The currently used hardware validation architectures for Application Specific Integrated Circuits intended for automotive Engine Control Unit development are reviewed and a new architecture is proposed. An alternative to hardware validation by different simulation architectures is proposed and analyzed.
Electrical measurement of quantities plays a crucial role in the real world. Measuring voltage is one of the main tasks for developing large number of applications. This paper is focused on design and development of digital voltmeter using different techniques. It has been shown how to develop a Digital Voltmeter (DVM) from simplest type to professional digital voltmeter. Different types of techniques...
We describe the implementation of a real-time control system that manages arrays of pumps, valves and pressure transducers as a subsystem of a simulator for cardiac surgery training. The subsystem is responsible for maintaining an appropriate fluid pressure in the aorta of the heart, and for circulating fluid around the heart, in a manner consistent with a cardiopulmonary bypass machine - both before...
This paper presents IDEA1, a validated SystemC-based simulator for WSNs. It allows the system-level performance evaluation (e.g., packet transmission and energy consumption) with elaborate models of sensor nodes. IDEA1 uses a clock-based synchronization mechanism to support simulations with cycle accurate communication and approximate time computation. Its accuracy has been validated by a testbed...
Wireless Sensor Networks consist of resource-constrained (energy, memory and processing) sensor nodes that are deployed at different locations, in order to monitor physical or environmental conditions. Several limitations exist nowadays, at simulation and at programming level, especially for heterogeneous Wireless Sensor Networks (composed of different hardware devices). Indeed, to optimize a self-organized...
This paper studied about micro controllers interaction using RS232 as a communication tool and C to programming the interaction. PIC18F4520 will be used in this prototype and MPLAB as a software tool. Before run it into the real hardware, some simulation must be done to make sure all the hardware connection and software writing is correct. Proteus 7.1 has been used for the simulation purpose. The...
Microcontrollers are widely applied in the field of industry to solve engineering control problems. The increased use of microcontrollers makes microcontroller course necessary for electricity related speciality. A new simulation software package for microcontroller, Proteus virtual system modelling (VSM), is introduced for industrial and educational use. Proteus VSM combines circuit simulation, animated...
Software chip is designed to present a study software platform without support of hardware entity by simulating hardware chip operating function. The paper introduces the concept of software chip, and presents software chip design methods. When designing a software chip, specific and related things or controls are chosen to substitute for the abstract functions of the chip, and signal flow trend and...
Recent developments in microcontroller, radio transceiver, and energy harvesting device design now permit wireless sensor nodes to operate indefinitely from power scavenged from their environment. Many algorithms for conventional sensor networks assume that nodes run directly from non-rechargeable batteries and therefore attempt to conserve energy rather than carefully exploiting it when available...
