Dear all,

Hi!

I'm trying to do a Harmonic Balance (HB) Large-Signal S-Parameter (LSSP) simulation to figure out the input impedance of a nonlinear circuit.

Through this simulation, what I want to know is the large-signal S11 only (not S12, S21 and S22).

So, I have simulated with only single port (PORT0) at input, but LSSP simulation is terminated and output log shows following text.

" Analysis `hb' was terminated prematurely due to an error "

The LSSP simulation does not proceed without second port.

Should I use floating second port (which is not necessary for my circuit) to succeed the LSSP simulation?

Does the LSSP simulation really need two ports?

Below figure is my HB LSSP simulation setup.

Additionally, Periodic S-Parameter (PSP) simulation using HB is succeeded with only single port.

What is the difference between PSP and LSSP simulations?

Hi Folks, A question that I've often received from designers, "Is there a method to determine the amount of memory required before I submit a job? I use distributed processing and need to provide an estimate before submitting jobs." The answer...(read more)

hi everyone, 

i'm trying to create a netlist for aging simulation. i would like to simulate how power, Gain and PAE (efficiency) are inlfuenced after 3 hours

i would be grateful if someone can correct my syntax in the netlist since i'm trying to make a sweep HB  simulation where the input power is the parameter.

i did it without any error for the sp (S parameters)  simulation.

you can see the images for both sp and hb simulation netlists. (from left to right: sp aging netlist; hb aging netlist)

i will be grateful if someone can provide me some syntax advices.

thanks,

best regards
