INFO: [DRC 23-27] Running DRC with 2 threads
WARNING: [DRC CFGBVS-1] Missing CFGBVS and CONFIG_VOLTAGE Design Properties: Neither the CFGBVS nor CONFIG_VOLTAGE voltage property is set in the current_design.  Configuration bank voltage select (CFGBVS) must be set to VCCO or GND, and CONFIG_VOLTAGE must be set to the correct configuration voltage, in order to determine the I/O voltage support for the pins in bank 0.  It is suggested to specify these either using the 'Edit Device Properties' function in the GUI or directly in the XDC file using the following syntax:

 set_property CFGBVS value1 [current_design]
 #where value1 is either VCCO or GND

 set_property CONFIG_VOLTAGE value2 [current_design]
 #where value2 is the voltage provided to configuration bank 0

Refer to the device configuration user guide for more information.
WARNING: [DRC PDRC-153] Gated clock check: Net seg2_OBUF[0] is a gated clock net sourced by a combinational pin seg2_OBUF[0]_inst_i_1/O, cell seg2_OBUF[0]_inst_i_1. This is not good design practice and will likely impact performance. For SLICE registers, for example, use the CE pin to control the loading of data.
