Use the ZX subcircuit from the MISC.LIB (s. the MicroSIM pspice Application Notes, pp. 159-160).

To design a motor model, you basically have to consider how the mechanical quantities (rotational speed, torque, inertia) are related to the electrical ones (current, voltage). You should be able to get the fundamental equations from literature if you can't find them from the scratch. Also the load has to be considered of course.
You can implem

I want to implement the clock sync fuctionality for one of the
devices in pspice.The local oscillator produces oscillations of max 2MHz.The frequency comparator block has to compare the signal from local oscillator with the frequency of signal applied across one more
pin.Based on which frequency is higher the local oscillator must tune

I need some information on how to solve convergence problems (time step too small) when I'm simulating power electronics systems which include analog parts, D latches and abm parts. Also I have large currents and voltages to simulate at 70 kHz. I already read material from orcad's site, changed some settings in simulator and still have problem

When I simulate power electronic circuits in pspice I got large *.dat file as a result (<=2GB). Circuit is very big with abm, digital and analog parts and with large values of voltage, current and requency.
Is there any way how can I change deafult max value for this in pspice which is 2GB (I need bigger) or how can I change some (...)

I am trying to use VCCS source in pspice with specified transconductance value of 50mS. I am using component 'G' in pspice for that. The problem is, although i am putting 50mS in value column of 'G', it still simulates the circuit with transconductance =1S. I don't know what is the reason. Am i using the right component?

I've been working on a power device macromodel based on abm, but I got stuck in convergence issues (transient analysis) when Vdd goes over 100V
I changed RELTOL, ABSTOL, VNTOL, etc., but I wasn't yet able to have it working with higher voltages.
The model is in the attached pdf. I am using pspice from Cadence SPB v16.3

I think you can also choose pspice to do that. You can just use the abm(analog behavior module) devices to modeling the real components. Any difficulties pls let me know the details thus I can show you how to do that via email. My email account is email@example.com.

Enter the schematic in Capture using only components from the pspice folder.
Create a new simulation profile, and simulate it.
For the microphone use a Vsin source with f=1kHz, V=1mV. For C1 use a fixed capacitor value, like C1=250pF.
Choose a simulation time of at least 5ms and a timestep<100ns.
After the transmitter works OK

I'm trying to model the a generic opamp macromodel and now down to the PSRR stage. Please take a look at the attached picture, I was trying to build a 1st order PSRR model using VCCS (G) in the pspice, the ouput connected to a small resistor to minic the temperature variation stuff. But this didnt give me useful result.

I want to circuit modeling rate equation using pspice.
For example :
c1*dv1/dt = v1/a - v2/b + c*v1*v2
that each term refer to a current and v1 and v2 refer as node voltage.
c1*dv1/dt ====> current of a capacitor
v1/a====> current of a resistor
v2/a====> current of a resistor
and my question:
how can I model the last term?
can we use a VC

In pspice, a square root circuit can be easily "designed" by using abm (analog behaviour modelling).
For a real hardware circuit, you can refer to analog multipliers, see an example in the AD633 datasheet
Or use a suitable combination of log/antilog circuits. The basic conce
