Model Usage

Instance Syntax

BSIMSOI instances can have 4 to 7 terminals: drain (d), gate (g) source (s), back-gate (e), external-bulk (p), bulk (b), and temperature node (t). When more than 4 terminals are given, instance parameter “tnodeout” is specified, the last terminal is interpreted as temperature terminal. All the possible terminal connects are follows:

• InstanceName d g s e ModelName parameter=value
• InstanceName d g s e [p] ModelName parameter=value
• InstanceName d g s e [p b] ModelName parameter=value
• InstanceName d g s e [p b t] ModelName parameter=value
• InstanceName d g s e [t] ModelName tnodeout=1 parameter=value
• InstanceName d g s e [p t] ModelName tnodeout=1 parameter=value
• InstanceName d g s e [p b t] ModelName tnodeout=1 parameter=value

To specify BSIMSOI instance element, the ModelName has to be associated with a BSIMSOI model card.

Sample Instance Statement

MN1 (Vd Vg Vs Ve ) nmos_soi1  l=1e-6 w=5e-6

Model Syntax

The following syntax specified BSIMSOI model:

model ModelName bsimsoi parameter=value ...

The third parameter, bsimsoi, is the master to indicate this model is a BSIMSOI model card.

Sample Model Statement

model bsimsoi_nmos1 bsimsoi type=n version=4.0 tnom=25 tox=3.0e-9 tsi=41e-9 tbox=100e-9 toxm=3.0e-9 vth0=0.29 nch=4e17 nsub=1e16 rbody=0 rbsh=0
