The automatic schematic diagram generator of BIT (ASG-BIT) discussed here is a subsystem of the VHDL high-level synthesis and mixed-level simulation system (HLS-BIT). It can abstract netlists from the result of logic synthesis and generates functionally readable and aesthetically pleasing diagrams within reasonable execution time. The partitioning, placement and routing of schematic diagram are discussed .and some results including several diagrams generated by ASG-BIT system are presented in the finale of this paper. 展开更多

With this proposal a discrete situation is replaced by a fuzzy one. There are identified certain advantages concerning the use of the bar as compared to that of a scale during both the stages of filling-in as well as processing a questionnaire. The main advantage associated with business research requirements is the fact that it is expected to be much quicker to fill in and much easier to explain to participants. The bar provides the potential for different types of processing Likert scales cannot. Therefore the researchers are allowed to ascertain that the given answers follow not only the already suggested and used Gauss distribution but also a parabola distribution as it will be suggested in present paper, and which is expected to give the researcher the opportunity to "correct" this tendency. Therefore, a possibility of choosing amongst a number of alternatives is offered, by utilizing fuzzy logic in the same way as it has already been done in industry and combining mathematical models with multivalued operations. 展开更多
