| + | ===== Environment setup ===== | ||
| + | |||
| + | Create a working area, | ||
| + | |||
| + | <code> | ||
| + | cd ~/scratch | ||
| + | mkdir tutorials | ||
| + | </code> | ||
| + | |||
| + | |||
| + | Move into your working area and create a basic ''cds.lib'' file with your | ||
| + | preferred text editor and put the following lines | ||
| + | |||
| + | <code> | ||
| + | # standard Cadence libraries | ||
| + | INCLUDE $ID_DIR/../cds.lib | ||
| + | </code> | ||
| + | |||
| + | |||
| + | All the proposed tutorials will be carried out with a Cadence IC 6.1.5 | ||
| + | technology-independent environment, as described in | ||
| + | __[[vlsi:computing_cdsterm#start_a_vanilla_environment|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: | ||
| + | |||
| + | <code> | ||
| + | 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" & | ||
| + | </code> | ||
| + | |||
| + | |||
| + | To save time you can put these instructions into an executable ''setup.csh'' | ||
| + | csh script, | ||
| + | |||
| + | <code> | ||
| + | #!/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" & | ||
| + | </code> | ||
| + | |||
| + | |||
| + | <code> | ||
| + | chmod +x setup.csh | ||
| + | ./setup.csh | ||
| + | </code> | ||
