    Hi, all,
    Sometimes I just don't quite understand why Cadence creates so many
    tools/language for the simulaton task. For Star-hspice, basically there
    are only two components, simulator and aWaves. In the hspice netlst,
    you can include circuit netlist (data statements), model,
    analysis/command statement and output statements all together, then
    plot the data using aWaves. However, for Cadence simulaton, why do we
    need so many tools, and why can't we put something like
    phaseMargin(VF("/Vo")) or the voltage difference etc all in the spectre
    netlist? Why we have to use OCEAN script to invoke these SKILL
    functons?
    Seems to me hspice is a more easy, well organized simulation enviroment
    than Cadence Spectre (plut ocean, SpectreMDL, ADE......). Can anyone
    comment on this?
    thank you,
    Jay
    p.s.: BTW, Cadence's documentation is also hard to use. With hspice
    manual, users can easily find and learn how to do different
    simulation/characterizaton...
