Inspired partly by curiosity to learn about signal processing and controls and partly by Matlab simulink , which can simulate circuits as well.   ( https://in.mathworks.com/help/physmod/sps/powersys/ug/building-and-simulating-a-simple-circuit.html ) (where we can  directly include components like lpf and integrator as blocks). I thought it would be nice to have such blocks in open source for ngspice. ( http://ngspice.sourceforge.net/ )   Installation this tool box is built as a ngspice code model and can be compiled along with ngspice as described in the manual ( http://ngspice.sourceforge.net/docs/ngspice-34-manual.pdf ).   This tool is being developed in a separate fork of the main ngspice branch which can be cloned from here :     https://sourceforge.net/u/harshcht/ngspice/ci/master/tree/ Then build ngspice using the steps described in section 32.1.2 of the user manual.   Examples the main example file (feedback_example.cir) is an example ...
