ADIsimADC is Analog Devices' Analog-to-Digital Behavioral Model that accurately models the typical performance characteristics of many of our High Speed Converters (>10 MSPS). The model faithfully reproduces the errors associated with both static and dynamic features such as AC linearity, clock jitter, and many other product specific anomalies. More
There are three ways to use ADIsimADC. For simple product selection, a web-based application allows you to analyze ADC performance online. This tool requires no downloads and allows you to graph specific performance plots. ADC Analyzer™ is a downloaded tool that runs the behavioral models and configures evaluation boards. VisualAnalog™ takes this concept further by allowing designers to customize their input signal and data analysis. An input signal can be constructed from sine waves, noise sources, and vector data to see how an ADC will perform in real world conditions. Less
For simple product selection, a simple web based application is accessible from the product pages of devices that are supported by ADIsimADC. This tool requires no downloads and allows control of the test conditions and 'design' specific performance plots. Results are graphed which greatly reduces the uncertainty of how a part will perform in an application. The tool also allows input of desired operating conditions and required performance levels and it will recommend suitable devices to the user.
For designers who are selecting or evaluating high speed ADCs, VisualAnalog™ is a software package that combines a powerful set of simulation and data analysis tools with a user-friendly graphical interface. Many designers are familiar with ADCAnalyzer - a tool that models ADC performance with varying input frequencies and sample rates. VisualAnalog takes this concept further by allowing designers to customize their input signal and data analysis. An input signal can be constructed from sine waves, noise sources, and vector data to see how an ADC will perform in real world conditions. The data analysis functions are expanded from the basic FFTs that are available in ADCAnalyzer as well. Customizable calculations allow designers to predict adjacent channel power ratio (ACPR) and display I/Q constellation plots on simulated ADC outputs or data collected from evaluation boards. VisualAnalog™ is also used as a controller for a new data capture board (HSC-ADC-EVALCZ).

The high speed ADC SPI program allows the user to control advanced features on high speed, analog-to-digital converters (ADCs) with SPI capability. A complete list of features can be found in the specific product's data sheet and in the Application Note: High Speed ADC SPI Control Software (pdf).
Once a device has been selected, one of the tools listed below may be used to perform a system level simulation. Because the same model files areused throughout the process, from web application through 3rd party simulation, consistent results are achieved and the flow is seamless from part selection through final design verification. Other 3rd party tools are in development and will be available in the future.
ADISimADC is fully integrated with Agilent's SystemVue platform supporting ADC performance characterization with modern commercial wireless standards like 3GPP LTE, WiMAX, DVB-S2/T2 or advanced military software defined (SDR) radio systems. ADISimADC is also compatible with Agilent Technologies' Advanced Design System (ADS). Agilent's ADS enables Analog Devices ADCs to be interfaced directory to circuit level IF/RF for the industry's most accurate mixed signal modeling of high frequency systems.

ADIsimADC plug-in for National Instruments SignalExpress interactive measurement software. By using ADIsimADC with NI SignalExpress, you can apply custom inputs to the models and perform interactive signal chain analysis on a large selection of ADI's ADCs. You can also seamlessly transition between simulating and physically evaluating your component signal chain to verify real-world performance against simulation results. For more information about the ADIsimADC plug-in step for NI SignalExpress, contact National Instruments.
ADIsimADC may be used with Matlab on a PC platform. Instructions and the appropriate device driver files need to be downloaded.
