I was helping out another customer and thought the result might be useful to others.

I wrote an SBA script which can trace a block signal to all of the blocks that connect to it, including tracing through a superblock reference. That way, you can see the direct uses of a particular signal.

The script contains some docs, it's simple to use, but the output is cryptic, but all of the trace information you'd want is presented. (It's gets tough when a signal traces through a superblock)

Here's a sample:  (tracesignal(98,1)) (using the discrete cruise system example model from cruise_d.cat)

Discrete Cruise System::continuous automobile.98 (1){auto speed}->
     Ext.Out (3) 
Discrete Cruise System::continuous automobile.98 (1){auto speed}->Cruise Control System.33::(5){auto speed}->
Discrete Cruise System::continuous automobile.98 (1){auto speed}->Cruise Control System.33::(5){auto speed}->Set Speed.13::(2){auto speed}->
     External Input Buffer.46(1)
Discrete Cruise System::continuous automobile.98 (1){auto speed}->Cruise Control System.33::(5){auto speed}->Controller Logic.57::(2){auto speed}->
    speed error.32(1)

ans (a scalar) = 3

Hope you can use it!
