| 3.1 Step by step:L-edit

Prerequisite steps

- Make a new cell
- Rename it to 'Resistor assembly'

Instantiate two 'Resistor 8k' cells

- Instantiate a 'Resistor 8k' via the menu 'Cell- >Instance'
- Pick the 'Resistor 8k' cell
- Press OK
- Click anywhere in the window to position the cell.
- Position the resistor such that the centre of the left SUCON square is at the origin of the cell
- On the left side of your screen you should have a feature with three columns. Each column correspond to a button on your mouse and tells you what happens if you click/click and hold+++
- Use the centre button to move the resistor into position
- Tip: watch the status line at the bottom left corner of the application window.
- Instantiate a second resistor.

Your design should now look like this |

Rotate one cell 90 degrees

- Select the second resistor. When selected you will see it outlined.
- Rotate the second resistor via the menu 'Draw- >Rotate->90 degrees'

Align the SUCON regions of the cells to connect the electrically

- Select the second resistor.
- Use the centre button to move the resistor such that the SUCON areas of one end of the resistors align.

Your design should now look like this |

Browse the hierarchy

- To see the hierarchy you press the menu 'View- >Design Navigator'
- Press the '+' sign
- We can now see that the file contains two cells:
- A 'Resistor 8k' cell
- A 'Resistor assembly' cell with 2 instantiations of 'Resistor 8k'

Extend the SUCON squares in 'Resistor 8k' by 2 microns in the length of the resistor. Remember to change the size of NOBOA and NOSUR accordingly |  |
Your design should now look like this |
Undo the changes to 'Resistor 8k' |
