Simulator Traces

Simulator provides the following traces to capture and analyze CPU activity.

Generate Traces using Scripting/Loadti

In CCSv4, simulator traces can be generated using DSS scripting or Loadti. Loadti is the generic script built on top of DSS scripting.

Loadti Simulator Enhancement

Loadti is available along with CCSv4 at "<CCSv4 install directory>\CCSv4\DebugServer\scripting\examples\loadti".

Loadti simulator enhancement to generate traces - Loadti.zip
Unzip the loadti.zip file at "<CCSv4 install directory>\CCSv4\DebugServer\scripting\examples\loadti" to get the enhancements.

Loadti Command Options

Loadti support the following set of options. To get this options use "--help" option in command line.

Usage: loadti [OPTION]... [OUT_FILE] [ARGUMENT]...
Load OUT_FILE executable to TI target and run, passing ARGUMENT(s) to main.

Mandatory arguments to long options are mandatory for short options too.
Options:
  -a,   --async-run
  -c,   --ccfg-file=CCS_CONFIG_FILE
  -o,   --o=out_file
  -h,   --help
  -l,   --load
  -mlr, --mem-load-raw="PAGE,ADDR,FILE,TYPE_SIZE,BYTE_SWAP"
  -mld, --mem-load-dat="PAGE,ADDR,FILE,LEN"
  -msr, --mem-save-raw="PAGE,ADDR,FILE,LEN,TYPE_SIZE,BYTE_SWAP"
  -msd, --mem-save-dat="PAGE,ADDR,FILE,LEN,IO_FORMAT,APPEND"
  -n,   --no-profile
  -q,   --quiet
  -r,   --reset
  -s,   --stdout-file=FILE
  -t,   --timeout=VALUE
  -v,   --verbose
  -x,   --xml-log=FILE
  -trace=<trace1>:<trace2> - Enable Simulator traces. Trace options on Simulator - PCDT, PDATS & EPT
  -start_trace=<label_1>:<label_2>:<PC address> - Enable trace from start label or PC address. Can specify multiple labels/PC Address
  -end_trace=<label_1>:<label_2>:<PC address>  - Disable trace at end label or PC address. Can specify multiple labels/PC Address

Loadti Usage

Loadti enables you to collect simulato traces for entire run or for selected function or between to any to PCs.

Simple usage to generate trace for the full simulation.

loadti -c=tisim_tci6484_ca.ccxml –o=test1.out –trace=PCDT:PDATS:EPT

Trace generation between two labels.

loadti –c=tisim_tci6484_ca.ccxml –trace=PCDT:PDATS –start_trace=startTrace –end_trace=endTrace –o=test1.out

Trace generation between labels & PC address

loadti –c=tisim_tci6484_ca.ccxml –trace=PCDT:PDATS –start_trace=startTrace1:startTrace2:0xe0001456 –end_trace=endTrace1:endTrace2:0xe0001576 –o=test1.out

Note: PC address should be suffixed with ‘0x’
Note: PDATS/PCDT need to be enabled seperately in the configuration file. Refer the PDATS & PCDT on how to enable them in simulator configuration file.
