Grab a copy of inkscape and look at the various tutorials (while studying some of the included parts DIP IC parts) there really isn't a lot to it, especially if you aren't having to build your own SVG image for the breadboard from scratch. Label it as an L298, and set up the pins and labels the same as the L298, if it were in such a package (in fact, I believe there -is- an SMD version of the L298, which has a more standard pinout/spacing - so you could use that as a model for the fake DIP layout).
What you should do instead is build your own Fritzing component find an part that has the same number of pins as the L298 in a standard DIP IC format. So in Fritzing, you can't easily show a view of the L298 in the breadboard view. You can't plug it into a breadboard without an adaptor PCB, or bending the leads. The reason why there (probably) isn't a part for the L298 in Fritzing would probably be due to the fact that the pinout of the Multiwatt package it uses doesn't have a standard 0.1 inch DIP pinout instead, one row of pins is offset by 0.05 inches (IIRC). Bentuk fisik IC L298 & Modul Driver Motor L298N. Are you sure there isn't one (or one being developed)? I know that L298 -modules- exist (like the ones you can find all over Ebay) - but I am not sure about the 'bare part'? Driver motor L298N merupakan module driver motor DC yang paling banyak digunakan atau dipakai di dunia elektronika yang difungsikan untuk mengontrol kecepatan serta arah perputaran motor DC.
