Implementing an analog behavior model with TIME variable dependency means to include an independent source to the model. Although the option is provided by the pspice abm syntax, it's not genuine behavior modeling. I didn't yet experience a simulation case where a similar combination seemed useful. If there's a time dependency to be modeled, it can

i am trying to design a sigma delta modulator in pspice by abm library , here it is my schematic , nut it dont work!
first block subtract the input from output , then the result goes to integrator and then if the result is positive the output becomes 5 , else the output becomes zero and this output goes to 74175 that its clock rate is 10k

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

It is still showing transconductance of 1S
Looks like. But it's surely not a general pspice problem. You may want to inspect the generated netlist. Or post the project files.

Right now I've a Laplace abm-Filter(PI Filter) in my pspice Simulation. I want to replace the Laplace abm-Filter with a real OP-Amp. My question is, will the Vcc+ and Vcc- of the Op-Amp influence my 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

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 (...)
