Trying to write a test for CheckZero16 chip

I've got a CheckZero16 chip of my own devising working (I think), and I thought I had correctly formatted a tst file to run tests on it:

Here's the Chip:

and here's the cmp file:

and here's the current output:

https://gist.github.com/tansaku/d77b8c83a17f378f97a3

However when I run in the hardware simulator I get "comparison failure at line 1".  Am I missing something obvious - or is there something such as a character limit on the outputs, e.g. have to be max three chars?

Is the tst file format documented anywhere?

Many thanks in advance
