VIRTUAL EVALUATION BOARD QUICK START WITH ADIsimADC
REQUIREMENTS
Requirements include
•
Completed installation of ADC Analyzer version 4.5.0 or
later.
•
ADIsimADC product model files for the desired converter.
Models are not installed with the software, but may be
downloaded from the website at no charge. Go to
www.analog.com/ADIsimADC
Tools for the product of interest.
•
No hardware is required. However, if you wish to compare
results of a real evaluation board and the model, you may
switch easily between the two, as outlined below.
Quick Start Steps
1.
To obtain ADC model files, go to
www.analog.com/ADIsimADC
Tools for the product of interest. Download the files of
interest to a local drive. The default location is c:\program
files\adc_analyzer\models.
2.
Start ADC Analyzer (see the Installation section for
installing the software).
3.
From the menu choose Config > Buffer and select Model
from the drop down menu as the buffer memory. In effect,
the model functions in place of the ADC and data capture
hardware.
4.
After selecting the Model, a small button, Model, is
displayed next to the Stop button. Click Model to select
and configure which converter will be modeled. This places
a small form in the workspace where you can select and
configure how the model will behave.

5.
On the ADC Modeling form, select the Device tab and
...
click the
button, adjacent to the dialog box. This opens a
file browser and displays all of the models found in the
default directory: c:\program files\adc_analyzer\models. If
no model files are found, follow the on-screen directions or
see Step 1 to install available models. If you have saved the
models somewhere other than the default location, use the
browser to navigate to that location and select the file of
interest.
6.
From the menu choose Config > FFT. In the FFT
Configuration form, ensure that the Encode Frequency is
set for a valid rate for the simulated device under test. If set
too low or too high, the model will not run.
7.
Once a model has been selected, information about the
model displays on the Device tab. After ensuring that you
have selected the right model, select the Input tab. This lets
you configure the input to the model. From the drop down
menu, select either Sine Wave or Two Tone for the input
signal.
8.
Click Time Domain (left-most button under the pull-
down menus). A reconstruction of the analog input is
displayed. The model may now be used just as a standard
evaluation board would be.
9.
The model supports additional features not found when
testing a standard evaluation board. When using the
modeling capabilities, it is possible to sweep either the
analog amplitude or the analog frequency. See the
Installing ADC Analyzer With ADISIMADC section for
additional features.
