WebScan Chains: PnR Outlook. 1. INTRODUCTION. Chips without DFT implementation will mostly have only one timing mode of operation and hence just one timing mode in … WebScan chain design is an essential step in the manufacturing test flow of digital inte- grated circuits. Its main objective is to generate a set of shift register-like structures (i.e., scan chains), which, in the test mode of operation, will provide controllability and observability of all the internal flip-flops.
