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...
