I have a problem with a amplifier Class D simulation.
It works, but the simulation freeze during a long time after few µs. I see a simulation speed at fS/s .
You are probably fighting transient convergence challenges.
Hard switching nodes fed back to slow circuitry is one such.
Use of too-ideal behavioral sources and active devices with
their parasitics neglected, can also be trouble.
I like Euler method because it is more "self-damping" than
TRAP or TRAPGEAR.
Hello, @stenzer et @dick_freebird Thank you for your answers.
I change the solver to "alternate",and it fix the problem of freeze. I don-t understood the difference between both solver but it works.
@dick_freebird How can i choose a euler method in ltspice ?
