一、前言
在此前的文章介绍了Cadence IC617的安装方法、流程以及.bashrc启动环境文件的配置方法。
[post cid="3" cover="" size=""/]
直接复制以及写好的.bashrc文件修改其中的部分路径与设置实现Cadence的environment setting，这种方法比较通用简单，适合小白快速配置，但是直接复制过来的.bashrc中有过多的杂项与冗余项，会影响Candence的启动速度，后期使用也有可能出现问题导致软件无法启动。
因此考虑重写environment file，Cadence支持加载.bashrc与.cshrc两种格式的environment setting，考虑到Linux常用终端均为bash环境，为了区分Linux system environment与Cadence Project environment setting，采用编写.cshrc配置Cadence启动environment。
二、.bashrc分析
先贴上我之前使用的.bashrc文件
[collapse status="false" title=".bashrc"]
#--------------------------------------------------------------------------------------------------
# User's Guide
# Copy this .bashrc environment setting file to the working (design project) directory, e.g.
# /home/johndoe/project1, /home/johndoe/project2, ...., etc.
# On terminal, cd to the working directory and then source the .bashrc file by typing the
# following at the shell prompt $:
# . .bashrc
# Note: a space is required between "." and ".bashrc" in the above command.
# Now all the environment variables in .bashrc file have been loaded into the current shell
# terminal and commands can be issued at the shell prompt $ to launch various Cadence
# tools, for instance, "virtuoso &" (without the quotes). Some frequently used commands are
# listed in this file together with corresponding environment settings.
# You may finish the Cadence session at any time by closing the running Cadence tool. To
# start up another Cadence session, just issue another Cadence command at the shell
# prompt $, e.g. "innovus &" (without the quotes), etc. To exit the entire Cadence
# environment, close the terminal. By closing the terminal, all loaded Cadence and Calibre
# environment variables are terminated since all of these variables are loaded and
# contained in the terminated shell terminal. The benefit of sourcing .bashrc to a local shell
# terminal instead of setting them in the $HOME/.bashrc is that all of the loaded Cadence &
# Calibre environment variables don't globally affect system environment settings and
# therefore you can run other programs on the system normally and won't disturb the
# Cadence session or vice versa.
# If you're setting up a multiuser server, create a client copy of this .bashrc file and make
# necessary changes accordingly, e.g. point CDS_LIC_FILE to the server's license directory
# as port@hostname. Instruct users to download it to the working directory on the client
# machine and source the client copy before starting up any Cadence tool.
#--------------------------------------------------------------------------------------------------
#+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
# For proper distributed processing execution using Cadence PVS software, it requires
# that the following is set as the first line in .bashrc
# Note: the space between the ! and $prompt is required!
#+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
if (! $prompt); then
exit

在.bashrc中关于CADHOME为Cadence 安装目录，CDS为IC617安装目录，CDS_LIC_FILE为Cadence License文件目录，MMSIMHOME为MMSIM仿真器安装目录，CALIBRE_HOME为验证器Calibre安装目录。
文件中还涉及到QRC、K2、ASSURA、Universal Verification Methodology (UVM) 等诸多插件的配置，没有安装对应插件需要注释掉所有相关配置，若有使用则需要正确配置路径。
三、配置.cshrc
为了配置文件更加简洁明了，方便后期维护与环境的升级，采用csh环境编写.cshrc配置Cadence启动。

#endif
setenv MGC_CALIBRE_REALTIME_VIRTUOSO_SAVE_MESSENGER_CELL 1
setenv MGC_CALIBRE_SAVE_ALL_RUNSET_VALUES 1
[/collapse]
上述.cshrc整体更加简洁，所用到的IC617、Calibre2015、MMSIM151都有对应配置方便后期维护，如果还需要其他验证器例如ASSURA可以参考.bashrc文件进行配置。
