第一篇:ICC使用小结

ICC使用小结

(1)ICC的输入文件

MilkyWay(physical library),TLUPlus文件(interconnect文件),lib文件(logical library),netlist,constraints(sdc),floorplan文件(.fp或.def)

由于ICC会使用MilkyWay数据格式,因此有必要先熟悉MilkyWay格式的产生。

(2)ICC的步骤流程

ICC的流程如下:(1)import design(netlist/sdc/database)——(2)create_floorplan或adjust floorplan——(3)placement ——(4)cts——(5)route——(6)final signoff(3)具体每一步过程及注意点(操作点)(4)Import design具体操作:

set_link_library xxx set_target_library xxx create_mu_lib design_library –technology xxx.tf –mw_reference_library ref_library open set_tlu_plus_file –max_tluplus max_file –min_tluplus min_file –tech2itf_map map_file read_verilog xxx.v current_design xxx link read_def xxx.def derive_pg_connection –power_net xxx_power_net –power_pin xxx_power_pin –ground_net xxx_ground_net –ground_pin xxx_ground_pin derive_pg_connection –power_net xxx_power_net –power_pin xxx_power_pin –ground_net xxx_ground_net –ground_pin xxx_ground_pin-tie read_floorplan xxx.fp或新创建一个floorplan接下来的任务了。

(5)Create_floorplan具体操作:

Create_floorplan针对读入的设计以及def,开始进行floorplan的规划,包括IO以及macro的摆放,电源规划等。

首先要创建一个floorplan,创建floorplan之前需要读入IO的约束信息,3101项目将IO视作macro对待。具体的io constraint信号可以使用set_pad_physical_constraints来设置。

Create_floorplan –control_type width_and_height –core_width xxx –core_height xxx Remove_terminal *-keep_macro_place –keep_std_cell_place,只有设置了keep之后,才能create_fp_place完成,否则会报utility超出。

设置好floorplan之后就需要对macro和standcell进行place了。Macro的place可以使用脚本set_obj*和set_attribute来设置,而standcell可以使用create_fP_placement来完成。这个过程中先需要设置placement以及route的blockage。create_place_blockage和create_route_guide来完成blockage的设置。

接着设置在Design Planning的task任务下,进行place macros和standcells。或者使用create_fp_placement –timing_driven –no_hierarchy_gravity 设置完macro和standcell之后,就可以进行电源规划了,可以通过产生power_ring或power_strap来进行。create_power_strap –direction horizontal –net {VDD12 VSS_PAD} –layer M5 –configure step_end_stop –start_at 1290 –stop 2170 –step 50 –width 5 –start_low_ends coordinate –start_low_ends_coordinate 583 –start_high_ends coordinate –start_high_ends_coordinate 1710 –extend_low_ends off –extend_high_ends off –keep_floating_wire_pieces –ignore_parallel_targets –define_parallel_targets_by_wire_directions 下面对上面这个strap的创建进行解释说明下,上面的power_strap表示要在位置区域为{{1290 583} {2170 1710}}的方形区域创建间距为50,线宽为5的水平方向power_strap。

(6)placement的具体操作

place_opt进行之前需要先查看report_constraints –all看看主要的violation是哪些,同时也应该查看congestion情况以选择合适的place_opt策略。也需要检查设计及物理信息,check_physical_design –for_placement以及check_design –physical,设置set_ignore_layers –max/-min,接着create_placement –timing_driven/-congestion等,若有congestion,可以设置set_congestion_options来设置合理的值,设置好placement的一些参数后,可以进行place_opt了。

(7)cts的具体操作

cts可以通过GUI—>New Clock Tree Synthesis Window/New Interactive CTS Window查看时钟树的直观形状,可以设置clock_routing_rule来合理安排时钟树的线宽(NDR,Non-Default Rule)。设置OCV和bc_wc的工作条件。

