techGetElectricalRules(
d_techID
)
=> l_electricalRules / nil
Description
Returns a list of all of the current density layer attributes and antenna models constraints defined in the specified technology database. ASCII technology file location: currentDensity subsection of the layerRules section and the antennaModels section of the foundry constraint group.
Arguments
|
d_techID
|
The database identifier of the technology database.
|
Value Returned
|
l_electricalRules
|
A list of lists containing the electrical attribute and antenna models settings. The following syntax is used to return current density layer attributes:
( ( t_constraint g_value lt_layer1 [ lt_layer2 ] ) … )
where,
-
t_constraint is the name of the electrical constraint.
-
g_value is the value of the electrical constraint.
-
lt_layer1 is the first layer.
-
lt_layer2 is the second layer. Only returned for two-layer constraints.

The following syntax is used to return antenna model constraints:
("nameAntennaRule"
( l_areaRatio
l_sideAreaRatio
l_l_diffAreaRatio
l_diffSideAreaRatio
l_cumAreaRatio
l_cumDiffAreaRatio
l_cumSideAreaRatio
l_cumDiffSideAreaRatio
nil
nil)
t_layerName )
where,
-
name is the antenna oxide model name:
default, second, third, or fourth -
l_areaRatio is the no-side area ratio.
-
l_sideAreaRatio is the side area ratio.
-
l_diffAreaRatio is the no-side diffusion area ratio.
-
l_diffSideAreaRatio is the side diffusion area ratio.
-
l_cumAreaRatio is the no-side cumulative area ratio.
-
l_cumDiffAreaRatio is the no-side cumulative diffusion area ratio.
-
l_cumSideAreaRatio is the side cumulative area ratio.
-
l_cumDiffSideAreaRatio is the side cumulative diffusion area ratio.

nil
|
The technology database does not exist or there are no electrical layer attributes or antenna models defined.
