model name for normal diode in virtuoso shematic editor

madhusudha
I am using a normal pn diode in circuit. When simulated using ADE L package, an error stating " instance of diode requires a model name first" is shown. What is the model name to be given and where it should be specified? I am not using spectre or Hspice. It is normal diode taken from analogLib.

    Hi madhusudha

    There does not seem to be a sample diode model file in IC61x installation so I think perhaps you can use "nmos4" or "pmos4" device from analogLib, join the gate and drain to form a diode and use the mos model file from:

    $CDSHOME/tools/dfII/samples/artist/models/spectre/basicMos.scs

    You can also create your own diode model file as follows:

    a. Open an empty text file and enter the following:

    model myDiode diode is=1.8e-5 rs=1.43 n=1.22

    b. Save the file and add it as one of the model files in ADE

    c. Specify "myDiode" as the model name

    Dear sir...I tried to create my own diode model...But the file format is not accepted...Can you please give me the screen shorts .It is easy to access the diode from the analog lib.Because i have only 14 days to complete my project.I am using cadence virtuoso 6.1.4 ......My mail id:   davidgnanaraj@karunya.edu.in

    Hi diode model

    Here are the screenshots. By the way, please avoid posting your personal information (email, mobile number, address, etc) on a public forum. : )

    Best regards

    Add as one of the model files in ADE-L (Setup->Model files).
