    SPEED2000 rise time/coupling/coupled lines question Reply
    Dear Sir./Mam.,
    I have some questions on using SPEED2000 
    1. rising time setting
    In TDR-TDT simulation tutorial (16.62)
    Rise time is set as 100ps at 'Net Manager' (p.28), but set as 30ps at 'TDR Differential' window of TDR/TDT setting(p31).
    These two values should be the same or not?
    2. couling (%)
    In TDR-TDT simulation tutorial (16.62)
    How can I calculate the coupling coefficient in the  'Net Manager' (p.28) ?
    Should I use other 2D/3D solver? 
    SPEED2000 will not calculate it by itself?
    3. 'Show Auto Coupled Lines'
    Some part of continuos differential lines are not identified as coupled line.
    In one pair of differential lines, some parts are identified as coupled line, but the other part are not.
    Best regards,
    Joshua
