How to modify Pcell Transistor's metal/contacts?

Aramsh

 Hi All,

Can you please help to do the following in IC6.1 layout:

1. Change the width of Metal over the transistor S/D. Assuming technology library is untouchable

2.  Move contacts of Pcell transistor

3. Change number of contacts in Pcell transistor S/D

4. BTW, how to make ESC key working when want to cancel popup windows?

 Thanks!

Aram

  • Unless the pcell has parameters to support moving the contacts or changing the number of contacts (sometimes they have stretch handles on them, which you can enable via the Options->Display form), then you'll need to flatten the transistor and modify it.

    What kind of popup windows are you talking about? Options forms for enter functions already get cancelled when hitting Escape.

    Regards,

    Andrew.

  •  Hi Andrew,

    For example if I call parameter window (using q) and then I can't get rid of it using Esc key

     

    Thanks,

  • If it's schematic, you could probably define the bindkey for Esc to be hiFormCancel(hiGetCurrentForm()) . If it's layout though, the edit properties form is not an "hi" form, and so this won't work.

    Alternatively use the property assistant (Window->Assistants->Property Editor) and then you can use F11 to hide it or show it.

  •  Hi Andrew,

    Unfortunately it's layout window, but it doesn't work for any popup window, wire editor, via editor, etc.

    Can I make hiFormCancel(hiGetCurrentForm())anyway?

     BTW, I see the following in my bindkey file

     

      bk("Layout" "<Key>Escape EF"        "cancelEnterFun()")

    What does that mean?

    Thanks,

    Aram

  • Your message got a bit scrambled.

    The bindkey you have there is an "Enter Function" bindkey (hence the EF at the end). This means that it is picked up whenever an enter function is in force - for example, create wire, create via, and so on. Edit Properties is NOT an enter function, and so that needs do be done differently - it would have been:

    bk("Layout" "<Key>Escape" "hiFormCancel(hiGetCurrentForm())")

    but as I said, the layout edit properties form is not a SKILL form, and so is not cancellable.

    You can have both the standard bindkey and the EF bindkey defined at once - they operate in different phases.

    Regards,

    Andrew. 

  •  Hi Andrew,

    I got your point. Thanks for the answers!
