HSDIO PXIe-6556 Hardware compare for large files

I'm developing a system with Labview2013, TestStand2013, PXIe-6556 and HSDIO driver 2.0

The system diagram is:

Pxie-6556 >----------------------- 12 channels ------------------------------------ 4 channels ------> Dut1 (jtag 3ch out 1ch in)

Hardware compare mode                                         |-------------------- 4 channels ------> Dut2 (jtag 3ch out 1ch in)

                                                              |-------------------- 4 channels ------> Dut3 (jtag 3ch out 1ch in)

The goal is to develop a hardware compare mode test for a very large test vector file >10Gbytes

The issues are:

1. How to convert this file from csv or vcd to hws using the Digital waveform editor 3.0? (split in files of the xx Mbytes?)

2. How to implement the hardware compare mode. Load the file from disk in steps of xx Mbytes in a loop?

Thanks,
