Software eases application of analogue
arrays
New features in Anadigm's programmable analogue design software add a higher level of realism to simulations of field programmable analogue arrays.
New features in Anadigm's programmable analogue design software add a higher level of realism to simulations of field programmable analogue arrays (FPAAs) while providing further safeguards to ensure that designs made in AnadigmDesigner2 will seamlessly translate into working analogue circuits Featuring full support for the new entry-level AN221E02 FPAA, the new AnadigmDesigner2 v2.4 also gives users the ability to add voltage-controlled variable gain stages, low-corner frequency bilinear lowpass filters, sum/difference integrators and square root functions to their analogue circuit designs - simply by dragging and dropping configurable analogue modules (CAMs)

Software puts standard filters on analogue arrays
Anadigm has added filter synthesis to its field-programmable analogue array (FPAA) configuration software.
AnadigmDesignerR2 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 are 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 analogue circuits created using AnadigmDesigner2 are based on prequalified software modules, ensuring that designs are correct by construction, repeatable, and automatically translated into C code.
With AnadigmDesigner2 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.
Four new CAMs are included with AnadigmDesigner2 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 lowpass 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 linearisation or RMS calculation.
In addition to these new CAMs, AnadigmDesigner2 v2.4 includes upgraded versions of the bilinear filter and biquadratic filter CAMs, enabling the creation of noninverting lowpass filters.
A multimedia demonstration of AnadigmDesigner2 v2.4 can be viewed on the Anadigm website, where a free trial copy is also available for download.
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 1000-piece quantities.
