Transformer-based termination with PAM3 PWL test vector. Figure 29. An output of the PWL voltage source. Figure 30. Eye diagram display of the PWL voltage source and cable side differential voltage. Conclusion LTspice is a powerful and free simulation tool, which can be used ...
In LTspice, insert the ±10 mV AC injection voltage source and injection resistor and label nodes A, B, and C as shown in Figure 2. The AC voltage source valueSINE(0 10m {Freq})sets the 10 mV peak and sweeps the frequency. The user can play with peak sine values between 1...
I seriously doubt LTSpice is written to use hardware acceleration in the GPU, which would otherwise be an explanation since that would not appear in Task Manager's CPU info. Another thought which occurred to me just now is that perhaps he's memory bottlenecked, with the CPU waiting around ...

The GLaplace component is used in SPICE to describe a frequency-dependent impedance or resistance. Each frequency-dependent element (Rvar1, Rvar2, Lvar) is modeled in LTspice using the GLaplace G2 voltage dependent current source. Creating the Model in LTspice ...
You appear to want to apply +/- 5 volt supplies to it in your sim. If lowering the supply to the correct range doesn't work try putting 10 ohm in series with the signal source V1. EDIT following change to OP's circuit: -
Voltage controlled current source with time. I can make a part that is a formula having many inputs, time, frequency, voltage, temp., current, etc and outputs almost anything. C carbonzit Well-Known Member May 17, 2011 #8 I think I got it. It runs. Now I'd like to find out ...
The problem here is that LTSpice is unable to differentiate the function of the PWM voltage source. Its differential is zero at any point in time except for those when it switches (at which it's undefined). This trips up LTSpice's automatic timestep calculation...
