Setting Up the SPI Controller Software
After the ADC data capture board setup is complete, set up the
SPI Controller software using the following procedure:
1. Start the SPI Controller software by selecting the SPI
SPI Controller software using the following procedure:
1. Start the SPI Controller software by selecting the SPI
controller software from the Start menu or by double-
clicking the SPIController software desktop icon. If
prompted for a configuration file, select the appropriate
one. If not, check the title bar of the window to determine
which configuration is loaded. If necessary, select Cfg
Open from the File menu and select the appropriate file
based on your part type. Note that the CHIP ID(1) field
should be filled to indicate whether the correct SPI
controller configuration file is loaded (see Figure 9).

3. In the ADCBase 0 tab of the SPIController window, find
the CLKDIV(B) box (see Figure 11). If using the clock
divider, use the drop-down box to select the correct clock
divide ratio, if necessary. See the

4. If the ADC sample rate is less than 100 MSPS, click the PLL
Input < 100 MSPS check box in the PLL CTRL(21) box of
the ADCBase0 tab. If you configured the FPGA for a clock
divider mode in Step 4 of the Setting Up the ADC Data
Capture section, select the appropriate clock divider setting in
the Divide ratio drop-down box located in the CLKDIV(B)
box. If you configured the FPGA for Output Configuration

5. Note that other settings can be changed on the ADCBase 0
tab (see Figure 11) and the ADC A and ADC B tabs (see
Figure 12) to set up the part in the desired mode. The
ADCBase 0 tab settings affect the entire part, whereas the
settings on the ADC A and ADC B tabs affect the selected
channel only. Note that for the