(8)route的具体操作

需要先check_physical_design –for_routing检查布线的物理设计,以及check_routeability。Set_route_options可以设置route设置相关的选项,route_opt包括route clock nets,route signal nets,set_route_opt_strategy可以设置route相关的策略。分析route的结果可以使用verify_route和verify_drc(使用hercules),postroute delay calculation using Arnoldi algorithm。考虑si的route需要设置set_si_options。Spread_eco_cells/insert_spare_cells,place_freezen_silicon/route_eco

第四篇:GridCtrl使用小结

http://www.xiexiebang.com/

GridCtrl使用详解

CGridCtrl类主要是通过grid样式显示数据 在单文档中的使用方法

步骤一 初始化 在CView类的.h头文件中包含文件:

#include “Gridctrl.h” 并且手写加入如下的成员函数:

CGridCtrl * m_pGridCtrl;步骤二 构造与析构 构造函数中:

m_pGridCtrl = NULL;析构函数中:

if(m_pGridCtrl)

delete m_pGridCtrl;步骤三 如果需要打印功能的话添加同名打印函数代码 在CView类的OnBeginPrinting()函数中添加如下代码: if(m_pGridCtrl)

m_pGridCtrl->OnBeginPrinting(pDC,pInfo);//简单吧,这就是类的好处其它两个打印函数也一样的做法.步骤四 在OnInitaUpdate()函数中或者你自己添加的要显示Grid的消息函数中如下初始化: //创建非模式对话框 CDlg *dlg;dlg=new CDlg();dlg->Create(IDD_Dlg,this);

//初始化GridCtrl控件 if(m_pGridCtrl!=NULL){ deletem_pGridCtrl;m_pGridCtrl=NULL;} if(m_pGridCtrl == NULL){ // Create the Gridctrl object m_pGridCtrl = new CGridCtrl;if(!m_pGridCtrl)return 0;// Create the Gridctrl window CRectrect;GetClientRect(rect);m_pGridCtrl->Create(rect, this, 100);// fill it up with stuff m_pGridCtrl->SetEditable(false);m_pGridCtrl->SetTextBkColor(RGB(0xFF, 0xFF, 0xE0));//黄色背景 m_pGridCtrl->EnableDragAndDrop(false);try { m_pGridCtrl->SetRowCount(k);//设置行数为k行 m_pGridCtrl->SetColumnCount(4);//k列

m_pGridCtrl->SetFixedRowCount(1);//标题行为一行

http://www.xiexiebang.com/

m_pGridCtrl->SetFixedColumnCount(1);//同上 } catch(CMemoryException* e){ e->ReportError();e->Delete();return 0;} //填充列标题 int row=0;for(int col=0;col<4;col++){ GV_ITEM Item;Item.mask = GVIF_TEXT|GVIF_FORMAT;Item.row = row;Item.col = col;if(col==0){ Item.nFormat = DT_CENTER|DT_WORDBREAK;Item.strText.Format(_T(“【类别】”),col);} else if(col==1){ Item.nFormat = DT_LEFT|DT_WORDBREAK;Item.strText.Format(_T(“第一列”),col);} else if(col==2){ Item.nFormat = DT_LEFT|DT_WORDBREAK;Item.strText.Format(_T(“第二列”),col);} m_pGridCtrl->SetItem(&Item);} // fill rows/cols with text for(row = 1;row < k;row++)for(col = 0;col < h;col++){ GV_ITEM Item;Item.mask = GVIF_TEXT|GVIF_FORMAT;Item.row = row;Item.col = col;if(col < 1){ //行标题头

Item.nFormat = DT_CENTER|DT_VCENTER |DT_SINGLELINE|DT_END_ELLIPSIS |DT_NOPREFIX;Item.strText.Format(_T(“%d”),row);

http://www.xiexiebang.com/

} else if(col==1){ //第一列的值 Item.nFormat = DT_CENTER|DT_VCENTER |DT_SINGLELINE|DT_END_ELLIPSIS |DT_NOPREFIX;str=“aa”;Item.strText.Format(_T(“%s”),str);}else if(col==2){ //第二列第值 Item.nFormat = DT_CENTER|DT_VCENTER |DT_SINGLELINE|DT_END_ELLIPSIS |DT_NOPREFIX;CStringstr;str=“bb”;Item.strText.Format(_T(“%s”),str);} m_pGridCtrl->SetItem(&Item);} m_pGridCtrl->AutoSize();

