In an ideal world, Dr. Dinges says, people would go to sleep a little bit earlier and not use an alarm clock at all. 丁格斯博士说,在一个理想的世界中,人们应该稍微早点儿上床睡觉,而且根本不用闹钟。
Not my ideal alarm clock! 这可不是我理想中的闹钟!
The power-law spectrum coefficients of individual precision clock can not be obtained via measurement, because there is not ideal clock which can be regarded as reference clock. 由于不存在实际可用的理想时钟作为参考,用以估计幂律谱系数的单钟噪声无法直接测出,而只能利用钟组内各钟之间的钟差。
As the key part of a timing driven design, clock tree synthesis and optimization is very special in a hierachical design and tool should calculate the actual clock network delays after the clock tree is built instead of using ideal clock. 作为时序设计的核心,时钟树的综合和优化在层次化流程中有其需要特别设计的地方,而时钟树综合之后要使用真实的时钟而非理性时钟来进行时序分析。
