    Abstract
    PLD and CPLD has been extensively used for custom made circuits. That is why they are perfect for designing traffic light control systems. Our thesis represents the performance comparison of a traffic light control system designed on GAL (Generic Array Logic) using Programmable Logic Device (PLD) and on FPGA (Field Programmable Gate Array) using Complex Programmable Logic Device (CPLD). For our PLD implementation, we have considered GAL (16V8) chips, which can be reprogrammed and erased. For the CPLD implementation, we have considered FPGA (Altera's Flex 10k family's EPF10K10TC144-4) chip, which is a 144 pin SRAM. The CPLD design was developed using the CPLD programming software MAX PLUS2 v 9.23. The traffic light controller consists of traffic signals (Red, Yellow/Amber & Green). We have designed the traffic controller using both CPLD and PLD. Then we have taken the real time waveform as well as the simulated waveform for different frequencies. The Digital Storage Oscilloscope (DSO).was used to generate the real time wave from the traffic controllers. The results from the real time waveform clearly illustrates that CPLD has the better performance over the PLD technology. Further more we have designed complex circuits for automated detection of railway crossing and A Five road junction ontrolling Traffic light system.