//--------------设置行列距------------------for(int a=1;aSetRowHeight(a,21);//设置各行高 m_pGridCtrl->SetRowHeight(0,24);//设置0行高 m_pGridCtrl->SetColumnWidth(1,110);//设置2列宽 m_pGridCtrl->SetColumnWidth(2,160);//设置3列宽 m_pGridCtrl->SetColumnWidth(3,100);//设置4列宽 } 上例取自实际工程,稍有修改!部分注释: void SetVirtualMode(TRUE)//设为虚模式 BOOL SetRowCount(intnRows)//设置总的行数。BOOL SetFixedRowCount(intnFixedRows = 1)//设置固定的行数据 BOOL SetColumnCount(intnCols)//设置列数 BOOL SetFixedColumnCount(intnFixedCols = 1)//设置固定的列数

步骤五: 添加WM_SIZE消息,调整控件的界面占屏幕大小

if(m_pGridCtrl->GetSafeHWnd())

{

CRectrect;

GetClientRect(rect);

m_pGridCtrl->MoveWindow(rect);

}

在对话框中的使用方法 步骤一 创建数据显示表格对话框

在资源管理器中新创建一个对话框,假设为CDlgTestReportBox。从工具箱中加入Custom Control,就是人头像的那个,将其区域拉伸至要显示数据表格的大小,充满整个对话框。

在CDlgTestReportBox类的头文件中: #include “GridCtrl.h”

http://www.xiexiebang.com/

再定义成员变量: CGridCtrl* m_pGrid;添加OnShowWindow()消息处理函数如下:

voidCDlgTestReportBox::OnShowWindow(BOOL bShow, UINT nStatus){ CDialog::OnShowWindow(bShow, nStatus);// TODO: Add your message handler code here if(m_pGrid!=NULL){ deletem_pGrid;m_pGrid=NULL;} if(m_pGrid==NULL){ m_pGrid=new CGridCtrl;CRectrect;GetDlgItem(IDC_ReportAera)->GetWindowRect(rect);//得到显示区域 ScreenToClient(&rect);m_pGrid->Create(rect,this,100);m_pGrid->SetEditable(false);m_pGrid->SetTextBkColor(RGB(0xFF, 0xFF, 0xE0));//黄色背景 try { m_pGrid->SetRowCount(10);//初始为10行

m_pGrid->SetColumnCount(11);//初始化为11列 m_pGrid->SetFixedRowCount(1);//表头为一行 m_pGrid->SetFixedColumnCount(1);//表头为一列 } catch(CMemoryException* e){ e->ReportError();e->Delete();// return FALSE;} for(int row = 0;row GetRowCount();row++)for(int col = 0;col GetColumnCount();col++){ //设置表格显示属性 GV_ITEM Item;Item.mask = GVIF_TEXT|GVIF_FORMAT;Item.row = row;Item.col = col;if(row==0&&col==0)//第(0,0)格

http://www.xiexiebang.com/

{ Item.nFormat = DT_CENTER|DT_WORDBREAK;Item.szText.Format(_T(“报表显示”),col);} else if(row < 1)//设置0行表头显示 { Item.nFormat = DT_CENTER|DT_WORDBREAK;Item.szText.Format(_T(“ 项目%d”),col);} else if(col < 1)//设置0列表头显示 { if(rowGetRowCount()-4){ Item.nFormat = DT_CENTER|DT_VCENTER|DT_SINGLELINE|DT_END_ELLIPSIS;Item.szText.Format(_T(“第%d次”),row);} } else { Item.nFormat = DT_CENTER|DT_VCENTER|DT_SINGLELINE|DT_END_ELLIPSIS;Item.szText.Format(_T(“"),2);} m_pGrid->SetItem(&Item);} m_pGrid->Invalidate();} //--------------设置行列距------------------for(int a=0;aGetRowCount();a++)m_pGrid->SetRowHeight(a,16);//设置各行高 m_pGrid->SetColumnWidth(0,58);//设置0列宽 for(int b=1;bGetColumnCount();b++)m_pGrid->SetColumnWidth(b,59);//设置各列宽 }

