Model Definition Line

The model definition line identifies the name of the model, the inputs and outputs on the model, and the names and initial values of any model parameters. The netlist syntax for the model definition line is:

% NEXSYS Functional_Model(“model_name”, “In_N”, “In_Types”, “In_Num_Sample_Needed”, “Out_N”, “Out_types”, “Out_Num_Sample_Generated”, “data_flag”, “probe_domain”, “parameter_string”)

Note

Each entry in the parentheses ( ) must be double quoted, or else an error occurs.

**Nexsys MATLAB UDM Netlist Entries**
Netlist Entry	Description
model_name	The name for the MATLAB UDM
In_N	The number of input ports
In_Types	A character string of length In_N specifying the data type for each corresponding input port. The characters are r for real, c for complex.
In_Num_Sample_Needed	The number of input samples needed per invocation (execution) of the model. This entry can be an expression using the parameters listed in the parameter_string entry.
Out_N	The number of output ports
Out_Types	A character string of length Out_N specifying the data type for each corresponding output port. The characters are r for real, c for complex.
Out_Num_Samples_Generated	The number of output samples generated per invocation (execution) of the model. This entry can be an expression using the parameters listed in the parameter_string entry.
data_flag	Flag. Set to DATA_REQ when external data needed, NO_DATA_REQ to reset.
probe_domain	Domain for displaying probe data: TF_DOM for time and frequency domain FREQ_DOM for frequency domain only SWEEP_DOM for sweep domain NOT_APPLICABLE for non-probe elements
parameter_string	List of keywords, optionally with default values (keyword=val) separated by commas.
