<span word="In">In</span> <span word="high">high</span>-<span word="speed">speed</span> <span word="systems">systems</span>, <span word="clock">clock</span> <span word="skew">skew</span> <span word="forms">forms</span> <span word="an">an</span> <span word="important">important</span> <span word="component">component</span> <span word="of">of</span> <span word="timing">timing</span> <span word="margin">margin</span>. <span word="A">A</span> <span word="skew">skew</span> <span word="of">of</span> 1 <span word="ns">ns</span> <span word="is">is</span> <span word="a">a</span> <span word="significant">significant</span> <span word="portion">portion</span> <span word="of">of</span> <span word="a">a</span> 15-<span word="ns">ns</span> <span word="cycle">cycle</span> <span word="time">time</span>. <span word="If">If</span> <span word="the">the</span> <span word="timing">timing</span> <span word="budget">budget</span> <span word="does">does</span> <span word="not">not</span> <span word="allow">allow</span> <span word="for">for</span> <span word="skew">skew</span>, <span word="it">it</span> <span word="is">is</span> <span word="highly">highly</span> <span word="likely">likely</span> <span word="that">that</span> <span word="the">the</span> <span word="system">system</span> <span word="will">will</span> <span word="perform">perform</span> <span word="unreliably">unreliably</span>.3.为什么偏移这么重要？在高速系统中，时钟偏移是时序富裕量的重要组成部分。在一个以15纳秒为周期的时间里，1纳秒的偏移都是很显著的部分。如果时序预算不允许偏移，系统很可能无法稳定运行。4.<span word="In">In</span> <span word="today">today</span>'<span word="s">s</span> <span word="designs">designs</span>, <span word="with">with</span> <span word="clock">clock</span> <span word="rates">rates</span> <span word="over">over</span> 100 <span word="MHz">MHz</span> <span word="and">and</span> <span word="rise">rise</span> <span word="times">times</span> <span word="commonly">commonly</span> 1 <span word="nanosecond">nanosecond</span> (<span word="ns">ns</span>) <span word="or">or</span> <span word="less">less</span>, <span word="designers">designers</span> <span word="cannot">cannot</span> <span word="ignore">ignore</span> <span word="the">the</span> <span word="role">role</span> <span word="interconnections">interconnections</span> <span word="play">play</span> <span word="in">in</span> <span word="a">a</span> <span word="logic">logic</span> <span word="design">design</span>.4.在当今的设计中，时钟速率都超过了100<span word="MHz">MHz</span>，并且上升沿通常只有1纳秒或者更少，设计者不能忽视在逻辑设计中互连的重要性。5.<span word="The">The</span> <span word="faster">faster</span> <span word="clock">clock</span> <span word="rates">rates</span> <span word="and">and</span> <span word="rise">rise</span> <span word="times">times</span> <span word="increase">increase</span> <span word="both">both</span> <span word="capacitive">capacitive</span> <span word="and">and</span> <span word="inductive">inductive</span> <span word="coupling">coupling</span> <span word="effects">effects</span>, <span word="which">which</span> <span word="makes">makes</span> <span word="cross">cross</span> <span word="talk">talk</span> <span word="problems">problems</span>&<span word="nbsp">nbsp</span>;gre<span word="ater">ater</span>. <span word="They">They</span> <span word="also">also</span> <span word="mean">mean</span> <span word="shorter">shorter</span> <span word="time">time</span> <span word="for">for</span> <span word="reflections">reflections</span> <span word="to">to</span> <span word="decay">decay</span> <span word="before">before</span> <span word="the">the</span> <span word="data">data</span> <span word="is">is</span> <span word="clocked">clocked</span> <span word="and">and</span> <span word="read">read</span>, <span word="which">which</span> <span word="decreases">decreases</span> <span word="the">the</span> <span word="maximum">maximum</span> <span word="line">line</span> <span word="length">length</span> <span word="that">that</span> <span word="can">can</span> <span word="be">be</span> <span word="used">used</span> <span word="for">for</span> <span word="unterminated">unterminated</span> <span word="systems">systems</span>.5.更快的时钟速率和上升沿都将增加电容耦合及电感耦合效应，这使得串扰问题更加严重。这也意味着在数据被写入和读取之前的反射衰减时间更短，它减少了无终端系统中最大的可用线路长度。更多精彩内容，请继续关注本网站。</p>
