mdlxPart

Create Modelithics component

Since R2023a

Description

Use the mdlxPart object to create a Modelithics^® component. After creating this object, you can add the mdlxPart object to a circuit object and compute the S-parameters of the circuit.

Note

This object requires a Modelithics SELECT+ Library™ or a Modelithics Exemplar Library license. For more information, see Modelithics Libraries for MATLAB.

Creation

Syntax

pobj = mdlxPart(mdlxlib,pnumber,ptype,pvendor,substrate)

pobj = mdlxPart(___,Name=Value)

Description

pobj = mdlxPart(mdlxlib,pnumber,ptype,pvendor,substrate) creates a component object with the part number, part type, vendor name, and substrate available in the Modelithics library. The ptype and substrate arguments set the Type and Substrate properties, respectively.

pobj = mdlxPart(___,Name=Value) sets Properties of the Modelithics part object using one or more name-value arguments. For example, mdlxPart(mdlx,'600S','Capacitors','ATC','Rogers4350B4mil',Value=1.2e-12) creates a 600S capacitor from ATC mounted on the Rogers4350B4mil substrate with a capacitance value of 1.2e-12. Properties not specified retain their default values.

Input Arguments

Component number of the Modelithics component, specified as a string or a character vector.

Example: 600s

pvendor — Vendor name

string | character vector

Vendor name of the Modelithics component, specified as a string or character vector.

Properties

Type — Type of passive component

'Capacitors' | 'Inductors' | 'Resistors'

This property is read-only.

Type of passive component, returned as 'Capacitors', 'Inductors', or 'Resistors'.

Example: Resistors

Dependencies

To set this property, specify input argument ptype as 'Capacitors', 'Inductors', or 'Resistors'.

Value — Value of passive component

real scalar

Value of the passive component, specified as a real scalar. You can specify the capacitance, inductance, and resistance values in farads, henries, or ohms, respectively.

Example: 1e-12

Substrate — Name of substrate

string scalar | character vector

Name of the substrate, specified as a string scalar or character vector. Specify a substrate name from the substrates available in Modelithics SELECT+ Library and Modelithics Exemplar Library.

SimulationMode — Simulation mode

Full parasitic (default) | Ideal | No pad stacks | Simplified parasitic

Simulation mode for the mdlxPart object, specified as one of these:

• Full parasitic — Simulate with parasitics including substrates, pad, and internal

• Ideal — Simulate as an ideal model

• No pad stacks — Simulate without the pad interaction

• Simplified parasitic — Simulate with internal parasitic only

PadLength — Pad length of component

real scalar

Pad length of the component, specified as a real scalar in meters.

Note

You can set this property only if your Modelithics SELECT+ Library or Modelithics Exemplar Library component is pad scalable. To check for pad scalability, refer to the datasheet of the component or use the datasheet function to open the datasheet of the Modelithics component.

PadWidth — Pad width of component

real scalar

Pad width of the component, specified as a real scalar in meters.

Note

You can set this property only if your Modelithics SELECT+ Library or Modelithics Exemplar Library component is pad scalable. To check for pad scalability, refer to the datasheet of the component or use the datasheet function to open the datasheet of the Modelithics component.

PadGap — Pad gap in component

real scalar

Pad gap in the component, specified as a real scalar in meters.

Note

You can set this property only if your Modelithics SELECT+ Library or Modelithics Exemplar Library component is pad scalable. To check for pad scalability, refer to the datasheet of the component or use the datasheet function to open the datasheet of the Modelithics component.

Orientation — Orientation of component in PCB

Horizontal (default) | Vertical

Orientation of the component in the printed circuit board (PCB), specified as either Horizontal or Vertical.

Note

You can set this property only if your Modelithics SELECT+ Library or Modelithics Exemplar Library component is orientation selectable. To check for orientation selectable, refer to the datasheet of the component or use the datasheet function to open the datasheet of the Modelithics component.

Name — Name of component

string scalar

This property is read-only.

Name of the component, returned as a string scalar. The name is a concatenation of the vendor name in pvendor and component number in pnumber.

Terminals — Terminals of component

{'p1+' 'p1-' 'p2+' 'p2-'} (default) | cell array of strings

This property is read-only.

Terminals of the component, returned as a cell array of strings.

ParentNodes — Nodes of parent circuit

vector of integers

This property is read-only.

Nodes of the parent circuit connected to the terminals of the component, returned as a vector of integers. To display the ParentNodes property, add the component to a circuit object.

ParentPath — Full path of parent circuit

string

This property is read-only.

Full path of the parent circuit that the component belongs to, returned as a string. To display the ParentPath property, add the component to a circuit object.

Object Functions

Examples

Add Modelithics Component to Circuit

Set up Modelithics SELECT+ Library™.

mdlxSetup('C:\mdlx_library\SELECT')

Create a new Modelithics library object related to the library you set up.

mdlx = mdlxLibrary;

Search the library for a component that you can mount on the Rogers4350B4mil substrate with the vendor name ATC.

search(mdlx,'Rogers4350B4mil',Vendor='ATC')

The ATC 600S capacitor on a 4 mil Roger 4350B substrate fits the search criteria. Create a Modelithics component object that matches these characteristics.

pobj = mdlxPart(mdlx,'600S','Capacitors','ATC','Rogers4350B4mil',Value=1.2e-12);

Create a circuit named C_ATC_600S_Rogers4350B4mil.

hckt = circuit('C_ATC_600S_Rogers4350B4mil')

Add the Modelithics component to the circuit.

add(hckt,[1 2],pobj);

Set the ports of the circuit.

setports(hckt, [1 0],[2 0]);

Display the Modelithics component.

disp(pobj)

Calculate the S-parameters of the circuit.

S = sparameters(hckt,freq);

Plot the S-parameters characteristics.
