Hi, I am using Virtuoso IC6.1.5 with IBM BiCMOS8HP technology. It runs well in ADE for analog design. But when I imported digital library of this technology,draw a basic circuit schematic with AND block, and include .scs file and verilog file for this AND block, the simulation was not successful. The error message showed here is
*INFO* (icLic-25) License
Analog_Design_Environment_XL ("95210") was used to run ADE L.

Could anyone teach me if there is any mistake I make in ADE setup in order to run this circuit? Thank you very much!
If your digital library only has verilog descriptions, you won't be able to simulate it with spectre; spectre is an analog circuit simulator and like other SPICE-like simulators, doesn't handle logic level verilog descriptions.
For that you'd need to use "AMS Designer" (ams as the simulator in ADE). I suggest you start with the AMS Designer Tutorial in the documentation.
In reply to Andrew Beckett:
what files are needed to run Spectre on digitial elements (like NAND, NOR,.. ) ? We have a PDK installed but I am not sure if the necessary files for analog sim of the digital elements are included. Could you give me a kick in the right direction ?
In reply to marten:
Does the library of digital elements have schematics?
yes there are schematics available for nearly every element. Also I found a bunch of *.scs-files within the PDK.
You're probably good to go then. You might want to check with the provider though - they ought to document what they support...
Thanks for the quick reply!
Maybe you can give a short overview how to load these files into ADE ?
If you have schematics, then I wouldn't have thought you need the .scs files if they are describing the same cells.
As I said, you should ask the provider precisely what you are supposed to do as this can vary from supplier to supplier. I can't really guess without seeing what information you have.
Okay I will do so.
Thanks for your help!
