Synthesis user-defined types

To implement a data select in the Workbench synthesis tools, a new type of multiplexor was needed whose select lines may be connected to arbitrary data values in the data path. This was implemented through the use of user-ops, a means of describing user-defined operations. This capability essentially extends the operator set of the VT and lets the user assign special purpose hardware to these nodes. This feature allows for experimentation with behaviors that have extended operator sets. In this case, we defined a new type of multiplexor whose select inputs are not connected to the controller. The new data-selected-multiplexor is treated just as any other combinational resource. 

Resource libraries generally fall into two types. The first are those that are predefined and provided by synthesis tool or CAE vendors. These primarily contain package declarations and bodies of the sort described in section 3.4.1. The second type are user defined. These may be previous circuit designs which have design tmits that are common to the present one or simply contain declarations that the designer frequently uses. User-defined libraries may therefore contain not only packages but also entities and architectures. 

Taking into account the conclusions of the analysis of literature study area (reliability system) was assumed to have not been shown explicitly complex mathematical relationships that could be used to estimate the state of airworthiness man-machine system. There are grounds to conclude that the commonly used commercial solutions and research and implementation for many years used a piecemeal approach to achieve and maintain the declared level of airworthiness technical object (the system and its component) for continuoustime ability to implement services. The attention is focused on the analysis and synthesis of selected aspects of the research problem. Not defining numerical indicators and not taking into account technical and functional capabilities CTS and the effects of the conditions and environmental exposures and human origin. In addition, notes the lack of a clearly definite influence are methods of access to the system, data transport mechanisms and guarantee the level characteristics (i.e., reliability, safety, quality, efficiency, etc.) are important from the point of view of the system and the user who is the recipient of its products. This type of approach, particularly in the structures of the system, is focused on one or a few acquaint criteria.
