Q&A
トップレベルのIOはbtn_0とled_rの2つだけですか?
クロックとかリセットとかありませんか?

前提
ここに質問の内容を詳しく書いてください。
ボタンを押すとLEDがひかって、ボタンを放すとLEDが消灯するプログラムを作っていますが、Generate Bitstreamを実行すると以下のエラーが出てしまいました。
発生している問題・エラーメッセージ
[DRC NSTD-1] Unspecified I/O Standard: 4 out of 4 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 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. Problem ports: q[1:0], i0, and i1.
[DRC UCIO-1] Unconstrained Logical Port: 4 out of 4 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. To allow bitstream creation 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.

試したこと
{ と [ の直前には半角スペースが必要とのことでそれを確認しましたが改善されませんでした。
補足情報（FW/ツールのバージョンなど）
Windows11
Vivado 2023.1
task11.vというファイルがあります！
module task11(
input btn_0,
output led_r
);
assign led_r = btn_0;
endmodule
