As a result, hardware simulations can yield highly accurate and easily automated pre-silicon estimates for e.g. timing and area figures. In this work we design, implement, and evaluate CASCADE, a framework that combines a largely automated full-stack standard-cell design flow with the state of the art techniques for side channel analysis. We show how it can be used to efficiently evaluate side channel leakage prior to chip manufacturing. Moreover, it is independent of the underlying countermeasure and it can be applied starting from the earliest stages of the design flow. Additionally, we provide experimental validation through assessment of the side channel security of representative cryptographic circuits. We discuss aspects related to the performance, scalability, and utility to the designers. In particular, we show that CASCADE can evaluate information leakage with 1 million simulated traces in less than 4 hours using a single desktop workstation, for a design larger than 100kGE.Keyphrases: design-time analysis, hardware simulation, side-channel analysis, Standard Cell Design In: Lejla Batina, Ulrich Kühne and Nele Mentens (editors).
