Setup for 130nm IBM PDK
How to Setup the 130nm IBM PDK
This tutorial is designed to help students set up a cadence working directory that is linked to the 130nm IBM PDK.
IMPORTANT Before any student will be granted access to the IBM PDK, they must sign the MOSIS Individual NDA for University Account Students and Staff which can downloaded from: https://www.mosis.com/files/mosis_forms/academic_nda_non-liaison.pdf
The signed NDA should be submitted, along with a valid ISU NetID to Dr. Nathan Neihart.
In order to use the IBM PDK you will need to create a directory that will house all of the necessary configuration files. This is the directory from which you will launch Virtuoso and will heretofore be referred to as the IBM working directory. To facilitate the creation of your IBM working directory, a template directory has been created.
- Fist copy the
DM_template61directory and place it wherever you store your cadence directories (the copied directory can be named anything that you like). You can do this by entering the following command into a terminal:
cp -r /remote/cadencelib/nda/ibm8rfcmos/DM_template61 ~/<CADENCE_DIR>/cmrf8sf
<CADENCE_DIR></big>is the name of your directory where you store all of your cadence files and
cmrf8sfis what I chose to call my IBM working directory.
- There are several environment variables that need to be assigned for the PDK to run correctly. Add the following lines to your
export SPECTRE_DEFAULTS=-E export CDS_LOAD_ENV=CWDElseHome export QRC_ENABLE_EXTRACTION="t" export QRC_HOME="/usr/local/cadence/EXT101"
- Finally, modify your
~/.softwarefile to include the following lines:
IC CALIBRE2009 ASSURA MMSIM EXT
- Note that you may have additional entries, but add them after the entries listed below.
- The setup is now complete. To use the PDK simply launch virtuoso from your newly created IBM working directory.
