[Designutils 20-1009] Failed to set Constraints Type for fileset constrs_1 to UCF. UCF constraints are not supported in Vivado.Bit Generation Error[Project 1-227] Found UCF constraints while opening checkpoint. UCF constraint support in Vivado is deprecated in the 2012.2 public access release and is no longer available. Please migrate your UCF constraints to XDC-based constraints. Please refer to the Vivado Documentation for more information on migrating UCF constraints.
[Drc 23-20] Rule violation (NSTD-1) Unspecified I/O Standard - 2 out of 2 logical ports use I/O standard (IOSTANDARD) value 'DEFAULT', instead of a user assigned specific value. This may cause I/O contention or incompatibility with the board power or connectivity affecting performance, signal integrity or in extreme cases cause damage to the device or the components to which it is connected. To correct this violation, specify all I/O standards. This design will fail to generate a bitstream unless all logical ports have a user specified I/O standard value defined. To allow bitstream creation with unspecified I/O standard values (not recommended), use set_property SEVERITY {Warning} [get_drc_checks NSTD-1]. Problem ports: Button, Led.[Vivado 12-1345] Error(s) found during DRC. Bitgen not run.
