ODE solver controlled by NIOS II soft processor that I used to simlaute a spring mass damper system

The system consistes of 3 main blocks

• ODE solver to numercally calculate the responce of spring-mass-damper system (2nd order ODE)
• NIOS II processor with JTAG-UART IP & PIOs that will be programmed to provied inputs through a NIOS II terminal opend in host PC
• VGA interface to output system's responce

the system used 2_16 fixed point repersntaion

Design procedure

• Simualting hardware using MATLAB

• Designing the solver in verilog HDL

• Simulating the verilog module using ModelSim until MATLAB outputs matched Verilog module output

• Addind NIOS II core, JTAG UART & PIOs using Intel platform designer and genratin the HDL
• Integrating the system

- Codeing the C program for the NIOS II to configure the ODE-Solver inputs
