Written entirely in synthesizable vhdl 模型全綜合設(shè)計
Together, in this part coding the reusable and synthesizable code was deeply discussed . lastly, fpga is used to test the function of the system 同時,在這部分還對可復(fù)用可綜合代碼的編寫做了比較深入地研究與探討。
We describe this architecture synthesizable with veriloghdl langrage in fpga . according to the specification of the fpga, we chose the optimal multiplier and adder 我們用veriloghdl對這種結(jié)構(gòu)進行基于fpga實現(xiàn)的可綜合的描述,并結(jié)合fpga的特點選擇了最佳的乘法器和加法器的設(shè)計。
3 ) the paper discussed the theory and the method of asic high-level synthesis : ? nalyzed the synthesizable problems of vhdl language systematically, and discussed the establishment and the implementation methods of vhdl synthesis subclasses 3)本文對asic高級綜合的理論與方法進行了深入的探討:系統(tǒng)地分析了vhdl語言的可綜合性問題,并探討了vhdl綜合子集的確立及實現(xiàn)方法。
The thesis researches on the methodology for energy efficient soc design . soc has several design levels according to the design flow . the thesis covers on the higher levels including system level, software level, and synthesizable logic level 本文主要從可綜合的邏輯層以上的設(shè)計層次來進行soc低功耗設(shè)計方法論的研究,這些層次與工藝無關(guān),包括系統(tǒng)設(shè)計、軟件設(shè)計和可綜合邏輯設(shè)計層次。
The whole system is divided into several modules and each module is connected by signals, which based on the arithmetic of spwm and the requirement of design . the module design is to design inner circuit structure of each module and uses verilog language to code the synthesizable and reusable code . the functional stimulation uses the nc-verilog of cadence 系統(tǒng)設(shè)計是基于spwm的實現(xiàn)算法和設(shè)計指標要求,對系統(tǒng)劃分模塊和對各個模塊進行信號連接;模塊設(shè)計是設(shè)計每個模塊內(nèi)部電路結(jié)構(gòu),并用verilog語言編寫可綜合可復(fù)用代碼;功能仿真使用的工具是cadence的nc_verilog,首先對每個模塊進行功能仿真,仿真通過之后,把所有模塊代碼組合在一起,構(gòu)成整個系統(tǒng)代碼,在外部輸入端口加激勵,對整個系統(tǒng)進行功能仿真。
