短url的开源源代码
短url的好处就不用说了,
在邮件中不会折行,
……
短url的老大是http://tinyurl.com/,但是如果你想自己做一个缩短网址的网站,其实也很简单。
去http://lilurl.sourceforge.net/下载一个缩短网址的源代码,自己安装一下。
我自己也写了做了一个缩短网址,实现短url的网站,
网站连接如下: http://u9d.cn/ 意思为 “U就短”

Physical Design Rule
What’s Physical Design Rule
2. Guidelines for constructing process masks
3. Unit dimension: minimum line width
absolute dimensions: micron rules
5. A complete set includes
intra-layer: relations between objects in the same layer
inter-layer: relations between objects on different layers
ASIC Design Implementation Flow In Brief
- design setup;
- floorplan;
- placement;
- Clock Tree synthesis (CTS);
- routing;
- chip finishing( insert diode, insert filler, insert metal filler, add redundant via …);
- signoff flow ( StarRCXT, PT, DRC, LVS).
ASIC Design Flow In Brief
- chip specification;
- front end modeling, use C, C++ or System C/system verilog to do the modeling and simulation;
- design implementation in front end, verilgo or VHDL ;
- simulation;
- FPGA verification(optional);
- Synthesis, Design compiler , RTL to gate level netlist;
- Physical implementation.

Mapping File: Database Layer <==> Process Layer
Maps File:
Map database layers to process layers conducting_layers, via_layers, marker_layers, remove_layers.
Layer Information:
Resistance information is optional: RPSQ (for conductors) or RPV (for vias) overrides process file, if specified

长音与旋律循环换气 zz
此种循环换气是所有循环换气的基础和前提,不掌握这种换气法,其它两种循环换气就无法学会。

Interconnect Technology File (ITF)
What’s ITF:
ITF stands for Interconnect Technology File.
It contains a description of the process cross-section and connectivity section.
It describes the thicknesses and physical attributes of the conductor and dielectric layers.
It used to extract RC value for the chip.
It can be used to generate TLU TLUPlus files.
ITF file example http://gudonghua.googlepages.com/itf-file-example.itf.txt

羽毛球点滴:发球和反手
08年的主要运动形式为打毛球,第一次背上羽毛球拍的时候,有一种背上剑,行走江湖的感觉。
想象做一名运动员也挺好的,有一技之长,走遍江湖。
还记得在公司第一次比赛的时候,球拍也不知道怎么握(其实现在握法也未必正确,哈哈),现在也算会打球了吧。
……
……
昨天对两样技术又有了新的认识:
发球
发球时手臂和球拍应该不是再同一直线上的。
反手
