Hi,

I'm new to ac analysis in Verilog.

Models in Verilog has

Q = ddt(q)
I(p,n) <+ Q

What happens to ddt(q) during an ac analysis?
Can I display the value of Q as a function of f
by strobing Q while running an AC?


thanks.

Thanks Ken.

In your varactor example, how will I then
check the frequency characteristics of q, ddx(q)
and i(p,n)?

after an ac analysis, the only outputs are the
Re and Imag parts of node currents and voltages
as a function of frequency.

how can i output other variables like
capacitances as a function of frequency?
in varactor, for example,
how can i extract dq/dV as a function of freq?
