How to change or set connection information for a MOS in layout XL?

iDave

Hi All,

As we all know,  we can create a dummy MOS in layout XL by right-mouse-button -> create dummy (select a Net name), and the skill command is leHiMakeDummy. 

Through this way, the dummy MOS will have connection info, we can see the term name in MOS”s gate/source/drain.

Is there a similar command to do the same things but no need any interactive operation? Because I want to create some dummy mos in a skill procedure, and need the term name of the dummy MOS.

Or is there any way  to change or specify the term name for a MOS?

Regards,

Dave

  • Hi Dave,

    There's no function called leHiMakeDummy - in fact there's no public function to create the dummies in this way (either with the UI or without). However, there are public functions to do so as part of a modgen - do a search in cdsFinder for "Dummy" to see the functions. You should contact customer support if you need this enhancement.

    Regards,

    Andrew.

    Hi Andrew,

    The function is called _lxMakeDummy(“netName”).

    And In layout XL, you can select a mos -> click right-mouse-button -> click Create Dummy With Net -> click a net name -> point reference point in layout window -> point location in layout window.  

    You can test this as I said above. 

    My virtuoso version is IC617 ISR15

    Hi Dave,

    I know how to do this, thanks. As I said though, there's no public function (the function you mention is the one triggered by the menu, which I was already aware of, and it's private and not intended for use in SKILL code). You'd need to contact customer support as I mentioned earlier if you want an enhancement for a procedural interface to do what you want (i.e. without needing interactive input).

    Regards,

    Andrew.
