mingfatty

Hi there,

 As above, i could not see any nets info of my layout when i try to stream in my gds2 file (from encounter) to virtuoso. please kindly advise on what should i do to preserve the net information. 

Thanks in advance.

  •  Hi,

    gds2 is not a format to store net information.

    You can probably store the net connectivity as porperty on shapes but not sure that woudl really help.

    As you are using version on OA why not saving to OA and open it inVirtuoso ?

    Regards,

  •  Hi Alex,

     Thanks for the reply, i am actually tried to save my gds in oa format, but it keep showing the errors as below,

     "Could not find leaf cell SL_INV1X1"

     "ERROR: (SOCOAX-1049): Failed to create logical instance"

    "Can not create OA row ROW_0."

     May i know is there any standard flow of doing this! Many thanks in advance. 

     

    Regards,

  • Hello,

    When saving to OA from Encounter:

    1. You need to make sure you have the cell  SL_INV1X1 exists on OA and you have specified the library in the OA reference library on the Design Import form.
    2. In order to create row in your design you need to make sure you have to define the corresponding site in your techfile

    The easy way is first to create a new library in Virtuoso which 'reference' the technology library then importing the technology LEF inside this library in order to create the needed technology information and potentially the macro and std cells instances.

    regards,
    Alex

  • Hi Alex, I think i have get the way of how to save it using OA by using the parameter "ui_oa_reflib" in my configuration file, Thanks so much for the assist. Wishing you a good day! MF

  •  Hi MF,

     You are correct.

     You are welcome,
