Rcd clock latency

WebJul 22, 2024 · PCIe is one of the most latency-sensitive forms of serial communication because its address-based semantics mean that processor threads are often waiting for the results of a transaction. The advent of PCIe 4.0, and especially of PCI 5.0, have driven the need to use retimers in many longer-reach PCIe applications. WebFeb 20, 2024 · 2. The set_clock_latency constraints are used to specify the clock latency through the STARTUPE2 primitive and board trace when it arrives at the SPI Flash. The insertion delay includes the propagation delay from USERCCLKO to CCLK pin and the trace delay on the board.

Weblatency_max_rise *should* be reporting the value you're looking for. It sounds like a bug to me. Are you trying to get the latency preCTS or postCTS? If preCTS, is the latency on the CK pin you're querying asserted on the pin itself? Somewhere upstream from the pin? Or on the clock that is connected to the pin?
