For gate level simulation that has been annotated with an SDF file, when there's a setup/hold violations on a flip-flop the following will happen by default: (1) The FF's output will change to 'X'. (2) a timing violation assertion will be generated. But, what's the effect of +notimingcheck verses +no_notifier. WebWhen we open the analysis view, we will be presented with information under the module hierarchy, indicating which module if any, is presenting a timing violation or initiation interval violation. If we only want to focus on the violations, we can click on the timing or II violation button at the top of the module hierarchy.

Poor timing may cause a gate-level model to report hundreds of hold time violations per clock cycle during a simulation run, for instance, whereas a purely algorithmic model is simply not concerned with physical time. To complicate things … WebA race condition or race hazard is the condition of an electronics, software, or other system where the system's substantive behavior is dependent on the sequence or timing of other uncontrollable events. It becomes a bug when one or more of the possible behaviors is undesirable.. The term race condition was already in use by 1954, for example in David A. … the common group

WebSETUP FIXES During Placement Stage: Timing path groups: We can use this option to resolve Setup timing during placement stage. Groups a set of paths or endpoints for cost function calculations. The delay cost function is the sum of all groups (weight * violation), where violation is the amount for which setup was violated for all paths within the group. WebApr 14, 2024 · Multicycle exception can solve timing violations caused by incorrect timing analysis (wrong launch and lath edge relationship ect.), but multicycles can't be considered as remedy for any REAL timing violation. If you apply multicycle exception but your design does not work like that timing analysis will be incorrect.

WebJust looking for loop-carried dependences and port conflicts will get you rid of the bulk of II violations.
