Introduction
Completely technology-independent tutorials, importing simple SPICE transistor models that you can find on Web and in textbooks
Environment setup
Create a working area,
cd ~/scratch mkdir tutorials
Move into your working area and create a basic cds.lib file with your
preferred text editor and put the following lines
# standard Cadence libraries INCLUDE $ID_DIR/../cds.lib
All the proposed tutorials will be carried out with a Cadence IC 6.1.5 technology-independent environment, as described in Start a vanilla environment.
Move into your working directory ~/scratch/tutorials and source by hand the
/usr/local/config/cds_config/CdsIC_615.rc Cadence IC configuration script:
setenv IC_DIR /usr/cadence/IC_6.1.5 source /usr/local/config/cds_config/CdsIC_615.rc xterm <code> Put a ''setenv MANPATH "" '' in your '.cshrc'' file, then <code> xterm -T "Cadence tututorial" &
To save time you can put these instructions into an executable setup.csh
csh script,
#!/usr/bin/csh setenv IC_DIR /usr/cadence/IC_6.1.5 setenv MANPATH "" source /usr/local/config/cds_config/CdsIC_615.rc xterm -T "Cadence IC 6.1.5 vanilla environment" &
chmod +x setup.csh ./setup.csh
Basic NMOS and PMOS characteristics
Step-by-step tutorial
this is a PDK-independent tutorial ( using a standard transistor-model! )
You can access the tutorial here. This tutorial has been prepared by Luca Pacher.
