I'm trying to get Pmod AD1 working with Cora-Z7-10. However, Generate Bitstream fails with the error code below. When I checked the forum, it seems that the cause is that the IP core update has stopped.Is there a sample program that uses GPIO instead? Also, is there any other way to deal with it? Thank you.
[DRC NSTD-1] Unspecified I/O Standard: 8 out of 138 logical ports use I/O standard (IOSTANDARD) value 'DEFAULT', instead of a user assigned specific value. 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 this command: set_property SEVERITY {Warning} [get_drc_checks NSTD-1]. NOTE: When using the Vivado Runs infrastructure (e.g. launch_runs Tcl command), add this command to a .tcl file and add that file as a pre-hook for write_bitstream step for the implementation run. _io, and ja_pin9_io.
[DRC UCIO-1] Unconstrained Logical Port: 8 out of 138 logical ports have no user assigned specific location constraint (LOC). 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 pin locations. This design will fail to generate a bitstream unless all logical ports have a user specified site LOC constraint defined. with unspecified pin locations (not recommended), use this command: set_property SEVERITY {Warning} [get_drc_checks UCIO-1]. NOTE: When using the Vivado Runs infrastructure (e.g. launch_runs Tcl command), add this command to a .tcl file and add that file as a pre-hook for write_bitstream step for the implementation run. Problem ports: ja_pin10_io, ja_pin1_io, ja_pin2_io, ja_pin3_io, ja_pin4_io, ja_pin7_io, ja_pin8_io, and ja_pin9_io.
