Reading Step InformationΒΆ

This module defines a class that can be used to parse LTSpice log files where the information about .STEP information is written.

There are two possible usages of this module, either programmatically by running the utility LTSteps, or by accessing data through the class as exemplified here:

from PyLTSpice.LTSteps import LTSpiceLogReader

data = LTSpiceLogReader("Batch_Test_AD820_15.log")

print("Number of steps  :", data.step_count)

# Get the names of the variables that were stepped, and the measurements taken
step_names = data.get_step_vars()
meas_names = data.get_measure_names()

# Print headers for a table with steps and measurements
print('\t'.join([f"{step}" for step in step_names]), end='\t')
print('\t'.join([f"{name}" for name in meas_names]), end='\n')

# Print the data.  First values of all step variables, then values of the measurements
for i in range(data.step_count):
        print('\t'.join([f"{data[step][i]}" for step in step_names]), end='\t')
        print('\t'.join([f"{data[name][i]}" for name in meas_names]), end='\n')

print("Total number of measurements found :", data.measure_count)
