The simulator is going to compute all of the signals at all of the nodes.

But you could make a copy of the test script and remove the nodes you don't care about from the output list. But you would need a valid compare file for it. If it's not too long, you could remove the corresponding entries by hand. Otherwise you could bring it into a spreadsheet, delete the columns, and write it back out to a text file.

There's also a syntax for the test scripts that tell it to ignore values (useful when you want to see some information but don't know what the result will be ahead of time or when it might vary from program to program). I don't know that that would be any easier to use.
