In this work, our focus is on study and analysis of power and junction temperature at different temperatures and at different capacitance values. Kintex7 is 28-nm FPGA on which we implement our circuit to re-assure power reduction and reduction in junction temperature in sequential circuit. Varying the values of capacitance and temperature enhance the efficiency of the Energy Efficient Traffic Light Controller design. This paper basically deals with FSM (Finite State Machine) and is implemented on FPGA. FGPA is preferred because of its high speed and is inexpensive. Traffic lights are beneficial in managing the traffic, reducing accidents rate, relaxing traffic cop’s job, minimizing fuel consumption and emission and save time. The performance of our energy efficient traffic lights is evaluated and tested through simulations on Xilinx software development kit. For 2.4GHz operating frequency, there is 47.71% reduction in total power dissipation, 69.94% reduction in IOs power dissipation, and 0.78% reduction in junction temperature when we use 28nm FPGA and temperature is 25 degree Celsius and capacitance is scaled down from 100pF to 20pF. For 10GHz operating frequency, there is 54.81% reduction in total power dissipation, 70.11% reduction in IOs power dissipation, 3.52% reduction in leakage power dissipation and 1.92% reduction in junction temperature when we use 28nm FPGA and temperature is 50 degree Celsius and capacitance is scaled down from 100pF to 20pF.
