Write Verilog-A description of rational function object
status = writeva(h,filename,innets,outnets, ...
discipline,printformat,filestoinclude)
status = writeva(h,filename,innets,outnets,discipline,printformat,
filestoinclude)
writes a Verilog-A module that describes a rational function object
h to the file specified by
filename. The method implements the object in
Verilog-A using Laplace Transform S-domain filters. It returns a
status of True, if the operation
is successful, and False if it is unsuccessful.
h is the handle to the rational function object.
Typically, the rationalfit function creates this object
when you fit a rational function to a set of data.
filename is a character vector representing the name of
the Verilog-A file to which to write the module. The
filename can be specified with or without a path
name and extension. The default extension, .va, is added
automatically if filename does not end in this extension.
The module name that is used in the file is the part of the
filename that remains when the path name and
extension are removed.
innets is a character vector or a cell array of character
vectors that specifies the name of each of the module's input nets. The
default is 'in'.
outnets is a character vector or a cell array of
character vectors that specifies the name of each of the module's output
nets. The default is 'out'.
printformat is a character vector that specifies the
precision of the following Verilog-A module parameters using the C language
conversion specifications:
The numerator and denominator coefficients of the Verilog-A filter.
The module's delay value and constant offset (or direct feedthrough), which are taken directly from the rational function object.
The default is '%15.10e'. For more information on how to
specify printformat, see the Format specification for
fprintf.
discipline specifies the predefined Verilog-A discipline
of the nets. The discipline defines attributes and characteristics
associated with the nets. The default is
'electrical'.
filestoinclude is a cell array of character vectors that
specifies a list of header files to include in the module using Verilog-A
'`include' statements. By default,
filestoinclude is set to '`include
discipline.vams'.
writeva only accepts a single rational fit
object. It does not work with an array/matrix of rational fit
objects

Manual.
