Designers can now point and click to implement analogue dividers, complex Bessel filters, and gain-polarity stages in a drift-free, integrated silicon platform

With the latest release of the AnadigmDesigner2 EDA software for field programmable analogue arrays (FPAAs), these circuit types join a growing list of analogue functions for which Anadigm is automating the design and implementation process. Widely used but difficult to implement with discretes, dividers and gain-polarity stages are being provided by Anadigm as configurable analogue modules (CAMs) that can be customised and then implemented within a FPAA device by a simple drag-and-drop process in AnadigmDesigner2 EDA software.

As part of the same release, the AnadigmFilter tool has now been enhanced to automate the design and implementation of both lowpass and highpass Bessel filters.

'At Anadigm we're committed to adding more functions on a regular basis to our CAM library as well as new features to our EDA tool suite', said Suhel Dhanani, Senior Product Marketing Manager at Anadigm.

'These latest additions allow more functions to be integrated within an FPAA and expand the range of applications in which FPAAs can be used'.

The new AnadigmDesigner2 capabilities were added in response to feedback from Anadigm FPAA customers, which include manufacturers of a wide range of industrial, automotive, medical, automatic test equipment, instrumentation, and communication products.

Each new CAM has a wide range of applications.

Designers who need to implement automatic gain control circuits or ratioing functions can use the divider CAM.

The automated Bessel filter can be used to implement complex filters with linear phase characteristics.

The gain-polarity stage is used in functions such as base comparators.

With the release of these new functions, Anadigm has abstracted more than 20 analogue functions into drag-and-droppable CAMs that reduce the design and implementation time for analogue circuits from months to a matter of minutes.

With the Bessel filter option, designers now have a choice of five approximations in AnadigmFilter, including Butterworth, Chebyshev, Inverse Chebyshev, and Elliptic.

AnadigmDesigner2 is the first EDA product on the market to allow designers to develop their designs using FPAAs that can be reconfigured by the microcontroller in real time to change the function they perform within a system or to adapt on the fly to maintain precision despite system degradation and aging.

Typical applications for FPAAs designed with AnadigmDesigner2 include signal conditioning, closed loop control, and data acquisition.

A trial copy of AnadigmDesigner2 is available for free download from the Anadigm website.

A complete evaluation kit with a development board, entry-level software and updated documentation is now available for $499.
