标题
scs文件选择错误或者是指定的路径软件没有权限访问
谢谢！我看看！
看看！了
scs文件选择错误或者是指定的路径软件没有权限访问
我是用root用户操作的，如报错所说，没有找到/root/cmos10lpe/../models/Spectre/design.scs，然后我去这个地址找了，确实不存在design.scs，而不是访问权限问题。同时，这个pdk的安装包里确实有design.scs。
我想原因应该是root用户在调用pdk中的design.scs时没有成功吧。能解决吗?
你在input.scs里把input.scs的路径写对，报错信息已经很清楚了
另外并不是root账户就没有权限问题，虽然root可以更改权限
谢谢！我根本都没去修改xxx.scs的路径，所以报错了。现在正常了。小白初学，闹笑话了。
你好，我也正在使用IBM PDK， 可以请教一下吗?急
我是装好了这个IBM的pdk，初步仿真没有问题，你遇到问题了吗?
我是按照PDK 里面有个README.KIT.INSTALL安装的。他里面的步骤是这样的：Example:
1) Change directory to a temporary installation directory.
2) Extract the tar archive:tar -xvf <archive>(i.e. kit tar file name)
All files will be located in your current directory.
3) Execute "kit_install"
The script will:
- prompt for your destination directory <install_path>
- confirm your distribution file directory
- list the available packages that were included in the shipment
- prompt for which package(s) you want to install
- ask if the "rel" link should be set up for release number
The "rel" link is a symbolic link to the current release number.
This is useful for PATH statements, but it is not required.
- ask for final confirmation and then install the packages in <install_path>
所以，执行kit_install之后，我把cds.lib,.cdsinit,display.drf,assur_tech.lib都放到了work directory下面。然后再这个folder下面运行virtuoso&.
1.开始cadence IC615之后，我首先看到了三个warning:
*WARNING* (DEBASE-102068): No user triggers registered for viewType schematicSymbol.
*WARNING* (DEBASE-102068): No user triggers registered for viewType maskLayout.
*WARNING* (DEBASE-102068): No user triggers registered for viewType maskLayoutXL.
以下是我的library:
然后我再CIW里面点击IBM_PDK，create 了一个新的lib: tutorial. 选择M5 number of levels of metal. (这个地方我不知道选择其他的会有什么问题。180nm不是只有6层metal吗?为什么会有其他的选择?)
然后新建了一个cellview: inverter.
我添加的model 是NFET 和PFET。连完线，居然左下角有个vdd！和sub！。 这个怎么处理。我是第一次用IBM的PDK，我知道这两个是PMOS 和NMOS的body.但是我不知道应该怎么处理. 而且在我打开schematic的时候，有个warning：
*WARNING* (icLic-3) Could not get license Virtuoso_Schematic_Editor_L
*WARNING* (icLic-21) License Virtuoso_Schematic_Editor_L ("95100") is not available to run Schematics-L.
Trying to check out the license Virtuoso_Schematic_Editor_XL ("95115") instead.
这个有什么影响吗?是因为我的IC615 没有L license吗?那用这个XL 有影响吗?
打开ADE之后，在design variable里面出现了两个变量，可是我都没有设置，怎么会有呢
对于spectre的model libraries，我不太清楚选择哪些才能保证运行，我尝试了加入NFET,PFET和allmodels.scs，可是无法运行。
我用的是bash shell. 以下是我的.bashrc
# .bashrc
#！/bin/bash
# Source global definitions
if [ -f /etc/bashrc ]; then
. /etc/bashrc
fi
# User specific aliases and functions
export SPECTRE_DEFAULTS=-E
export CDS_Netlisting_Mode=Analog
export AMIS_DFII_DIR=/state/partition1/apps/cadence/IC615
说的有点多，可的确是很着急，都整了几个星期了，可是就是不清楚这样已经算是成功安装了PDK吗?可第一个简单的仿真都没弄出来。至少schematic建好，layout弄好，前仿后仿都没问题，那样才算OK了吧。
实在是急的很，特此请教一下。希望你能尽可能说多一点。如果可以，咱们可以QQ交流吗?或者email: cmosres@gmail.com
多谢。多谢