步骤二 嵌入上面的对话框 显示数据

在你需要显示数据的对话框上的头文件中,假设为CDlgTest,加入 #include ”GridCtrl.h“ CDlgTestReportBox* m_pTestReportBox;将数据显示对话框放入你的对话框相应位置上,在CDlgTest::OnInitDialog()中:

if(!m_pTestReportBox){

m_pTestReportBox=new CDlgTestReportBox(this);} m_pTestReportBox->Create(IDD_DlgTestReportBox,this);

http://www.xiexiebang.com/

//定义区域变量 CRectrectDraw;GetDlgItem(IDC_AeraReport)->GetWindowRect(rectDraw);ScreenToClient(&rectDraw);//动态测试数据显示区域rectDraw //将对应的对话框放到指定区域 m_pTestReportBox->MoveWindow(rectDraw);m_pTestReportBox->ShowWindow(SW_SHOW);自定义填充数据的函数:CDlgTest::FillGrid()如下: CGridCtrl* pGrid=m_pTestReportBox->m_pGrid;for(int row = pGrid->GetRowCount()-1;row >= pGrid->GetRowCount()-3;row--){ for(int col = 1;col <= pGrid->GetColumnCount();col++){ GV_ITEM Item;Item.mask = GVIF_TEXT|GVIF_FORMAT;Item.row = row;Item.col = col;if(row==pGrid->GetRowCount()-3&&col>0)//平均值 { if(col==10){ Item.nFormat = DT_CENTER|DT_WORDBREAK;Item.szText.Format(_T(” %6.2f “),avjch);} else{ Item.nFormat = DT_CENTER|DT_WORDBREAK;Item.szText.Format(_T(” %6.2f “),av[col-1]);} } pGrid->SetItem(&Item);//提交数据 if(row==0||col==0){ COLORREF clr = RGB(0, 0, 0);pGrid->SetItemBkColour(row, col, clr);pGrid->SetItemFgColour(row, col, RGB(255,0,0));} }//循环结束

pGrid->Invalidate();} CGRIFCTRL原理:

DBGRID和一般的GRID的不同之处在于,一般的GRID并不适合显示大的数据量,如果一个表中有上万条记录都要插入到GRID中,这将是一个很慢的过程,并且在GRID中移动滚动条时,它的记录的滚动也是很慢。而DBGRID并不会真正把这些记录的数据全部插入到控件中,当DBGRID的滚动条滚动时,它会根据DBGRID的显示面积的大小和查询得到的总记录数计算出当前应该显示哪些行,然后插入

http://www.xiexiebang.com/

到表格中,这样一来,速度肯定快,而且没有数据量多少的限制。幸运的是,CGridCtrl类已经为我们提供了这种机制,它是采用虚模式实现的。使用这种方式,即使你向这个该控件插入一百万条数据,它并不会真的生成一百万行,而是随着你的滚动条的滚动,计算出在屏幕上要显示的行和列,然后会向你提供一个接口,通过这个接口,你可以在这儿设置你要显示的数据。下面给出使用CGridCtrl控件的虚模式的步骤: 步骤一 初始化

在视图的初始化函数里添加如下代码:

void SetVirtualMode(TRUE)

设为虚模式

BOOL SetRowCount(intnRows)

设置总的行数。

BOOL SetFixedRowCount(intnFixedRows = 1)

设置固定的行数据 BOOL SetColumnCount(intnCols)

