This file specifies the description of the C4 bump configurations file. The file is a csv as described below:
<x_coordinate>, <y_coordinate>, <octagonal_c4_bump_edge_length>, <voltage_value>
The x and y coordinate specify the center location of the voltage C4 bumps in micro meter.
The octagonal c4_edge_length specifies the edge length of the C4 to determine the pitch of the RDL layer in micrometer
Voltage_value specifies the value of voltage source at the C4 bump. In case there is a need to specify voltage drop in micrometer
