Issue Details

I have a system which is setting as below.
 

  1. DUT with 60pins.
  2. 6571*2set(each have 32 DIO pins).
  3. Enable 1 site only.
  4. Without PXIe-6674T in my system.

I would like to know whether there will be timing issue or other issues on this setting in my system.

Solution

If you are not using the match and fail opcode, 6674T is never needed for multiple 6570/1s in one chassis to burst pattern simultaneously.

"Match" & "Fail" opcode is using for flow control.
You can refer more by below spec link.

Additional Information

With the use of multi-657x instrument sessions, which is first supported on 19.0. Open the session by passing the resource names as a comma separated list and then have the pin map and pattern updated accordingly.
