Hi, I have a problem with testjet wiring. We have developed a dual well fixture, with 3 modules testhead. UUT has IC on top and bottom layers. Originally TJ for IC on top layer were supposed to be wired to 3 mux cards on top. But this is a dualwel fixture, builder tried to wire the tj on top layer to the free ports on mux cards on bottom to get rid of top mux cards. Now my TJ test for IC on top layer is not working.
How do I fix this ? Can I change files, wirelist , testjet_mux... to make the new wiring work ?
Please help.
How do avoid this sittuation (3 mux cards on top of dualwell fixture) happens again while developing ?
Thank you

wirelist changes example: (Original is mux 1 port 1 -> moved to New mux 2 port 17)
device "1%u14"; top mux 1 port 1
..
..
end device
----------------------------------------------------------
device "1%u14"; mux 2 port 17
..
..
end device
You need to take care the timing module of the test. (Must match accordingly) Example:
test testjet "1%testjet"
timing module 2 -> 3
In future, at IPG Test consultant using Interactive Development mode ater "Generate Tests Using IPG" step.
Open and edit testjet file, add in "bottom" keyword to all the tests. In the example below: device "j5" need to add "bottom"
Once completed, save the file. Continue the rest of the steps until recalculate Dependencies.
device "j4" bottom
..
end device
device "j5"
