WebDec 8, 2024 · Abstract. Typically, a production chip consists of several million flip-flops and billions of transistors. All these flops have to strictly adhere to a couple of timing requirements called setup ... WebThe timing violations appear to be on the same clock domain (since they are Intra-Clock paths), so that rules out the most common cause (missing constraints having to do with clock crossing). The magnitude of the failures is very small, but the number is very large.
