Simulator Traces[edit]

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

• Packed Differential Address and Time Stamp (PDATS) Trace
• Program Counter Discontinuity Trace (PCD) Trace
• Execute Packet (EP) Trace

Generate Traces using Scripting/Loadti[edit]

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[edit]

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[edit]

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[edit]

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.
