NGSPICE simulation error( in Python Plot)

While simulating 1-bit LOGIC BLOCK circuit, using the NGSPICE simulation window,it takes 10sec and shows " NGspice taking too long for simulation. check the Netlist file to change simulation parameters."(see image below). basically, I am not getting the PYTHON plot window in esim although I am getting the NGSPICE plots.

so my doubt is about, how to get Python Plots ? do i need to change the simulation parameters? or it is a software issue?

This is mainly because if the transient analysis value is too large, the py plots will not be generated.
