techCreateElectricalRuleTable

techCreateElectricalRuleTable( 
d_techID 
t_constraintName 
l_indexDefinitions 
tx_layer1 
[ tx_layer2 ]
) 
=> t / nil

Description

Creates a current density table and indexes for the named layer attribute in the specified technology database. ASCII technology file location: currentDensityTables subsection of the layerRules section. To create table entries, use techSetElectricalRuleTableEntry. If a currentDensityTables subsection does not exist, this function creates one. If a current density table already exists for the named attribute applied to the specified layer or layers, this function replaces it; the original table entries are deleted.

Arguments

d_techID	The database identifier of the technology database.
t_constraintName	The name of the electrical constraint. Valid values: `peakACCurrentDensity`, `avgACCurrentDensity`, `rmsACCurrentDensity`, `avgDCCurrentDensity`
l_indexDefinitions
	A list defining the name of the index or indexes for the table. The list has the following syntax: `list( [` t_index1Name`] nil nil [`t_index2Name `] nil nil )` where, t_index1Name is the name of the first dimension of a two-dimensional table or the only dimension of a one-dimensional table. Valid values: Any number or string t_index2Name is the name of the second dimension of a two-dimensional table. Valid values: Any number or string
tx_layer1	The first layer on which to apply the table constraint. Valid values: The layer name, the layer number
tx_layer2	The optional second layer on which to apply the table constraint. Valid values: The layer name, the layer number

Value Returned

`t`	The current density table was created.
`nil`	The current density table was not created.

Example

techCreateElectricalRuleTable(tfID "peakACCurrentDensity" 
list("frequency" nil nil  "width" nil nil) "Metal1")
=> t

Creates the table electrical rule peakACCurrentDensity with the indexes frequency and width applied to layer Metal1 in the technology database identified by tfID.
