Different design approaches were compared and finally one approach was implemented. Each individual module was designed separately. After successful simulation and testing, they were put together to create the finalized version. Each individual module was designed separately. After successful simulation and testing, they were put together to create the finalized version (Figure 2). Regulator Voltage regulator ICs are available with fixed (typically 5, 12 and 15V) or variable output voltages. They are also rated by

Design Lab, Use these chips often in their laboratory. The IC to be tested should be placed on the ZIF socket and the Microcontroller prompts the user to enter the IC number of the chip to be tested. After entering it the microcontroller will check the IC as per the truth table of the IC which is stored in its ROM. It will check each and every pin of the IC and produce the Output detail. Like “Gate 1 is good”, “Gate is bad”, “Counter 1 is good” etc The Logic gate tester is used to test integrated circuit logic ICs. We don’t need to rig up different kinds of circuits for different kind of logic ICs, each time we need to test them. The chip tester verifies the functionality and timing of some variety of 7400 series logic gate integrated circuits. Students taking Digital Logic

The object code file cannot be executed on the target microcontroller. It needs to be passed through a program called a linker. The job of the linker is to take the object file produced by the assembler and link it with standard library modules (that have already been pre-assembled into object files) to produce a complete working executable file that can be loaded into the memory of the microcontroller. Sometimes the assembler and linker are combined into one program so that assembling a source program automatically links it as well. This is the case with the 8051 Assembler.
