    // 从指令存储器读取指令
    inst = pc[1] ? imem_ift.r_reply_bits.rdata[63:32] : imem_ift.r_reply_bits.rdata[31:0];
end

AI:

修正方法：

直接取 64 位存储器数据的低 32 位作为指令：

1
inst = imem_ift.r_reply_bits.rdata[31:0]; // 移除pc[1]的判断

实际：

1
inst = pc[2 ] ? imem_ift.r_reply_bits.rdata[63:32] : imem_ift.r_reply_bits.rdata[31:0];
