The developer prepares the TOE description, including its concise presentation for consumers. It contains the following kinds of data identifiers, product type and functionality, logical and physical boundaries and the TOE operational environment. 

Adjustability design for different demands of the functional logic of order processing, e.g., order generation or release algorithm, and/or weight of the PPC targets. 

Innate and guided C—H functionalization logic (functionalization of N-heterocycles, in particular, alkaloids) 12ACR826. 

In other articles, the so called RFLP approach, that stands for Requirements, Functional, Logical and Physical modeling, is presented as a procedural model for Systems engineering. In fact, the RFLP approach is approximately equivalent to the descending side of the V model, which it includes. It highlights the fact of creating a functional model out of requirements engineering, whereby the main function is decomposed into sub-functions that can spread over many hierarchical levels.

A library of AltaRica nodes was developed in order to help building safety models for avionics platform architectures. This library includes AltaRica nodes that describe functional, logical and physical nodes. The library was used in order to develop safety models to assess the safety of Integrated Modular Avionics [9]. In this type of architecture, computation or communication resources are shared by several functions or data flows. Consequently, the fault of a shared physical node has an impact on all logical and functional nodes that are connected with this physical node. For instance, in the previous figure, data flows DataFlowla and DataFlowlb are connected to the same physical node called Phy Iteml. So if Phy Iteml is lost then both data flows would be lost. 

In designs where a functional port is shared with a scan-out port, TC synthesizes a mux to select between the last scan cell in the scan chain and the functional logic. The scan-enable signal is connected to the select line of the mux such that when the scan-enable is active, the last scan cell is selected. Since the scan-enable is generally inactive in most patterns to capture faults on the data path, a separate scan-out strobe cycle is required. 

In this paper, we refer in particular to physical interdependencies, cyber interdependencies and also logical interdependencies. In other words, we describe the situation for which one subsystem needs the resources such as power, control signal, water and so on, from another subsystem to keep its functionality. Logical interdependencies can also... 

Procedure for analysis of RFT Step 1 Construct a RFT based on system configuration and functional logic. 

On the other hand, and in order to assure a representative model of the system, they must consider the functional logic of the system, so in this way the model can stop the hour meters represented meanwhile the detentions of the system are produced. 

Therefore, the foot- and handbrakes (see Figs. 4.5 and 4.6) as well as the front wheel and rear-wheel brake are only deployed once. If now also the foot pedal affects the parking brake, we can see that the function for both actuator have to generate different signals, or the function logic behind it has to interpret those signals differently. 

The interfaces become multi-dimensional a functional, logical or technical view to an interface will provide different information about the interface. Until now, we only had to consider functional interfaces. Now, the interfaces of technical elements (see Fig. 4.26) overlap and raise new challenges or cannot implement the required characteristic by themselves but possibly together with other elements. 

System design is therefore the illustration of technical characteristics and components, from which the system is composed. The system design specification describes the characteristics, which result from the interfaces of components. The components can also be made of functional, logical or technical elements and have characteristics that result from the interfaces of these elements. These elements need to be specified as well. 

Electronic design is therefore the illustration of technical characteristic of electronic elements (components, electronic parts), of which an electronic system is comprised. The electronic design specifications describe characteristics, which result from the interaction of electronic elements. The electronic elements can consist of functional, logical or technical elements and have characteristics, which result from the interaction of these elements. These mechanical elements need to be specified as well. This would in general be done within the component specification. Electronic components consist of electronic elements (parts are the smallest elements for discreet electronic, for semiconductor sub-parts are defined as logical or functional units to sufficiently describe the behavior and the relevant characteristics), whereas the combination and the selection, which elements belong to the component, represent a design decision (Fig. 4.69). 

Common boundaries Items that share a common boundary (physical, functional, logical, etc.) may have CCF vulnerabihties.
