According to top-down design process of big hardware design project and extreme complexity of decoding process make it impractical to directly design DOLBY ACS decoding hardware, that is why I devoted myself to successfully designing DOLBY AC3 decoder in system level.
Based on thorough analysis of Intel MCS- 8051 MCU instruction set, the MCU IP soft core's top function definition and structure partition, detailed description of all level modules were finished in the thesis according to the Top-Down high-level design process of digital ASIC system.
The design process and the method for Analyzing and designing electronic circuits with PSPICE are introduced, then comparing to two input method of PSPICE
With the main-current IC product process goes into deep sub-micron, a lot of new design flows arise accompanied with varied IC design tools, especially in the physical application of the back-end design which faces more and more challenges such as: lower consumption, higher work clock speed, smaller die size and shorter tape-out time limit.
A kind of design flows for deep--submicrometer VLSI design is presented in this paper in the background of our reasearch work to a practical VLSI design project. also the basic thought of this method and the actual realization process of the flow are explained in detail. Finally.
In modern deep submicron ASIC design flows, many constraints such as timing, area and load should be set to meet the design goal and the requirements of operation environment. Moreover, all these constraints must be used to drive the EDA tools throughout the design flow .
According to the theory of junction circulator, the paper derives the design formular and poses the design path, and so it designs 2cm band junction circulator.
The patterns of the limiting streamlines on the body surface obtained with the aid of special paints indicate that the calculated design flow scheme is realized in these regimes.
This paper presents the design process of a controller for bandwidth-limited active hydro-pneumatic suspension employed by an off-road vehicle based on co-simulation technology.
This paper presents one MEMS design tool with a total six of design flows, which makes it possible that the MEMS designers choose the most suitable design flow for their specific devices.
The six interfaces are proposed to automatically transmit the design data between every two levels, thus the maximal six design flows could be realized.
The two tools are being used in current design verification flows and have shown that it is possible to seamlessly integrate formal tools into existing design flows.
An automatic tracking loop, an important part of the circuits in automatic searching NMR gaussmeter, is presented in this paper. The tracking rate of this gaussmeter is greater than 0.18T/min with a range of 0.09 to 1.3T. gauss. The mathematical model of this loop is analysed, and its performance specifications and design procedures are also discussed in details. It has been demonstrated that the theoretical analysis is approximately in agreement with the experimental results.
his paper proposes an object-oriented approach concerning data management and tool control to support design engineers for efficient interaction with theirCAD system. A data model named DTO(Data and Tool Object) is offered to characterize a design object which is identified by four aspects: ObjectClass-id, Method, Versionand Facet. A declarative description language is developed for design tool characterization. A dynamic design flow scheduling (DDFS) for tool control is realized with designevent stack mec...
A prototyping tool for fast generation of a graphics user interface on a motif platform is described. A Graphics User Interface AutoGeneration (GUIAG) has been realized by construct ing motif-based widget-trees for the GUI and fast generating motif program codes through source code interpreter. The GUIAG greatly increases programming efficiency. The construction of GUIAG is described and the interface design is illustrated.
