techSetLayerAnalysisAttribute(
d_techfileID
tx_layer
t_attributeName
g_attributeValue
) 
=> t / nil

Sets a specified attribute value for a layer with a layer function that supports attribute analysis.

d_techfileID	The database identifier of the technology database.
tx_layer	The layer name or number.
t_attributeName	The name of the attribute. The valid attribute names are: `materialName`: The name of the material. `thickness`: The thickness of the layer in microns. `conductivity`: The conductivity of the layer in siemens/meter. `permittivity`: The dielectric constant of the layer. `lossTangent`: The loss tangent of the layer.
g_attributeValue	The value of the attribute. It can be String or Double.

`t`	The specified attribute has been set for the layer.
`nil`	The attribute value was not set. The layer does not have a function that supports layer analysis attributes, or it does not exist in the technology database.

techSetLayerAnalysisAttribute(tech "Metal1" "materialName" "Copper")
=> 0.9

Sets Copper as the value of the materialName attribute for the Metal1 layer.
