The simulator supports several options including the trace option (-t) and the statistics option (-s). Use the option --help for more information.
The first set of options are given to the run command along with the name of the execurtable file.
Options: -a "ARGS", --args "ARGS" Pass ARGS to simulator -B, --branch-report Print branch coverage report -b, --branch-summary Print branch coverage summary -C, --coverage-report Print coverage report -c, --coverage-summary Print coverage summary -d T, --delay T Delay trace for T uSec -f MOD, --file FILE Report coverage for this source file only -h, --help Print this message -i I, --pending I Trigger trace on pending interrupt I -I I, --interrupt I Trigger trace on interrupt level I -l T, --limit T Time limit T uSec -m, --trace-memory Trace data memory cycles -M, --trace-memory-wide Trace data and instruction memory cycles -p, --perf Print performance summary -P PC, --pc PC Trigger trace on pc = PC (use 0x for hex) -r, --ram-tags-report Print RAM tags report with large blocks -R, --RAM-tags-report Print RAM tags report with small blocks -s, --stats Print execution statistics -t, --trace Trace instructions using 70 columns -T, --trace-wide Trace instructions using wide format -u U, --resolution U Set task trace resolution to U uSec -v, --verbose Print additional information -V, --version Print version number -w, --wide Widen a trace or report -y, --nosys Don't pass system calls to host -z, --tasking-report Print task switching report -Z, --tasking-report-wide Print task switching report wide format
This second set of options are passed to the simulator within the run command, and to do this you need to use the run command's option -a as follows:
Simulator options are:
-edac Also simulate the EDAC
-trace-edac Trace any unusual EDAC operations
-mer D Set memory error rate to F SEUs per day
-fill Fill memory with test pattern
-eram-size S Simulate S K Bytes of extended RAM
-mcnfr MCNFR Initial value for MCNFR (default 0x00010000)
-freq F Set the clock frequency to F MHz (default 20 MHz)
-fpu Run with floating point unit (default)
-no-fpu Run without floating point unit
-no-gdb Make trap 1 available to applications
-no-tn0 Don't stop on 'tn 0'
-sof Stop on fault (default)
-no-sof Don't stop on fault, call handler
-sorbw Stop on read-before-write
-no-sorbw Don't stop on read-before-write, (default)
-uarta DEV Connect UARTA to DEV (default stdin/stdout)
-uartb DEV Connect UARTB to DEV
-uben Swap roles of UARTs A and B
-ift Set the input IFT
-no-ift Clear the input IFT (default)
-prom8 Set the input PROM8 (8-bit PROM) (default)
-no-prom8 Clear the input PROM8 (40-bit PROM with EDAC)
-romwrt Set the input ROMWRT (enable PROM write)
-no-romwrt Clear the input ROMWRT (no PROM write) (default)
Trace format is:
142.000 nzvc 15 spe 7 02000F34 sethi %hi(0x2100000), %g1
| | | ||| | | |
| | | ||| | | - Disassembled instruction

| | | ||- Enable Traps (ET)
| | | |- Previous Supervisor (PS)
| | | - Supervisor mode (S)
| | - Processor Interrupt Level (PIL)
| - IU Condition codes (ICC)
- CPU time in microseconds
Report problems to <support@xgc.com>The trace option prints each instruction as it is executed, along with the execution time in microseconds, and the instruction address. If the debug option was used when the source files were compiled, then source code line numbers will be printed too.
