这是我的约束文件 关于编译出来的NET "fpga_0_rst_1_sys_rst_pin_IBUF"我根本没有啊，工程中我都没添加这样的IBUF。。。。
这是 cpu类化文件：
// Instantiate the module
(* BOX_TYPE = "user_black_box" *)
cpu_led instance_name (
.fpga_0_RS232_DCE_RX_pin(fpga_0_RS232_DCE_RX_pin),
.fpga_0_RS232_DCE_TX_pin(fpga_0_RS232_DCE_TX_pin),
.fpga_0_LEDs_8Bit_GPIO_IO_O_pin(fpga_0_LEDs_8Bit_GPIO_IO_O_pin),
.fpga_0_clk_1_sys_clk_pin(fpga_0_clk_1_sys_clk_pin),
.fpga_0_rst_1_sys_rst_pin(fpga_0_rst_1_sys_rst_pin)
);
这是我的top实现：
