下載、安裝、設定 Cadence Virtuoso EDA 工具
下載及驗證：
Cadence Virtuoso EDA 工具是業界佔有率相當高的 EDA 工具，主要功能在於繪製電路圖 (Schematic Entry)、符號圖 (Symbol)、佈局圖 (Layout)。除此之外，Cadence Virtuoso 亦可以直接呼叫外部工具來進行 Spice Simulation 以及 DRC/LVS驗證。
要安裝 Cadence Virtuoso EDA 工具，首先要下載 CIC 所提供的壓縮檔，以目前 (2020/03/12) 而言，其最新的版本是 IC_06.18.040，總共有五個壓縮檔要下載，如底下所示：
IC_06.18.040_linux_1of5.tgz
IC_06.18.040_linux_2of5.tgz
IC_06.18.040_linux_3of5.tgz
IC_06.18.040_linux_4of5.tgz
IC_06.18.040_linux_5of5.tgz
下載完畢後，請執行 gzip -t xxx.tgz 來測試所下載之壓縮檔是否有誤，如果沒有任何錯誤訊息的話，代表此壓縮檔格式正確，接下來可以進行安裝。
================================================================================
解壓縮及安裝：
建立安裝目錄
# mkdir -p /opt/EDA/cadence
解開壓縮檔
# tar xfva IC_06.18.040_linux_1of5.tgz -C /opt/EDA/cadence
# tar xfva IC_06.18.040_linux_2of5.tgz -C /opt/EDA/cadence
# tar xfva IC_06.18.040_linux_3of5.tgz -C /opt/EDA/cadence
# tar xfva IC_06.18.040_linux_4of5.tgz -C /opt/EDA/cadence
# tar xfva IC_06.18.040_linux_5of5.tgz -C /opt/EDA/cadence
解開之後，會出現
/opt/EDA/cadence/IC 目錄，在此目錄下即是已解開之 Virtuso EDA 工具。
================================================================================
設定 Virtuoso 環境
1. 要設定 Virtuoso，請看原廠設定手冊，其位置在
/opt/EDA/cadence/IC/cur/doc
目錄，我們要看有關 installation 或 setup 或 administrator's guide 之類的文件。以此例來說，在 doc 目錄下有一個名為 install 的子目錄，此目錄存放 Cadence Installation Guide，這是原廠的安裝手冊，任何設定上的問題，以此檔內敘述為主。
2. 設定 Virtuoso 執行路徑
由於我們的 PATH 變數還沒有設定 Virtuoso 的執行環境，如果執行
$ virtuoso
的話，會出現底下錯誤訊息：
bash: virtuoso: command not found
這是由於 virtuoso 目前沒有在 ~/.bashrc 的 PATH 變數中設定，
因此在 ~/.bashrc 中要加上底下設定：
Virtuoso="/opt/EDA/cadence/IC/cur/tools/bin"
icfb="/opt/EDA/cadence/IC/cur/tools/dfII/bin"
export PATH=$PATH:$Virtuoso:$icfb
####ENV for IC60 #####
CDS_LIC_FILE=5280@lsncku
CDS_INST_DIR=/opt/EDA/cadence/IC/cur
CDS_ROOT=/opt/EDA/cadence/IC/cur
CDS_HOME=/opt/EDA/cadence/IC/cur
CDS_Netlisting_Mode=Analog
CDSDIR=$CDS_INST_DIR/tools
#XKEYSYMDB=$CDS_INST_DIR/share/cdssetup/tdmX11/XKeysymDB
XNLSPATH=$CDS_INST_DIR/share/cdssetup/tdmX11/nls
CDS_AUTO_64BIT=ALL
OA_HOME=/opt/EDA/cadence/IC/cur/oa
export LM_LICENSE_FILE=5280@lsncku:1717@lsncku:27000@lsncku:26585@lsncku
設定完畢後，重新打開新的終端機視窗，在此視窗中執行
$ virtuoso
bash: /opt/EDA/cadence/IC/cur/tools/dfII/bin/virtuoso: /bin/ksh: bad interpreter: No such file or directory
上述的錯誤訊息是 virtuoso 找不到 ksh 這個 shell，請安裝 ksh 這個套件，再執行
