The included PIN tool champsim_tracer.cpp can be used to generate new traces. It has been tested (April 2022) using PIN 3.22.

Download and install PIN

Download the source of PIN from Intel's website, then build it in a location of your choice.

wget https://software.intel.com/sites/landingpage/pintool/downloads/pin-3.22-98547-g7a303a835-gcc-linux.tar.gz
tar zxf pin-3.22-98547-g7a303a835-gcc-linux.tar.gz
cd pin-3.22-98547-g7a303a835-gcc-linux/source/tools
make
export PIN_ROOT=/your/path/to/pin

Building the tracer

The provided makefile will generate obj-intel64/champsim_tracer.so.

make
$PIN_ROOT/pin -t obj-intel64/champsim_tracer.so -- <your program here>

The tracer has three options you can set:

-o
Specify the output file for your trace.
The default is default_trace.champsim
 
-s <number>
Specify the number of instructions to skip in the program before tracing begins.
The default value is 0.
 
-t <number>
The number of instructions to trace, after -s instructions have been skipped.
The default value is 1,000,000.

For example, you could trace 200,000 instructions of the program ls, after skipping the first 100,000 instructions, with this command:

pin -t obj/champsim_tracer.so -o traces/ls_trace.champsim -s 100000 -t 200000 -- ls

Traces created with the champsim_tracer.so are approximately 64 bytes per instruction, but they generally compress down to less than a byte per instruction using xz compression.
