    stb simulated results different in ADE-L and ADE-XL Reply

    hi,everyone,

    I am simulate a crystal osc ,which main circuit is just a simple nmos with it's drain connected to gate through a resistor.And I put a zero vdc at the drain to do stb analysis.It's oscillate frequency is  25M ,so i choose frequency from 24M to 26M ,linear step ,every step is 100.

    But i found the result is different in ADE-L and ADE-XL.Accroding to the waveform,the results in ADE-XL in right

    i don't know which one i should trust.My cadence version is IC 6.15 and each case i use spectre to simulate.spectre version is 7.2

    thanks any help in advance

    I don't see why the simulation results should be different between ADE L and XL, given that the simulator is the same.

    Maybe you can do a Simulation->Netlist->Display in ADE L, and over the outputs pane in ADE XL do Right Mouse->View Netlist and compare the two? The most likely explanation is that there is some difference in setup between the two cases. You could save the two netlists to some location and then use "diff" on them (say).

    Regards,

    Andrew.
