Hello,

I am new at in the domain of Verilog-A and the design of systems.

I'm working as research assistant since some weeks and should
replace system designs with SDD's from Agilent ADS with Verilog-A.

I have the problem that I don't know how I could change the used
state equations from the 5-port SDD for using in Verilog-A.

The problematic formula are only implicit equations:

F[3,0]=t0n*(_v3-vst)/tau3
F[3,1]=t0n*_v3

At most the weighted function in frequency domain with complex numbers is a ploblem for me.

F4[4,0]=_i4
F4[4,4]=_v4*_v2
H[4]=(rth/WF)/(1+j*2*PI*freq*tauD)

Can anyone help me to solve my problem?

Thanks a lot
