This design for mvbc system adopts top - down eda common design flow. circuit design adopts veriloghdl coding description. function simulation and timing verification adopt simulation tool vcs of synopsys inc, the logic synthesis tool and fpga programming tool adopt the quartus ii of altera inc, and the fpga advice stratix ii ep2s15
該mvbc系統設計採用業界通用的自上而下的eda設計方法，電路邏輯實現採用veriloghdl硬體語言描述，功能和時序驗證的動態模擬採用synopsys公司的vcs ，而邏輯綜合與fpga實現採用altera公司的集成開發環境quartusii軟體以及stratixiiep2s15的fpga器件。 -
The paper begins with the research of the organization ' s current state and available resource, then demonstrates the necessity and feasibility of system development, puts forward the objective and task of the system by the analysis of whole system, fixs on this system ' s main function and structure by the structured method of top - down and delicatilization step by step, and finally uses the object oriented programming to make the concrete design
本文從系統的現行狀態和可用資源的調查入手，論證了系統開發的必要性和可行性，通過對整個系統的分析，提出了系統的目標和任務，運用自頂向下、逐步細化的結構化方法確定了系統的主體功能和結構，最後運用面向對象的程序設計方法（ oop ）進行了具體的設計。 -
In the light of the method of top - down, the author put forward the concept of product function structure tree, which was used to express the product ' s function structure during the conceptual design. based on it, the product structure was expressedthe paper studies the definition of the function model which supports the method of top - down design, and the expression of function model based on binary - tree was also put forward in the thesis. for the abstract description of parts in the assembly level and the integration with other systems during the whole life circle of the products, the concept of assembly model was presented, the definiton, classfication and expresstion method of assembly feature was studied in this thesis. the representation of assembly relationship and data structure of the assembly model based on diagram was further studied. for the constraints transfer between function model and assembly model, an hierarchical component model is presented. an arithmetic of the change of assembly relationship when assembly model changing was also studied. fmally, a system named fb - tpms, which using object oriented programming technology and pro / toolkit, was developed
為了支持在裝配層次上的零件的抽象建模，提出了骨架模型的概念，並討論了裝配模型的建立方法。根據前述裝配模型有關研究，探討了從功能模型到裝配模型以及從上一級裝配模型到下一級裝配模型的數據和約束傳遞問題，並用層次化單元裝配模型得以解決，同時提出了裝配模型變動時引起的裝配關系的變化的有關演算法。在論文的最後部分用用面向對象的程序設計方法，結合課題要求，研究了支持自頂向下設計方法的裝配建模系統fb - tpms 。 -

First, study the concept and the key technology for dfc and analyze every factor influencing the products " cost within the products " life cycle ; second, set up the estimating model of products " cost based on the function to meet the modem products " design idea of the " top - down ", unifying the products " cost and structure on this functional concept ; third, based on the functionally estimating model of the products " cost, propose two grades of products " cost estimating method based on the function. the method can be used in the cost " estimation in the whole course of product design ; finally, regarding solidworks as the developing platform, delphi as the programming tool, structure a based on function - based products " cost estimating system to tentatively prove the practicability and feasibility of this text ' s estimating method
第一，研究面向成本設計的概念和關鍵技術，面向產品全生命周期分析影響產品成本的各項因素；第二，建立基於功能的產品成本估算模型，以適應「自頂向下」的現代產品的設計理念，將產品成本與產品結構在功能這一概念上得到統一；第三，在基於功能的產品成本估算模型的基礎上，提出了基於功能的產品成本兩級估算方法，此方法可用於產品設計全過程中產品成本的估算；最後，以浙江工業大學碩士學位論文摘要solidworks為開發平臺， delphi為編程工具，初步構建了基於功能的產品成本估算系統，驗證了本文估算方法的實用性和可行性。 -
