Mixed-Signal Integrated Systems: Limitations and Challenges
Published in Tertulien Ndjountche, CMOS Analog Integrated Circuits, 2017
The functional description is realized by an analog circuit and a digital circuit, which can be designed and verified using various computer-aided design programs such Cadence, Synopsys, and Mentor Graphics tools. When the data processing in the digital domain may require processors or microcontrollers, the design of a real-time operating system (RTOS), application software and device driver is necessary. Besides allowing a modular and scalable programming approach, the desirable features of an RTOS include the ability to provide basic support for task scheduling, resource management, inter-task and input-output communication such that the processor functionality is available to application software in an optimized and predictable way. Stateflow is an interactive design and simulation tool that can be used to describe complex logic, such as an RTOS, in a form that can easily be coded using C/C++ language or assembler.
®: Creating Finite State Machine Models

Absence of syntax errors cannot ensure the fault-free operation of Stateflow diagram because the diagram can contain semantic errors, which are more serious. Stateflow has the debugging means for semantic error detection, and offers the possibility of step-by-step tracing of the Stateflow diagram execution logic; animation can be used to upgrade the operation pictorial information.

In this paper, a new multi agent platform called Stateflow is introduced to analyze the performance of multi agent system based microgrid energy management. Stateflow is an environment that utilizes the concept of state machines and flow charts for modeling and simulating the decision logic and controls. The Stateflow enables to model, how a system responds to particular conditions, events, and external factors, etc. A state machine represents a system that is driven by some events, and which can make the transition from one mode to another mode according to the changes in the environment. State machines are the best known and classical method of modeling the behavior of any system [29]. State machine allows designers to imagine the state of any system at a particular point of time and also describe the behavior of the system based on that state. Moreover, this modeling method is not limited to the software system [30]. Mathematically, a finite state machine can be defined as [31]: where ϵ- Finite inputs to the machine, Q- Finite set of states, - Initial states, - Final states, and - Transition function.
