    Pin layers not coming after running stream in layout Reply

    Hi guys,

                I have created layout with LVS clean. And then I have translated the layout into .gds format through "streamOut". Now I streamIn it to a library. But all pins are missing in layout . 

    Thank you,

    sarvani.

    Hi Sarvani

    You can preserve DFII pins as follows:
    a. In stream out form, set a suitable "Pin Attribute Number" before streaming out
    b. In stream in form, set the same pin attribute number.

    Best regards

     Hi quek,

                Thank you for your suggition. What may be the issue in this? Some times I need to run LVS for GDS2 format. Then again I am getting this pin issue. And by the way thank you for your precious suggitions in previous posts.

    Thank you,

     After steamIn, property of pin is converted from "RECTANGLE PIN" to "RECTANGLE". By setting same pin attribute number while streamOut and streamIn is works good. But while running LVS for GDS file then pins doesnot recognizing .

    thankyou,

    Sarvani

    Hi Sarvani

    GDS format does not know what is "DFII pin" so it is not possible to preserve the pins in gds format. You can stream out the pin as "geometry+text" so that Assura's textToPin cmd can read in the labels and use them as pins.

    Best regards
