    Problem on Importing GDSII file into Virtuoso Reply

    I'm using Virtuoso 6.1.4-64b on University's desktop running CentOS. 

    I have a GDSII file generated from SoC Encounter and I'm using the Nangate 45nm Opencell library. Before tried to import GDSII into Virtuoso, I've modified the cds.lib file and added a line to define the Nangate library directory.


    What I did, basically, was I followed the instructions on http://users.ece.gatech.edu/limsk/course/ece6133/lab/virtuoso.html to import GDSII into Virtuoso. What I get after I hit "Translate" is a pop-up window of "Stream in translation complete", saying

     "Info: Cellvie Rev Num:99,  Tech Rev Num:59"

    "Do you wish to view the log file?"

     "Yes       No"

     And I click yes to see the log file, and there's nothing in it execept some headers for dates, user name, and one line of   "Info: Cellvie Rev Num:99,  Tech Rev Num:59". Nothing else.

    Then I went to CIW-Tools-Library Manager, and select nangate in "Library", here is the PROBLEM----I cannot see my gdsII file's name in the "cell", the "cell" column only has all the nangate cells such as AND2_X1, AND2_X2, AND2_X4 and so on.

    I don't know where I made a mistake in the process. Could you guys help me figure out what step could possibly be wrong and I'll check that? I really appreciate any help. Thank you!


    PS: I have doubts on what to fill out in the "Show Options" under Virtuoso XStream In window. I left it blank.
