| + | For 45nm CMOS, select the **gpdk045** library when asked for the name of the Attach To Technology Library. | ||
| + | |||
| + | When using model files directly (such as 90nm CMOS in this course), select the default **cdsDefTechLib** library when prompted to Attach To Technology Library. | ||

| + | 1) Create a "cds.lib" file. Using any text editor the following entry should be put in the cds.lib file: | ||
| + | |||
| + | <code> | ||

| + | |||
| + | <code> | ||
| + | ln -s /home/vsaxena/pdk/gpdk045_v_5_0/models | ||
