|
Creating a new Cell Library |
Element, Cells, File, New |
|
Step 1-Specify seed file |
Seed2d.cel for 2d cells; seed3d.cel for 3d cells |
|
Step 2-Specify name and directory of cell library |
|
|
Step 3-Click OK button |
Closes dialog box and creates new cell library |

Creating New Cells |
|
|
To consider before starting |
Working units, cell rotation, cell origin |
|
Step 1-Draw the elements |
Seed2d.cel for 2d cells; seed3d.cel for 3d cells |
|
Step 2-Group elements by fence or element selection |
