| 1) | The upper left end contact pad configuration shows a resistor line of width W terminated in a 3W x 3W resistor end pad. The W x W contact via is centered in the end pad. The contribution of 0.65 square is for everything left of the joint between the 3W and W sections of resistor. |
| 2) | The upper right end contact pad configuration shows a resistor line of width W terminated with a (W/2) x (W/2) contact via dropped onto the line. The contact via is (W/4) away from the edges of the resistor on three sides. The contribution of 0.14 square is for everything left of the right edge of the contact via. |
| 3) | The lower left end contact pad configuration shows a resistor line of width W terminated with a 2W x 2W resistor end pad. The W x W contact via is centered in the end pad. The contribution of 0.35 square is for everything left of the joint between the 2W and W sections of resistor. |
| 4) | The lower right figure shows a square corner, which contributes 0.56 square. |
