+
+To build the JAVA program: (for kernel and Manager (.maxj))
+
+$ cd starpu/tests/
+$ maxjc -1.7 -cp $MAXCLASSPATH fpga
+
+To run the Java program to generate a DFE implementation (a .max file)
+that can be called from a StarPU/FPGA application and slic headers
+(.h) for simulation:
+
+$ java -XX:+UseSerialGC -Xmx2048m -cp $MAXCLASSPATH:. fpga.StreamFMAManager DFEModel=MAIA maxFileName=StreamFMA target=DFE_SIM
+
+$ cp StreamFMA_MAX5C_DFE_SIM/results/*{.max,.h} fpga
+
+$ cd fpga
+
+To build the slic object file (simulation):
+
+$ sliccompile StreamFMA.max
+
+To start the simulation:
+
+$ maxcompilersim -c LIMA -n $USER-StreamFMA restart
+$ export LD_LIBRARY_PATH=$MAXELEROSDIR/lib:$LD_LIBRARY_PATH
+$ export SLIC_CONF="use_simulation=$USER-StreamFMA"
+
+PS: To stop simulation
+
+$ maxcompilersim -c LIMA -n $USER-StreamFMA stop
