The IBIS model is used to help get exact information in the integrity constraint design of system board level or multipleboard level signals for analysis and calculation.
IBIS模型可以帮助设计者在系统板级或多板信号完整性约束的设计中获取准确的信息，以进行分析和计算。

As noted earlier, it is important for compliance with board rules that either a justification for sole source exists or an appropriate choice is selected from multiple submitted bids.
Hundreds of tiny transistors, chips, and other electronic parts are attached to each circuit board by "pick and place" robots, whose multiple arms move almost too fast to follow.
