Completely technology-independent tutorials, importing simple SPICE transistor models that you can find on Web and in textbooks

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

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.
