基本的編輯工具(GENERAL EDITING FACILITIES)
對象放置(Object Placement)
ISIS支持多種類型的對象，每一類型對象的具體作用和功能將在下一章給出。雖然類型不同，但放置對象的基本步驟都是一樣的。
放置對象的步驟如下(To place an object:)
1.根據對象的類別在工具箱選擇相應模式的圖標(mode icon)。
2. Select the sub-mode icon for the specific type of object.
2、根據對象的具體類型選擇子模式圖標(sub-mode icon)。
3、如果對象類型是元件、端點、管腳、圖形、符號或標記，從選擇器里(selector)選擇你想要的對象的名字。對于元件、端點、管腳和符號，可能首先需要從庫中調出。
4、如果對象是有方向的，將會在預覽窗口顯示出來，你可以通過點擊旋轉和鏡象圖標來調整對象的朝向。
5、最后，指向編輯窗口并點擊鼠標左鍵放置對象。對于不同的對象，確切的步驟可能略有不同，但你會發現和其它的圖形編輯軟件是類似的，而且很直觀。
選中對象(Tagging an Object)
用鼠標指向對象并點擊右鍵可以選中該對象。該操作選中對象并使其高亮顯示，然后可以進行編輯。
Nios II定制指令用戶指南：With the Altera Nios II embedded processor, you as the system designer can accelerate time-critical software algorithms by adding custom instructions to the Nios II processor instruction set. Using custom
instructions, you can reduce a complex sequence of standard instructions to a single instruction implemented in hardware. You can use this feature for a variety of applications, for example, to optimize software inner
loops for digital signal processing (DSP), packet header processing, and computation-intensive applications. The Nios II configuration wizard,part of the Quartus® II software’s SOPC Builder, provides a graphical user interface (GUI) used to add up to 256 custom instructions to the Nios II processor.
The custom instruction logic connects directly to the Nios II arithmetic logic unit (ALU) as shown in Figure 1–1.
This document was developed under the Standard Hardware and Reliability Program (SHARP) TechnologyIndependent Representation of Electronic Products (TIREP) project. It is intended for use by VHSIC HardwareDescription Language (VHDL) design engineers and is offered as guidance for the development of VHDL modelswhich are compliant with the VHDL Data Item Description (DID DI-EGDS-80811) and which can be providedto manufacturing engineering personnel for the development of production data and the subsequent productionof hardware. Most VHDL modeling performed to date has been concentrated at either the component level orat the conceptual system level. The assembly and sub-assembly levels have been largely disregarded. Under theSHARP TIREP project, an attempt has been made to help close this gap. The TIREP models are based upon lowcomplexity Standard Electronic Modules (SEM) of the format A configuration. Although these modules are quitesimple, it is felt that the lessons learned offer guidance which can readily be applied to a wide range of assemblytypes and complexities.
Field Programmable Gate Arrays (FPGAs) are becoming a critical part of every system design. Many vendors offer many different architectures and processes. Which one is right for your design? How do you design one of these so that it works correctly and functions as you expect in your entire system? These are the questions that this paper sets out to answer.

VHDL 關于2DFFT設計程序
u scinode1 ∼ scinode9.vhd: Every SCI node RTL vhdl code. The details can be
seen in the following section.
u 2dfft.vhd: The top module includes these scinodes and form a 3x3 SCI Torus
network, and it support these sub-modules scinode1∼ scinode9 reset and clk
and global_cnt signals to synchronous the sub-modules to simplify the overall
design.
u proj2.wfc: VSS simulation result that is the same as the ModelSim simulation
result.
u Pro2_2.wfc: VSS simulation result of another test pattern can’t cause overflow
situation.
Although there has been a lot of AVL tree libraries available now, nearly all of them are meant to work in the random access memory(RAM). Some of them do provide some mechanism for dumping the whole tree into a file and loading it back to the memory in order to make data in that tree persistent. It serves well when there s just small amount of data. When the tree is somewhat bigger, the dumping/loading process could take a lengthy time and makes your mission-critical program less efficient. How about an AVL tree that can directly use the disk for data storage ? If there s something like that, we won t need to read through the whole tree in order to pick up just a little bit imformation(a node), but read only the sectors that are neccssary for locating a certain node and the sectors in which that node lies. This is my initial motivation for writing a storage-media independent AVL Tree. However, as you step forth, you would find that it not only works fine with disks but also fine with memorys, too.
his folder contains the following files:
1. 02490rxP802-15_SG3a-Channel-Modeling-Subcommittee-Report-Final.doc: This is the final
report of the channel modeling sub-committee.
2. cmx_imr.csv (x=1, 2, 3, and 4) represent the files containing the actual 100 channel
realizations for CM1, CM2, CM3, and CM4. The columns are organized as (time, amp, time, amp,...)
3. cmx_imr_np.csv (x=1, 2, 3, and 4) represent the files containing the number of paths in
each of the 100 multipath realizations.
4. cmx_imr.mat (x=1, 2, 3, and 4) are the .mat files that can be loaded directly into
Matlab (TM).
5. *.m files are the Matlab (TM) files used to generate the various channel realizations.
