SPICE Environment Parameters

Set parameters that apply to all connected SPICE-compatible blocks

Library

Utilities

Description

The SPICE Environment Parameters block lets you set parameters that apply to all SPICE-compatible blocks in an electrical network:

• Circuit temperature

• Minimum conductance

If your Simulink^® model does not contain a SPICE Environment Parameters block, all blocks use the default values of these parameters. You must connect every network in the system to a SPICE Environment Parameters block to override the default values.

Note   The simple semiconductor models in the Semiconductors sublibrary are not temperature dependent, so the SPICE Environment Parameters block only changes the minimum conductance parameter used by the exponential diode and bipolar transistor models.

Dialog Box and Parameters

Circuit temperature

The temperature of the connected SPICE-compatible blocks. The default value is 300.15 K.

Minimum conductance GMIN

The minimum conductance used by some blocks. The default value is 1e-12 1/Ω.

Ports

The block has the following ports:

OUT

Electrical output.

Solenoid
