【VIM】以VIM做SV工具

VI(M)的使用經驗起自文字終端機的時代，包括最早的行編輯器，到全螢幕編輯。晚近則是ECO時手動修改NETLIST的經驗，一 般的EDITOR碰到體積龐大的NETLIST(印象好像是幾百MB，或是GB等級)，會轉不過來，或轉不動，但是VI卻依然輕鬆自如。VIM號稱是Linux的標準瑞士刀，從小型的EMBEDDED裝置到各式PC(包括MACOS)，伺服器，都可見其蹤影。桌面環境，包括Windows，也有GVIM(視窗版)可用。可以說，以此一招，可以闖江湖矣!

最近的經驗是DDR4 Behavior Model的開發，環境則是 Red Hat Linux 桌面，這次算是比較長時間持續地使用，所以把VIM的一些經驗整理存參。
