Help with complete understanding of "vsin" source in Cadence

jdp721
Hi.

I kind of thoroughly Googled before posting this question for seeking help from you guys! 

The "vsin" source (in analogLib) of Cadence has many parameters: 

i) AC magnitude, AC phase, DC voltage
ii) Offset voltage, Amplitude, Frequency,...

Question 1: Internet resources are indicating that parameters in (i) are for AC analysis, while that in (ii) are for Transient analysis - IS THIS TRUE? - because, I have seen in Cadence that changing the "AC phase" led to change in the Transient output waveform - is it so that the "AC phase" field is common between AC and Tran analyses?

Question 2: what is the use of the "DC voltage" in (i) above? - because, I am seeing that people are setting this to '0 V' most of the times without any explanation!

    One more thing...

    Use the Tool Filter (In IC616, go to Options-Tool Filter) to limit what parameters are displayed in the schematic and in the Edit Properties/Add Instance form.

    For example, if you choose hspice (and deselect all others) and OK the form, you will see a different parameter set than if you check spectre (and deselect all others).

    best regards,
