Simulating a logic library (without schematic views) in spectre

Hi,

I have received a logic library of about 50 cells.

Each cell one has a symbol view and layout view, but there is no spectre view and there is no prop.xx file.

There is also a big netlist file with a .subckt model for each of the cells.

I have asked for a schematic view for each cell, but these will not be provided. 

I want to simulate with ADE/Spectre a predominantly analog circuit with a few of these logic blocks as well.

Following the instructions in this link I was able to get an inverter to simulate.

http://community.cadence.com/cadence_blogs_8/b/rf/archive/2009/01/07/tip-of-the-week-how-to-simulate-a-subcircuit-netlist-with-spectre-in-ade

In a nutshell, I copied the symbol view to a spectre veiw and then Edit CDF to add terminal names for termOrder.

[I could add model= also, but that did not seem necessary as the model name and symbol name were identical.]

Do I have to do this for every cell in the library?

Is there any automated way to do it?

Why didn't the foundry deliver the kit with this already done (even if they did want to keep the scheamtics private)?

This is in Cadence IC 5.1.41

Thanks,

John

    That worked too, thanks.

    Now is there a way to generate the schematic views for every cell in the Library from the single netlist file (and the already existing symbols, if needed)?

    Thanks, John
