how to search a specific components for a typical circuit design
If i have to design a circuit to realize given by equation
W= 5(X*Y) - 4Z using opamp
If you want to use mathematical equations to realize a circuit, you can use OpenModelica tool.
Then that circuit can be implemented in eSim.
It helps to understand the circuit, especially when the components are not available in stores. In my case, I have to search for the components from my own computer and build them by myself.

This is something that I can do only if I have enough knowledge and skills regarding electronics.
