I'm glad that my last minute thought turned out to be the problem. It is
too bad that the simulator cannot pick this info up from the assembler,
but it does not.  The assembler summary of bytes used, bytes remaining
and percentage used should also reflect whatever device you specified in
the project file (in terms of correct sizes).

When first starting a project (using I guess what is called the wizard),
it steps you through the project name, whether it is ASM or C, etc. but
most importantly it allows you to specify the debug method (simulator)
AND the AVR device (tiny25 in your case).  If you specify device when
starting a project, you don't need to be concerned about it later when
you start simulation -- unless you change chips in the middle of the stream!

You are apparently also becoming familiar with the Intel hex files that
the assembler/compiler puts out (and the .eep file).  You can Google and
read up on the format, but essentially there are not line numbers, but
number of data bytes, starting address, record type, data bytes, and a
checksum at the very end of line.

You're on you way...
