DVM - Design Verification Module
|
The Source column allows you to specify the subcircuit definition and parameters for a DVM source. The source column can be blank.
The following table describes the acceptable source configurations.
Function | Description |
Dc() | Configures a DC source with the specified DC voltage. |
Ramp() | Configures a PWL source with the specified voltage levels. |
Pulse() | Configures a PWL source with the specified voltage levels |
Saw() | Configures a sawtooth source with the specified parameters. |
Squ() | Configures a square wave source with the specified parameters. |
Tri() | Configures a triangle wave source with the specified parameters. |
Pul() | Configures a pulse source with the specified parameters. |
PulZRFT() | Configures a zero rise and fall time pulse source with the specified parameters. |
Sin() | Configures a sinusoidal source with the specified parameters. |
Cos() | Configures a cosinusoidal source with the specified parameters. |
Exp() | Configures an aperiodic exponential decay pulse source with the specified parameters. |
AcFixed() | Configures a standard sine wave input voltage source with the specified RMS voltage and frequency. |
AcDropout() | Configures an AC source with line dropout starting from and returning to the specified RMS voltage and frequency. |
AcStartup() | Configures an AC source which starts at 0 volts and turns into an AC voltage source with specified RMS voltage and frequency. |
AcSurgeSag() | Configures an AC source which starts at the normal RMS voltage and steps to the RMS sag or surge voltage before returning to the normal RMS voltage. |
AcQSW() | Configures a Quasi-Square-Wave source with specified pulse parameters. |
AcGlitch() | Configures an AC source with the specified
RMS voltage and frequency.
>This source can be configured to simultate a broad range of abnormal AC Line voltage conditions. |
SubCkt() | Configures the subcircuit definition using SUBCKT_NAME. |
Source() | Configures the subcircuit to use
the specified DC voltage without changing the subcircuit definition.
Note: Most often used with Full Power Assist to change input voltage levels without overriding configuration changes resulting from the use of an Analysis/Objective specification. |
AcSource() | Changes the subcircuit parameters but does not change the subcircuit
definition.
Note: Most often used with Full Power Assist to change input voltage levels without overriding configuration changes resulting from the use of an Analysis/Objective specification. |
To configure managed sources, follow these steps:
Subcircuit definitions for the various source configurations are defined in the following topics
