Traces are accessible by the method "get_trace(trace_ref)" where trace_ref is either the name of the net on the LTSPice Simulation. Normally trace references are stored with the format V(<node_name>) for voltages or I(device_reference) for currents. For example V(n001) or I(R1) or Ib(Q1).
For checking steps in simulations, the method get_steps() should be used. In case there are no steps in the simulation, the class will return a single element list.
NOTE: This module tries to import the numpy if exists on the system. If it finds numpy all data is later provided as an array. If not it will use a standard list of floats.
Below there is an example of the class usage.
LT = LTSpice_RawRead.LTSpiceRawRead("Draft1.raw")
IR1 = LT.get_trace("I(R1)")
x = LT.get_trace(0) # Zero is always the X axis
steps = LT.get_steps()
for step in range(len(steps)):
plt.plot(x.get_wave(step), IR1.get_wave(step), label=steps[step])
plt.legend() # order a legend.
