AMS: Grid not seen in Waveforms

medeepak

Hi

I imported a Verilog code for not gate and tried to simulate it by giving a pulse signal as input varying from 0 V to 5 V.

I tried to simulate it using AMS simulator in ADE L

In the output waveform i get doesnth have any value on y axis and the Show Grid button is disabled

 Can anone guide me about to correct this

Thanks in advance

 Regards

  • Hi

     

    I am sorry fr giving less details

    i tried to import a Not Gate verilog in to Virtuoso (IC 6.1.3.1) through the verilog in form

    the not gate code :

     

    module notgate(b,a);

    output b;

    input a;

    assign b =~a;

    endmoudule

    after i imported it i created a schematic cell view with the input of not gate as a pulse voltage source (voltage varying from 0 to 1.8V with rise time 1ns, fall time 1ns, pulse width as 5ns and time perion as 10ns)

    and the output was attached to an output pin

    later i created its config view with AMS template

    in the ADE L window i selected AMS simulator, gpdk.scs as model library ans spectre as solver

    when i do run the ADE i get an output waveform that has no values in its y axis

    my specctre version is 78.2.0

    what could be the possible source of error

    if i had missed any piece of information kindly point it out 

    regards
