【FPGA】xilinx IOBUF的用法
// IOBUF: Single-ended Bi-directional Buffer // All devices // Xilinx HDL Language Template, version 2017.2 IOBUF #( .DRIVE(12), // Specify the output drive strength .IBUF_LOW_PWR("TRUE"), // Low Power - "TRUE", High Performance = "FALSE" .IOSTANDARD("DEFAULT"), // Specify the I/O standard .SLEW("SLOW") // Specify the output slew rate ) IOBUF_inst ( .O(O), // Buffer output .IO(IO), // Buffer inout port (connect directly to top-level port) .I(I), // Buffer input .T(T) // 3-state enable input, high=input, low=output ); IOBUF #( .DRIVE(12), // Specify the output drive strength .IBUF_LOW_PWR("TRUE"), // Low Power - "TRUE", High Performance = "FALSE" .IOSTANDARD("DEFAULT"), // Specify the I/O standard .SLEW("SLOW") // Specify the output slew rate ) IOBUF_inst_io0 ( .O(s_din[0]), // IO_pad输入。管脚经过IBUF缓冲输出到内部信号 .IO(spi_io[0]), // pad接口/管脚 .I(s_dout[0]), // 输出到IO_pad。内部信号经过OBUF缓冲到管脚 .T(x_writ_read) // 当IO_pad需要输入的时候,使能OBUF使其输出高组态。 );