设置列数 BOOL SetFixedColumnCount(intnFixedCols = 1)设置固定的列数 步骤二 响应消息 显示数据

我们假设CGridCtrl是放在单文档视图中,而且它关联的变量是m_GridCtrl,利用ClassWizard添加视图的OnNotify响应函数。这个响应函数的写法是固定的,类似下面的代码:

BOOL CGridCtrlTestView::OnNotify(WPARAM wParam, LPARAM lParam, LRESULT* pResult){ if(wParam ==(WPARAM)m_Grid.GetDlgCtrlID()){ *pResult = 1;GV_DISPINFO *pDispInfo =(GV_DISPINFO*)lParam;if(GVN_GETDISPINFO == pDispInfo->hdr.code){ //这是添加的函数,在这个函数里设置当前要显示的数据 SetGridItem(pDispInfo);return TRUE;} } returnCGridCtrlTestView::OnNotify(wParam, lParam, pResult);} 在上面的代码中,SetGridItem(pDispInfo)是添加的函数,在这个函数里我们设置当前要显示的数据。pDispInfo是一个GV_DISPINFO的结构体对象,它包含了每个单元格的信息,如行号,列号,有没有位图,背景色,前景色等。CGRIDCTRL会把当前要显示那个单元格行号,列号传递给我们,我们只要设置里面显示的数据就可以了。如下面是一个显示数据的例子。

voidCGridCtrlTestView::SetGridItem(GV_DISPINFO *pDispInfo){

pDispInfo->item.strText.Format(”row%d,col%d",pDispInfo->it

http://www.xiexiebang.com/

em.row, pDispInfo->item.col);}

第五篇:git使用小结

git使用小结

1.git-config 配置git,一般需要配置的是user.name,user.email,有时sendemail.smtpserver也要配置,比如,我使用msmtp:

git-config –global sendemail.smtpserver /usr/local/bin/msmtp 如果你仅仅是想给这一个项目配置,把–global选项去掉。查看配置的选项是–list。2.git-pull git-pull没必要带后面那长长的url(-_-b 我那么用了好多次,不过我用的是!git-pull)。如果你在给Linux内核这样的项目工作,记得git-pull之前检查是不是在master分支。3.git-format-patch 如果发送多于一个补丁,最好用[PATCH n/m]的形式,加上-n。加signed-off-by那行是-s。指定为几次commit生成补丁,直接加数字,比如,$ git-format-patch-3 检查补丁是–check,最好加上这个。4.git-send-email 如果一次提交补丁比较多,最好用–no-chain-reply-to,因为如果不用的话,在thread嵌套会太深,不利于别人阅读。这个也可以通过选项sendemail.chainreplyto来控制。–signed-off-by-cc,要加上,可以省去手工处理的麻烦。–compose用来编辑[PATCH 0/m],这个一般是对整个patchset的描述。–smtp-server,如果你不想用git-config指定的话,用它也行。–cc和–to就不用说了。5.git-commit 在git-commit之前最好git-add。git-commit几个常用的选项有:-s 会增加Signed-off-by行,-e编辑commit message,-a表示all,-m是指定commit信息。同样,删除文件是先git-rm。查看commit列表用git-rev-list,查看某个commit用git-show,查看commit的日志用git-log,-p是以补丁的形式查看。6.其它 git-diff也可以比较不同版本之间的差异,某个版本的某个文件的差异,如: $ git-diff v2.6.22 $ git diff v2.6.20 init/main.c $ git-diff v2.6.23 v2.6.24-rc1 init/main.c git-whatchanged也差不多: $ git-whatchanged-p init/main.c 7.错误提交了commit怎么办? a)git-revert 这个本身就会产生一个commit,如果用得多了会让你的log看起来不那么干净。;-)b)git-reset 用这个要当心,它会把那个commit之后的commit全部删除。一个好的办法是:先建立一个临时的分支,然后再git-reset,再git-rebase,最后再删除临时的分支。详细可以看这里。
