QUICK START GUIDE: VIRTUAL EVALUATION USING ADIsimADC
REQUIREMENTS
•
Complete installation of ADC Analyzer, Version 4.8.2 or later.
•
Download ADIsimADC product model files for the desired
converter. (Models are not installed with the software, but
they can be downloaded from the
ADIsimADC Virtual
Evaluation Board
website at no charge.)
Note that no hardware is required to virtually evaluate an ADC
using ADIsimADC. However, if you wish to compare these results
to those using a real evaluation board, you can easily switch
between the two, as outlined in the following Quick Start Steps
section.
QUICK START STEPS
1.
Visit
www.analog.com/ADIsimADC
and download the ADC
model files of interest to a local drive. The default location
is c:\program files\adc_analyzer\models.
2.
Start ADC Analyzer (see the
ADC Analyzer User Manual
at
www.analog.com/FIFO
).
3.
From the menu, click
Config
>
Buffer
>
Model
as the
buffer memory. In effect, the model functions in place of
the ADC and data capture hardware.
4.
After selecting the model, click
Model
(located next to the
Stop
button) to select and configure which converter is to
be modeled. A dialog box appears in the workspace, where
you can select and configure the behavior of the model.
5.
In the
ADC Modeling
dialog box, click the
Device
tab and
then click
… (Browse)
, which is the button adjacent to the
open box in the dialog window. 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
repeat Step 1 to install the 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, click
Config
>
FFT
. In the FFT
Configuration dialog box, ensure that the
Encode
Frequency
is set to 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 of the
ADC Modeling
dialog box. After ensuring that you have selected the
correct model, click the
Input
tab. This lets you configure
the input to the model. Click either
Sine Wave
or
Two
Tone
for the input signal.
8.
Click
Time Data
(the leftmost button under the pull-down
menus). A reconstruction of the analog input is displayed
.
The model can now be used 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. Consult the
ADC Analyzer User
Manual
at
www.analog.com/FIFO
for more information.
