3. Development Environment
1. MATLAB R2011b，Simulink :
This tool is used to design a Model-Base RTL circuit.
2. Synplify Premier with DP F-2011.09-SP1-1 :
This tool is used to transform a circuit described HDL to edf file.
3. Xilinx EDK(Embedded Development Kit)：
This tool is used to MicroBlaze and to design software. This tool has two functions; which are XPS and
SDK. XPS is used to design HW circuit, and SDK is used to design SW.
4. Xilinx ISE13.2:
This tool is used to create bit-streams; which is used to design all of circuit and to write circuit into
FPGA.
