Do you know software for drawing logic circuits with "logic gates"?

Question

Informatics

I am reading a book by Charles Petzold "Code. The Secret Language of Computer Science". There was a desire to "assemble" some components, like an adder, from "gates" virtually. Tell me the software that emulates the operation of the "gates". Google did not give what we would like!
