Hello everyone,

Please help me to write VerilogA code to generate a pulse sequence with different amplitudes for every time period within a single transient analysis.


I just want to generate it like amplitude modulation but that high amplitude value should vary using a random function.

Please help.

Dear Ken,

Thank you for your reply.
I'm trying to resolve my problem. But it seems I did not elaborate on my problem clearly.

I want to add some random value to the pulse source, like noise, by using random or any other function.

Please check the image. I tried to explain my problem.

Dear Ken,

Thank you so much for your reply.

I tried to simulate it with a random function, but transient analysis takes only one value.

See
1. Firstly, I gave the current pulse source a height of 10 pA.
2. Then I call the verilog-A file where I can add a random value to the
   height of the current source pulse. Like 10 pA ± n% 10pA
    where n is the randomness percentage of the height which we can
    control.
3. Then, after generating a current pulse with a random height, we can feed the data to the main circuit.

But, I'm not able to generate it using HSPICE with verilog-A.

Please help me to find out the way.
