Which software do designers and researcher use to create circuit diagrams for datasheet/publication? I used Cadence for the entire flow. But the schematics is not good for publication. Is there any tool take Cadence schematics and convert it to LTSpice schematics? Because I can find some package that converts LTspice schematics to TeX figures. I feel stuck.. any help would be greatly appreciated.

@User For optimum results I use

circdia

which is based on

TikZ

. You need to put in the effort, though, takes longer than any drawing solution. https://github.com/hpretl/iic-circdia

Thanks for your answer. In past I have used LaTeX for creating document but not figures. Do we have to write coordinates of wires in code or there is some GUI assistance as well?

@User No GUI, unfortunately.

For smaller schematics in LaTeX documents, I’ve been really happy with the circuit macros package. https://ece.uwaterloo.ca/~aplevich/Circuit_macros/

Thanks @User
