Chapter 11: Emulator/Analyzer Interface Commands
display trace
depth
<DEPTH#>
This defines the number of states to be uploaded by the interface.
Note that after you have changed the trace depth, execute the command wait
measurement_complete before displaying the trace. Otherwise the new trace states
will not be available.
dequeue
This obtains a trace list showing the activity of the emulation processor during the
trace. Unused prefetches are eliminated from this display, and data transactions are
aligned with the instructions that caused them to occur.
disassemble Displays the trace at a certain line number and disassembles instruction opcodes.
_from_line
_number
--EXPR-- An expression is a combination of numeric values, symbols, operators, and
parentheses, specifying an offset value to be subtracted from the addresses traced
by the emulation analyzer. See the EXPR syntax diagram.
high_word Causes inverse assembly to begin with the opcode in the high word of the long
word located in the specified trace-memory line number. This field is isn't
applicable for the 68340 because its data bus is 16-bits wide.
instructions_only
Causes the trace list to contain only those lines that show an instruction opcode.
<LINE#>
This prompts you for the trace list line number to be centered in the display. Also,
you can use <LINE#> with disassemble_from_line_number. <LINE#> prompts
you for the line number from which the inverse assembler attempts to disassemble
data in the trace list. When used with align_data_from_line, this is the line
number from which to begin aligning data. The line number specified for data
alignment must be the same as, or higher than, the line number specified for the
beginning of the trace disassembly.
low_word Causes inverse assembly to begin with the opcode stored in the low word of the
long word at the specified trace memory line number. This field is isn't applicable
for the 68340 because its data bus is 16-bits wide.
mnemonic Lists trace information with opcodes in mnemonic format.
offset_by This option allows you to offset the listed address value from the address of the
instruction. By subtracting the offset value from the physical address of the
instruction, the system makes the listed address match that given in the assembler
or compiler listing.
