Note

spectre -h <name>

Displays help information for the specified keyword <name>

Example: spectre -h sweep

Elements of syntax

General remarks:

• Comments are indicated by a double slash (//)

• Spectre is case sensitive

Names of components, nodes, instances, parameters:

• Do not use the name of an analysis or a primitive

• Component name must start with a letter, nodes can be represented by integers

Component instance

A component instance in the has the following general form:

Name given to the component	Connected Nodes	Model or primitive	Parameter(s) Value(s)
R1	(b1 0)	resistor	r=10k

Some common primitives

• capacitor capacitor model

• inductor inductor model

• resistor resistor model

• isource independant current source

• vsource independant voltage source

Analysis commands

The general form for an analysis command is as follows:

Analysis name	Nodes (optional)	Type of analysis	Parameters
myResponse		tran	stop=2us
