Models would not build after unhooking library from master model
From Bugzilla 1065

This happened for l1isibs.mdl model which we tried to unhook from isi2stagemaster.mdl

Needs to be solved to allow completion of an upcoming ECR for seismic

So I looked at the l1isibs_partConnectionList.txt file in the original case (linked to the master file) against the case where it failed to compile (when we broke the link to the master file).
I found in the 39,000 line file at least one failure (there may be more).
In the good case, the the BS ST1 Demux8 is processed correctly:
OUT TO: ... BS_ST1_T240SUBTRACT_Sum SUM 2844 0 2 ...
However in the broken link case, it has:
OUT TO: ... BS_ST1_Goto44 0 2 ...
Somehow, the "demuxer part -> bus part -> bus selector part -> goto tag -> from tag" is getting confused in the BS->ST1 block. It is unclear if its some kind of naming problem conflict the top level (although we did try rebuilding the model with all the from/gotos and the non-ADC bus selectors names changed, which did not help).
This was rev 13086 of the /opt/rtcds/userapps/trunk/isi/l1/models/l1isibs.mdl and 13585 of the /opt/rtcds/userapps/trunk/isi/common/models/isi2stagemaster.mdl, and trying to disable and break the link for the "BS" block in the l1isibs model.

Been working this for a couple of days. It appears that the signal Goto tag RZ_T240 is not being removed properly i.e. signal not passing into subsystem T240SUBTRACT. I added diagnostics to the RCG tag removal process, but don't see any difference from the linked model, other than the order in which tags are being removed. If I remove this Goto tag and replace with a line, then the model compiles correctly.
Will continue to investigate. Since this tag goes to a BusSelector, it could be a problem with the bus removal portion of the RCG.
