There are many videos at https://www.youtube.com/user/parsysEDA.
Also, Analog Devices Inc. and Power Integration Inc. release their application boards/demo boards in Allegro format.Some of them are really complex, you can inspire from them..
Ok, but does analog devices and power integration release allegro files that i can download and use in the software ?
Also, I am specifically looking for RF/High Speed materials.
Wish there was a tutorial/online training course that dealt with RF PCB design not just PCB design in general.
There are many types of PCB samples there RF,Digital,Analog etc.You can use them to inspire..
RF PCB Design needs some experience and tutorials don't give a rough information about them.You will learn by drawing..
