延迟平衡
R2026b当优化或模块实现选项在模型中的关键路径中引入延迟时，原始模型与生成模型或 HDL 代码的数值计算在某些时间步可能会彼此不同，因为在其他并行信号路径中并未引入等效延迟。通过延迟平衡，HDL Coder™ 检测沿一条路径引入的延迟，然后在生成模型中的其他路径中插入匹配延迟。

Delay Balancing and Validation Model Workflow in HDL Coder
How HDL Coder™ can automatically balance delays within a model. HDL Coder may introduce additional delays in the HDL implementation for a given model. These delays may be introduced by either certain block implementations or by optimizations for the purpose of improving the efficiency of the hardware implementations. However, introducing delays on only certain paths can result functional behavior that is different from the original intent of the user model, thereby violating functional equivalence between the original user model and the HDL implementation.
