### DRAMSys Thermal Simulation
Before starting make sure you have a **clean repository** without any previous
automatic generated Makefiles. One way to ensure this is by running the
command below inside your DRAMSys repository, but keep in mind that
**untracked files and directories will be removed** from the repository.
``` bash
$ git clean -fdx
```
This feature can be enabled via an environment variable.
``` bash
$ export THERMALSIM=true
$ qtcreator &
```
or
``` bash
$ mkdir build
$ cd build
$ export THERMALSIM=true
$ qmake ../DRAMSys/dram.vp.system.pro
$ make
```
The thermal simulation is performed by a **3D-ICE** [8] server accessed
through the network. Therefore users interested in thermal simulation during
their DRAMSys simulations need to make sure they have a 3D-ICE server up and
running before starting.
More information about how to obtain 3D-ICE and how to intall it can be found
in the official website http://esl.epfl.ch/3D-ICE.
Provided the user fulfilled this installation requisite, before starting
DRAMSys it is necessary to run the 3D-ICE server passing to it two arguments:
a suitable configuration file and an Internet socket port number. And then
wait until the server is ready to receive requests.
``` bash
$ 3D-ICE-Server <stack file> <port>
Preparing stk data ... done !
Preparing thermal data ... done !
Creating socket ... done !
Waiting for client ... done !
```
The IP address and the port number related to the server shall be informed in
DRAMSys' configuration to subsequent use by DRAMSys to access the thermal
simulation server.
#### Usage Example
The DRAMSys' main configuration file is presented below.

```
Generate the input trace file for DRAMSys.
``` bash
$ cd DRAMSys/tests/error/
$ ./generateErrorTest.pl > test_error.stl
```
Start the 3D-ICE server providing the stack file and the port number.

$ cd DRAMSys/simulator/resources/configs/temperature_sim
