谁能告诉我VHDL结构体定义中这里面的ATTRIBUTE是什么,代表什么含义?我真的找不出这是什么类型数据。
ATTRIBUTE syn_romstyle: string;
ATTRIBUTE syn_romstyle OF el2if_xpdsch_ldpc_lut_rom : CONSTANT IS "block_rom";
ATTRIBUTE syn_romstyle OF el2if_xpdsch_seg_lut1_rom : CONSTANT IS "block_rom";
ATTRIBUTE syn_romstyle OF el2if_xpdsch_seg_lut2_rom : CONSTANT IS "block_rom";
谢谢!
