How to use standard cells in Virtuoso

Hi,

I've a standard cell library from a vendor. 

I want to know if there is any way to do transient analysis on cells from this library using ADE.

Eg. There is a cell named AN2 (2 input AND gate) in my standard cell library. I want to do transient analysis of this cell using ADE.

 

So far what I've done is,

I've imported the complete GDS of the library. I'm able to view the layout views of all cells.

I added a symbol view for AN2.

When i try to do transient analysis using this symbol, i'm getting the following error.

"ERROR (OSSHNL-116): Unable to descend into any of the views defined in the view list, 'spectre cmos_sch cmos.sch schematic veriloga', for the instance 'I18' in cell 'gate_2in'. Either add one of these views to the library 'FSA0A_C_GENERIC_CORE',

cell 'AN2' or modify the view list to contain an existing view."

 

where I18 is an instance of AN2. gate_2in is a schematic entry used as a test bench for the symbol.  FSA0A_C_GENERIC_CORE is the standard cell library.

 

I know that the GDS2 alone doesnt have enough information for a simulation. I want to know if there is any way to add another view so as to do transient or other analysis on the cells using ADE.

 

I'm suing Virtuoso 6.1.5

 

Reagrds,

Jephy

     Hi,

     

    Imported the .cir spice file to virtuoso. It's working fine for me.

    If you have the spectre model for the transistor used in spice file, this is a simple method.

     

    Regards,
