brings platform-based design to the analog world with pre-qualified software and hardware components that allow complex analog circuits to be implemented in an analog equivalent to the FPGA. Designed to implement signal conditioning, filtering, data acquisition, closed-loop control, and other analog functions in a wide range of embedded systems, Anadigm� FPAAs are first programmable analog ICs that can adapt on the fly to perform multiple functions, adjust to different environmental conditions, or compensate for equipment aging. Founded in January 2000 as a venture-backed technology spin-off from Motorola, Anadigm� maintains U.S. headquarters in Campbell, Calif., and European headquarters in Crewe, U.K. For further information, visit Anadigm� on the Web at http://www.anadigm.com.
