• —w500l2_1_C_0_0.txt - example of a point cloud file
• —file name format
• —w500l2: The 3D sampling window is height-adaptive and can accommodate 2 layers above and 2 layers below. 5 metal layers in maximum: Routing-Via-Routing-Via-Routing or Via-Routing-Via-Routing-Via. The 3D sampling window project to XOY-plane with an area sized $500 nm \times 500nm$.
• —1: the sample id when generation
• —C00: the position in the sample capacitance matrix

• —content format: point cloud file format that CloudCompare can read directly. | symbol | descriptions | | --- | --- | | $x$ | coordinate-x | | $y$ | coordinate-y | | $z$ | coordinate-z | | $nx$ | component-x of normal vector | | $ny$ | component-y of normal vector | | $nz$ | component-z of normal vector | | $\varepsilonr$ | the dielectric channel, relative permittivity | | class | a point belongs to a class that relates to its generation | | $\Phi$ | the selecting channel |
• —line 1 : 432.715, 171.114, 0.5879, 1, 0, 0, 4.06, 1, 0 A point with coordinates (432.715, 171.114, 0.5879) in layout. This point is generated on the surface of a region whose local normal vector is (1, 0, 0). This local region is full of dielectric with a relative permittivity of 4.06, except the region inner the conductor. The id of this region equals 1. The selecting channel value of this point is 0, such as non-target environment conductors. The details of the setting are related to the Gauss Law-based Point Cloud feature.
