Debugger Files

Debugger files provide input to the debugger to define support for simula-
tion or emulation of your program. The debugger supports all the
executable file types produced by the linker (
To simulate I/O, the debugger also supports the assembler's data file
format ( ) and the loader's loadable file formats (.
.DAT
The standard hexadecimal format for a SPORT data file is one integer
value per line. Hexadecimal numbers do not require a
can have any number of digits, but is read into the SPORT register as:
• The hexadecimal number which is converted to binary
• The number of binary bits read which matches the word size set for
the SPORT register, which starts reading from the LSB. The
SPORT register then fills with zero values shorter than the word
size or conversely truncates bits beyond the word size on the MSB
end.
Example
In this example, a SPORT register is set for 20-bit words and the data file
contains hexadecimal numbers. The simulator converts the hex numbers
to binary and then fills or truncates to match the SPORT word size. In
