load via options into cadence session

psill00

What is the variable to define via selection/type for vias

I want to be able to load via cut type in the via option when I use the leHiCreateVia() function

I want to select/load to the Via Option menu on which via I want to use

Cadence version IC23.1.64b.ISR7.27

    I tried what the article has and it does put the via as defined, but I want the auto feature when I used the leHiCreateVia

    Not sure how to explain ( I dont want to upset the IP watchers )

    le0ViaForm->viaMode->value="Auto"
    _viaOpenCreateViaOptionFormCB()

    I dont want to use a via/contact
    viaOptionsForm->viaRestrictLayer22->value= nil 

    I want to use a specific via/contact from the via list ( Example of a valid contact list '("contact" contactV" contactH") )
    viaOptionsForm->viaOptionDefCutClassCyclic21->value="contact"


    Is there a way I can set the contact/via values when I start cadence?

    I tried the script in the article and it works as described, but I want the use the Auto feature in leHiCreateVia

    Not sure how to explain clear ( I dont want to upset the IP watchers )

    leHiCreateVia()
    le0ViaForm->viaMode->value="Auto"
    _viaOpenCreateViaOptionFormCB()

    I dont want to use a contact/via from the list
    viaOptionsForm->viaRestrictLayer22->value= nil

    I want to use a specific contact/via from the list ( Example of symbolic list '("contact" contactV" "contactH") )
    viaOptionsForm->viaOptionDefCutClassCyclic21->value="contact"

    Is there a way I can set this type of values in a file or variable when I start up cadence?

    I don't follow: "Auto" will select the correct via for the overlapping layers. You cannot define the via in this mode.

    If there are variants you wish to restrict then you probably need to look at the Constraint Group or Via Configuration options.
