Thank you so much for your reply. I checked the python file for the ClockRecoveryComponent.osd project.
there are several packages like:
import numpy as np
import math
import tempfile
import sys
sys.path.append(‘/Temp/PythonScripts/PythonSignalLibrary’) #the directory that contains CDS_SystemManager
sys.path.append(tempfile.gettempdir() + ‘/OptiSystemTempDir’)
from SystemManager import *
from CalculationResult import *
from SignalLibrary import *
where can I download the three modules: SystemManager, CalculationResult,SignalLibrary?
