How to connect ILA trigout to 2 ILA trigin

Hi,

  I am familiar with using TCL commands to connect TRIGOUT to TRIGIN between 2 ILAs.

  I would like to know connect 1 ILA TRIGOUT to 2 ILA TRIGIN.  Specifically, I do not know how to connect TRIG_IN_ACK outputs from the 2 downstream ILAs.  

 

Regards,

Neo

Re: How to connect ILA trigout to 2 ILA trigin

The best way to do this is through HDL. This flow is explained in UG908 on page 137/138. You would take the trigout of ILA 1, and pipe it to both of the other ILAs trigin ports. Then take their trig_in_ack and and/or them together depending on the trigger situation. You might need to play with the timing a bit, but there is a timing diagram for reference on page 139.
