TQSIM (Timed QEMU-based Simulator)

We present TQSIM, an open source, fast, and cycle-approximate simulation tool built on QEMU to support simulation of generic modern superscalar out-of-order processors. TQSIM is developed by Codesign and Parallel Processing Laboratory(CAPLab), Seoul National University, and sponsored by Samsung Advanced Institute of Technology (SAIT).

You can find more details about TQSIM in future literatures from CAPLab. (will be available at http://iris.snu.ac.kr/xe/papers)

Licence

TQSIM is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation, version 3.

Installation

To install TQSim on a linux system, do the following steps:

  1. Satisfy external dependencies: build-essential, gcc, pkg-config, glib-2.0, libglib2.0-dev, libsdl1.2-dev, zlib1g-dev, libxml2-dev, libpthread-stubs0-dev. In case you can use Advanced Packaging Tool (APT), do the following:
sudo apt-get install build-essential gcc pkg-config glib-2.0 libglib2.0-dev libsdl1.2-dev zlib1g-dev libxml2-dev libpthread-stubs0-dev
  1. Change the current directory to the main directory of the source tree (We will just call it TQSIM_SRC for short), then move in (TQSIM_SRC)/src.
  2. Modify tqsim_configure to be suitable for your environment. In case you want to install the package in another place than the specified user directory ($HOME/tqsim), change it to the desired place (TQSIM_BIN for short).
  3. Configure the package:
./tqsim_configure
  1. Compile the package:
make
  1. Install the package:
make install

In order to execute TQSim, it is required to provide the detailed specification of the target core architecture. You can find a sample configuration file armv7.cfg at TQSIM_SRC. Set the ARCH_CONFIG_FILE environment variable with an export command:

export ARCH_CONFIG_FILE=(CUSTOM_DIRECTORY)/armv7.cfg

To launch a test run, do the followings.

  1. Edit .bashrc in your home directory and add the following line:
export PATH=(TQSIM_BIN)/bin:$PATH
  1. change the current directory to (TQSIM_SRC)/example:
cd (TQSIM_SRC)/example
  1. type the command "qemu-arm hello_world"

Note

Current we only support simulation of arm binaries compiled through arm-linux-gnueabi-gcc compiler with "-static" option. Various guest binaries, including x86, x86-64, MIPS, will be supported in the near future.
