I’m trying to capture traces using the magnetic field probe (h-probe) from an external FPGA (Altera DE-10 nano). I’m using CW lite (CW1173) as the capture board. The target FPGA has been powered up from the capture board, and the clock and trigger pins are also connected. I’ve programmed the target board with a custom design and I’m generating the appropriate trigger signal which has similar electrical properties compared to the trigger signal we can see when using XMEGA as the target board with AES implementation.
My problem is, I can’t get enough traces captured. Although I’m generating 4000 trigger signals, the capture board is capturing only about 300 (less than 10%).
I can’t figure out what makes the capture speed slower. What can be a potential problem for this kind of behavior? Any sort of help or suggestion will be highly appreciated.
