4.1.1.1. Example of Converting I/O Buffer

In this example, the clk, a, and b inputs are global signals, and the a and b inputs use the IBUFG I/O Standard.

Converting BUFG, IBUFG, and OBUF in Verilog HDL.

Original Verilog HDL Code in the Vivado* Software 

module Top (a, b, c, clk);
 input a, b, clk;
 output c;
 reg c_buf;
 wire a_buf, b_buf, clk_buf;
 BUFG inst1 (.O (clk_buf), .I (clk));
 IBUFG #("FALSE", "SSTL12") inst2 (.O (a_buf), .I (a));
 IBUFG #("FALSE", "SSTL18_I") inst3 (.O (b_buf), .I (b));
 OBUF inst4 (.O (c), .I (c_buf));
 always @ (posedge clk_buf) c_buf <= a_buf & b_buf;
endmodule

To set the ports with specific assignments in the Intel® Quartus® Prime Pro Edition software, use the Assignment Editor.

Figure 11. Global Signal and I/O Standard Assignments Using the Assignment Editor

In the figure, inputs a, b, and clk are assigned as global signals, with clk as the global clock. Input ports a and b are assigned with specific I/O standards, while other ports are automatically assigned with the device-specific default I/O standard.
