Thanks , Jess.
The book seems good, I'll buy and read it.  I guess it should be easy to transfer from SPICE primitives to analog behavioral modeling languages .

Recently, I found  there is some behavioral sources even in Spice 2.
use parameter function, e.g,

v1 1 0 pwl(0 0 10u 10)
v2 2 0 pwl(0 1 10u 2)
r1 3 0 r='v(1)*v(2)'
ib  0 3 1

Then a multiplier is realised. it is like the B element in the IsSpice.
We can use the same way to create any other function.

I came across another book with a pretty good section on modeling and analysis of SMPSs:

"Fast Analytical Techniques for Electrical and Electronic Circuits" by Vatche Vorperian. Cambridge University Press. 2002.

The book has some good comparisons of cycle-by-cycle models and averaged models.

Oh, I'd ever read the introduction about this book, it seems novel , but I did not read the detail. How do you think the way the author used?

I am not sure what you are asking. I have not read the book in much detail yet. However, I saw some presentations on Middlebrook's extra element theorem (discussed in the book) many years ago and it seems quite useful. I am hoping to see some discussion of feedback loops in analog circuits and how to account for loading effects. I mentioned the book because the last chapter covers state space averaged models of SMPs and includes a few comparisons of results from brute force and averaged models. The picture show pretty good agreement between the models.
