TROUBLESHOOTING TIPS

EVALUATION BOARD FUNCTIONING

If the evaluation board is not functioning properly, take the
following steps:
1. Ensure that the evaluation board is properly seated in the
FMC connector.
2. After ACE has programmed the FPGA, power is provided
to the evaluation board for the AD908x-FMCA-EBZ
board. For the AD998x-FMCA-EBZ version of the boards,
power is provided externally through the 12 V connector.
Ensure that the LEDs that denote power are all lit. See
Figure 32.

3. Ensure that the eRPC server has made a successful connection
to the evaluation board. If the chip information reads back
a successful user identification (UID), this means that the
connection is successful. Otherwise, the UID reads 0x0
(see Figure 13). If this is the case, power cycle the
evaluation board and restart all software.

ACE SPEED ISSUES

If ACE is slow to capture data and setup the evaluation board,
take the following steps:
1. Ensure that the USB connection between the
V2EBZ board and the PC is done through a USB 3.0 cable.
2. Connect the cable to a USB 3.0 supported port on the PC.
3. Restart all software and hardware.

DATA CAPTURED ISSUES AFTER SETUP

In some instances, users may be unable to capture data from the
FPGA, which is characterized by no capture within the ACE
software or as a configure channel failed error in the ACE
software. In either case, only four of the six LEDs on the FPGA
board are lit (see Figure 33).

If this happens, and the setup is using an external direct clock to
the chip, ensure that the instrumentation is setup as shown in
Figure 30. Ensure the correct clock and reference clock
frequencies are set. Check the connections to the evaluation
board to ensure that the connections are snug. If the problem
persists, open the DPGDownloaderLite software (included with
the ACE installation) and download a tone (see Figure 28).
After this step, a successful data capture shows all the LEDs lit
(see Figure 34).
