LVS fail

peter450

 I'm using bicmos8hp technology for a design. After completing DRC and running LVS I'm facing a problem

 *****  nvn fork terminated abnormally  *****



*WARNING* nvn exit with bad status
*WARNING* Status 256
*WARNING* Assura execution terminated.

I think the settings for LVS are not proper.  I used correct extractrules,binding rules, compare rules,rsf inclde files. 

 Can anyone help me ?

  •  I'm using Assura 4.1 and spectre 7.2. Some of the warnings I found in log file are

     WARNING Undefined layer in dfII.
        Layer name 'BI' doesn't exist, treating as an empty layer.
        bi = layer("BI" type("drawing"))

    WARNING LVS Run detected.
    Non-legacy mode has been disabled for this LVS run

    *WARNING* The terminals are not in parentheses. This is old syntax and will
             be interpreted as a device with fixed terminal number.
             The rule will be converted internally to new syntax:
             resDevice("kqres" ("D" "S" nil))
