===== Introduction =====

le celle si istanziano, non si disegnano a mano!



===== Substrate contacts =====

anche questo e' technology-independent, basta fare un place guard ring oppure place via tra M1 e substrato
con molteplicita' varia

**Layout Editor L/XL => Create => Via** shortcut <o>

===== NMOS layout =====

technology-independent nel senso che un NMOS e' un NMOS! 2 pozzetti e un gate di polisilicio non sono un mistero!

da non dimenticare pero' anche il contatto di substrato!

Fatto bene:  //[[http://cmosedu.com/videos/cadence/tutorial2/cadence_tutorial_2.htm]]//

**Library Manager => File => New => Cell view**

Choose the layout view 


**Layout Editor L => Create => Instance** and select the layout view of the standard NMOS device provided by the technology you are using.

Verificare con **<shift + f>** che vedo i layers oppure solo un abstract con un red-box!

**Layout Editor L => Edit => Hierarchy => Flatten**


===== PMOS layout =====

Fatto bene:  //[[http://cmosedu.com/videos/cadence/tutorial2/cadence_tutorial_2.htm]]//

**Layout Editor L => Create => Instance** and select the layout view of the 
standard PMOS device provided by the technology you are using

**Layout Editor L => Edit => Hierarchy => Flatten**
