Testing plans

• Engine emulator (Lab-View)

What is left

• Printing the board• Designing the computing unit

DE-2• Integration• Testing

tasks for next semester

• Building the testing environment. Learning the DE-2 & VHDL

• Learning previous projects work• Building our design in VHDL

while testing the PCB• Printing to DE-2 & verification• Integration• Testing the whole system

Thank you
