Consider a modern client-server/cloud EDA CAD design system as shown in Fig. 1 . Multiple clients use a front-end client application (the cad system interface software program) on their devices (mobile, desktop, laptop, etc) to connect to a cloud back-end system which performs various tasks. In modern systems, like Autodesk 123D Circuits or iSchematics’ Spicy Schematics, in fact many thousands of users connect to the cloud system, and the front-end interface is a software program that runs in the client’s internet browser. The back-end cloud system handles various operations, including managing user accounts and design files, and real-time storage and retrieval of user data.
