Abstract-This project emphasized mainly on software analysis. Modelsim-Altera 6.4a is the software that used to generate every single module of the Built-in-Self-Test (BIST) for Random access Memory (RAM) architecture. There are three key things to be concern in the BIST for RAM which is the Test Pattern Generator (TPG), Output Response Analysis (ORA) and RAM. The output of counter which is a type of TPG is analyzed to provide a pattern for March test algorithm. At the mean time, the ORA compare the output from decoder and the RAM output itself which modeled under the theory of numerical autonomy of error vectors from the circuit under test. The output of ORA, the comparator, will show pass or fail for faulty detection of RAM. The system has been successfully developed and vector waveform is used to examine the result of the system. From the result obtained, it showed that the system is working as expected with satisfactory result.
This paper proposed a design of a modern FPGA-based Traffic Light Control (TLC) System to manage the road traffic. The approach is by controlling the access to areas shared among multiple intersections and allocating effective time between various users; during peak and off-peak hours. The implementation is based on real location in a city in Malaysia where the existing traffic light controller is a basic fixed-time method. This method is inefficient and almost always leads to traffic congestion during peak hours while drivers are given unnecessary waiting time during off-peak hours. The proposed design is a more universal and intelligent approach to the situation and has been implemented using FPGA. The system is implemented on ALTERA FLEX10K chip and simulation results are proven to be successful. Theoretically the waiting time for drivers during off-peak hours has been reduced further, therefore making the system better than the one being used at the moment. Future improvements include addition of other functions to the proposed design to suit various traffic conditions at different locations.
