Anadigm� Expands Drag-and-Drop Programmable Analog Building Block Options with New Configurable Analog Modules

Sep 27, 2004

TEMPE, Ariz. � Sept. 27, 2004 � Now designers can point and click to create square wave oscillators, a voltage-controlled sample and hold circuit, and a sum/difference stage with biquadratic filter. Originally developed by Anadigm� for customer-specific designs, these are among a new group of programmable analog building blocks now available for free download from

Each of the Configurable Analog Modules (CAMs) in this new �Customer Collection� can be downloaded to an Anadigm� Field Programmable Analog Array (FPAA) to implement a software-controlled function in an analog equivalent to the FPGA.

Compared with the standard CAMs provided with the AnadigmDesigner�2 EDA tool used for programming FPAAs, the new Customer Collection CAMs implement more complex, application-specific functions and are the result of customer requests for a drag-and-drop solution to specific design challenges.

The first Customer Collection CAMs being made available by Anadigm� include a sawtooth and square wave oscillator, a triangle and square wave oscillator, a sum/difference stage with biquadratic filter, a multiplier with low corner frequency LPF, and a voltage-controlled sample and hold.

Each of the new CAMs features one or more user-selectable parameters. For example, the sawtooth and square wave oscillator allows users to set the frequency, duty cycle, and peak level. The sum/difference stage with biquadratic filter allows users to choose from low pass, high pass, or band pass filter configurations. The voltage-controlled sample and hold provides users with the ability to select a comparison value for the control signal.

To implement the functions abstracted in the CAMs, users simply drag and drop the CAM into the graphic representation of the FPAA in AnadigmDesigner�2. Once the parameters are selected, the circuit is ready to be downloaded to the FPAA for testing and validation.

�We�ve always encouraged our customers to come to us with their requests for CAMs that meet specific needs while using circuit resources as efficiently as possible,� said Simon Dickinson, Vice President of Operations at Anadigm�. �The Customer Collection of CAMs available on our Web site includes examples of the solutions we�ve provided for particular customer applications that also have a potentially wide range of applicability to meet the needs of many customers in many vertical market segments.�

Anadigm is making available the Customer Collection of CAMs with the recommendation that performance expectations and appropriate applications be discussed with Anadigm� technical support before use. Designers are advised to bench-test circuits constructed with these CAMs to verify that the desired functionality is being achieved.

The Customer Collection of CAMs can be downloaded from a new Download Center within the Anadigm� Web site at, which also includes complete starter kits for several complex circuit types at and a Support Forum at that allows Anadigm� users to share experiences, design tips, and shortcuts for using FPAAs, AnadigmDesigner�2, and the AnadigmFilter� and AnadigmPID EDA tools.

A free trial copy of AnadigmDesigner�2 v2.4 is available for download at 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.
