One embodiment is a method of designing an integrated circuit (“IC”) using an online design platform system comprising a design platform provider, at least one electronic design automation (“EDA”) tool and at least one intellectual property (“IP”) library. The method comprises accessing the design platform provider using a computer remote from the design platform provider, wherein the remote computer is connected to the design platform provider and the accessing occurs via an Internet connection; providing access via the remote computer to the at least one EDA tool and the at least one IP library for enabling a user at the remote computer to design an IC; and providing at least one file comprising a final design of the IC directly from the online design platform system to a designated foundry.
