Web17 Jan 2024 · Negative timing check delays did not converge, trying to solve by setting minimum constraint to zero. 当2个以上的timing check使用同一个reference event(比如 posedge ck)，且这些timing check检查的时间窗口没有重合时，EDA工具没办法处理这种情况，即负延时检查没有收敛。 Web3 Mar 2024 · Questions to ask when Debugging a Setup or Hold Violation: Is the design properly constrained? At a minimum, every design should have PERIOD, OFFSET IN, and OFFSET OUT constraints. Are all of the paths going to this register covered by the timing constraints you have added to the design? thomas oklahoma weather

Web9 Sep 2012 · The 'reference_event' must be an edge-triggered event: posedge or negedge. A timing violation occurs if the time interval between an edge-triggered reference event and a data event exceeds the 'limit'. If a reference event and data event occur at the same time, a timing violation is reported. If a 'reference_event' argument is specified without ... Web系统任务 $setup 用来检查设计中元件的建立时间约束条件，$hold 用来检查保持时间约束条件。其用法格式如下： $setup(data_event, ref_event, setup_limit); data_event: 被检查的 … Web8 Dec 2024 · Best ways to avoid and fix hold time violations. The fundamental rule to solve hold time violation is to ensure slower data path logic than clock path logic. In other … uhw gastroenterology
