Description
Creates a new fault rule with the given set of properties.
Arguments
|
?session t_sessionName
|
|
|
Name of a session.
Default: Current session
|
|
?faultType t_faultType
|
|
|
Type of the fault to be inserted.
Possible values:
-
"Bridge" -
"Open (Terminal based)" -
"Stuck-at" -
"Custom"
Default value: "Bridge"
|
|
?resistance t_resistance
|
|
|
Resistance value for the fault rule. When not specified, the resistance value is taken from the global preferences for faults.
Possible values: A positive numeric value in string format.
|
|
?weightExpr t_weightExpr
|
|
|
An expression that defines the fault weighting function. When not specified, the weight expression is taken from the global preferences for faults.
Default value is taken from global fault options.
|
|
?weightFactor t_weightFactor
|
|
|
Weight factor for the fault rule. When not specified, the weight factor is taken from the global preferences for faults.
Possible values: A positive numeric value in string format.
|
|
?inst t_instance
|
|
|
Name of an instance below which you need to inject faults in design hierarchy.
Default: "*"
|
|
?excludeInst t_excludeInst
|
|
|
A space-separated list of instance paths to be excluded while injecting faults.
|
|
?excludeSubckt t_excludeSubckt
|
|
|
A space-separated list of subcircuits to be excluded while injecting faults.
|
|
?faultDevices t_faultDevices
|
|
|
A space-separated list of fault devices on which you want to inject faults.
Default value: "*"
|
|
?pinNames t_pinNames
|
|
|
A space-separated list of pin names on which you want to inject faults.
value: "*"
|
|
?extraOptions t_extraOptions
|
|
|
Additional info analysis options in the syntax supported by the simulator.
|
|
?useNetlistSyntax g_useNetlistSyntax
|
|
|
A Boolean value that specifies whether to use the netlist format for instance names.
Default value: nil
|
|
?enableIEEE2427Mode g_enableIEEE2427Mode
|
|
|
A Boolean value that enables the IEEE 2427 mode in Spectre info analysis.
Default value: nil
|
|
?enableFaultCollapse g_enableFaultCollapse
|
|
|
A Boolean value that enables fault collapsing for the fault rule. This option is overridden by the fault collapsing options provided in the global preferences.
|
Value Returned
|
t
|
A fault rule is successfully created.
|
|
nil
|
In case of an error.
|
Example
The following example shows how to add or create a new fault rule with all default values:
maeAddFaultRule()
=> t
; a new fault rule is added to the maestro session
The following example shows how to add or create a new fault rule to insert bridges of resistance 150 ohms in the design hierarchy under instance I3:
maeAddFaultRule(?faultType "Bridge" ?weightExpr "w * 2" ?inst "I3" ?resistance "150")
=> t
The following example shows how to add a fault rule to insert a stuck-at fault of resistance 100 ohms in the design hierarchy under instance M5:
maeAddFaultRule(?faultType "Stuck-at" ?resistance "100" ?inst "M5")
