Z Transform Function CallZ transform functions are used for E-elements (controlled behavioral sources), which is similar to the Laplace form function (see Laplace Transform for more details).
H(z) denotes the frequency response, where z is a complex frequency variable. Its value is: file:///C:/synopsys/Hspice_P-2019.06-SP1-1/docs_help/hspice7/images/hs_behmod_cntrlsrcs.5.3.09.png

MAXF denotes the Nyquist critical frequency.

H(z) is a rational function, in the following form:

You can use parameters to define the values of all coefficients

Example:
Ehigh_pass out 0 ZTRANS in 0 -0.0082 -0.1793
+ 0.6579 -0.1793 -0.0082 / 1
The Ehigh_pass element statement describes a fourth-order highpass filter, with the transfer function:
