The following examples illustrate the instantiation of the BUFGMUX_VIRTEX4 module in
VHDL and Verilog.
//Example BUFGMUX module declaration
module BUFGMUX (O, I0, I1, S);
endmodule;
//Example BUFGMUX instantiation
BUFGMUX U_BUFGMUX (
.O(user_o),
.I0(user_i0),
.I1(user_i1),
.S0(user_s)
);
// Declaring constraints in Verilog
// synthesis attribute LOC of U_BUFGMUX is "BUFGCTRL_X#Y#";
// where # is valid integer locations of BUFGCTRL
INST "U_BUFGMUX" LOC = BUFGCTRL_X#Y#;
where # is valid integer locations of BUFGCTRL
