cell

I've got a massive Excel 2003 spreadsheet I'm working on. There are a lot of very large formulas with a lot of cell references. Here's a simple example. ='Sheet'!AC69+'Sheet'!AC52+'Sheet'!AC53)*$D$3+'Sheet'!AC49 Most of them are more complicated than that, but this gives a good idea of what I'm working with. Few of these cell references are absolute ($s). I'd like to be able to copy these cells to a different location without the cell references changing. I know I can simply use f4 to make the references absolute, but there is a lot of data and I may need to use Fill later. Is there any way to

为什么要引入AOCV 为了精确性，为了剔除悲观度。用set_timing_derate来设置OCV，对于一个固定的corner，只能对data/clock, cell/net, late/early分别设不同的值，由下图可知，这个值是个trade off的结果，在保证yield的前提下，尽量不那么悲观，但由于其『固定天性』，这个值既不能cover最悲观的部分，而对另一部分又过于悲观。 什么是AOCV AOCV是一种用伪统计（pseudo-statistical ）来模拟variation的方法，相对于传统OCV更精确，它用于模拟random 和systematic variations： Systematic variation： 即Distance based AOCV，用于模拟global variation，根据芯片制造过程的统计特性，距离越远的cell之间相对的variation越大，所以用distance based AOCV来描述距离跟derate之间的关系，距离越大derate越大，这个距离是指一条timing path所在『物理范围』内对角线的长度。timing path的位置信息由SPEF提供，这要求抽SPEF时需要将坐标信息抽出，在STA中读SPEF时要把SPEF的坐标读入。 Random variation： 即Depth based AOCV

I am working on an worksheet generator in Excel 2007. I have a certain layout I have to follow and I often have to format cells based on input. Since the generator is dynamic I have to calculate all kinds of ranges, merge cells, etc. How can I convert values like this? Cells(1,1) into A1 and vice versa The Address property of a cell can get this for you: MsgBox Cells(1, 1).Address(RowAbsolute:=False, ColumnAbsolute:=False) returns A1 . The other way around can be done with the Row and Column property of Range : MsgBox Range("A1").Row & ", " & Range("A1").Column returns 1,1 . 来源： https:/

I have an excel Sheet1 of a thousand of rows and 20 columns from A1 to T1. Each cell in that range has some data in it, usually one or two words. In Sheet2, A1 column I have a list of data of 1000 values. I am working on VBA script to find words from Sheet2 list in Sheet1 and clear the values of the cells of the found ones. I now have a VBA script that works only on A1 column of Sheet1 and it deletes the rows only. Here's the script: Sub DeleteEmails() Dim rList As Range Dim rCrit As Range With Worksheets("Sheet1") .Range("A1").Insert shift:=xlDown: .Range("A1").Value = "Temp Header" Set rList

主要有： 位示图 和内存的位示差不多 空闲块表 和可变内存管理差不多 空闲块链 主要是UNIX成组链接法的设计与实现 UNIX系统文件管理成组连接算法说明 UNIX系统文件管理成组连接算法： 把空闲块分成若干组，把指向一组中各空闲块的指针集中一起。 这样既可方便查找，又可减少为修改指针而启动磁盘的次数。 UNIX系统：采用空闲块成组连接的方法。 UNIX系统把每100个空闲块作为一组，每一组的第一个空闲块中登记下一组空闲块的块号和空闲块数， 余下不足100块的那部分空闲块的块号及块数登记在一个专用块中，登记最后一组块号的那个空闲块其中第2个单元填“0”， 表示该块中指出的块号是最后一组的块号，空闲块链到此结束。 系统初始化时先把专用块内容读到内存，当需分配空闲块时，就直接在内存中可找到哪些块强障械模糠峙湟豢楹蟀芽障锌槭。 但要把一组中的第一个空闲块分配出去之前应把登记在该块中的下一组的块号及块数保存到专用块中。 当一组空闲块被分配完后，则再把专用块的内容读到内存，指出另一组可供分配的空闲块。当归还一块时， 只要把归还块的块号登记到当前组中且空闲块数加1。如果当前组已满100块，则把内存中的内容写到归还的那块中， 该归还块作为新组的第一块。假设初始化时系统已把专用块读入内存L单元开始的区域中，分配和回收的算法如下： 分配一个空闲块 查L单元内容（空闲块数）： 当空闲块数1 i

I'm encountering an issue with certain iOS web pages (in both mobile Safari, Chrome, and in also iOS Webviews in app) over cellular data vs. Wifi, The issue is identical to what was previously posted by someone else here: Mobile Safari Cellular Only Loading Error Unfortunately no answers yet posted to the above URL. Basically, I'm consistently seeing extraneous random garbage characters in the HTML that comes down from cellular data, but the same page loading perfectly okay via Wifi. This isn't a download speed or poor connection issue, it seems to be some inexplicable data transfer

如何debug 一颗cell 或一段net 的delay, 常用的办法是用report_delay_calculation 报这颗cell 或这段net, 会得到形式如下的report, 从该report 中可以得到： 表头需要特别关注的是command, 确定report 的对象及加的option; From/To pin: cell 的input pin 和 output pin; Cell: 该cell 对应的lib cell; Library: 该cell 来自哪个lib, 需要特别关注一下，确定用的lib 正确，避免低级错误； Arc sense: Arc sense 分三种positive unate, negetive unate, non unate; 输出信号同输入信号跳变方向相同的称为positive unate 如buffer 的timing arc; 输出信号同输入信号跳变方向相反的称为negetive unate 如inverter 的timing arc; 输出信号的跳变方向由另一个输入信号的值决定称为non unate 如xor 的timing arc; Delay type: 标示是cell delay 还是net delay; Base or SI: 因为加了option -si, 所以当前是SI delay; RC summary for net
