Sample

Sample CPU

简单说明

该CPU现在可以执行ori lui addiu beq这四种指令，但并没有完成数据相关，请自行添加相关数据通路。
之后出现的问题可直接在群里提问，然后会被记录在这里形成Q&A。
请使用Github进行版本管理，便于验收时检查。如果因为误操作导致一些记录被抹掉或者需要更换仓库请及时通知助教。

使用方法

在服务器上准备好文件夹，导入SampleCPU内的所有.v .vh文件
启动路径nscscc_group/func_test_v0.01/soc_sram_func/run_vivado/mycpu_prj1下的mycpu.xpr项目
在Vivado中添加源文件，把SampleCPU内的所有.v .vh文件都导入（包括lib文件夹下）
点击Simulation进行仿真，第一次仿真时会对项目使用的ip核进行综合，可能需要等待10分钟左右
点击▶进行仿真，如果波形图卡住可在下方的控制台看到提示信息，这是龙芯实验平台提供的比对机制，会告诉你当前在哪条指令出现错误，根据汇编指令和你学的流水线知识进行debug
运行的汇编指令可在nscscc_group/func_test_v0.01/soft/func/obj/test.s 该文件中查找。VSCode打开搜索pc值即可，9fc开头的pc值在汇编文件中以bfc查找就可以。
指令集文件可在doc文件夹的A03中查看。
其他相关问题基本都可在doc文件夹或参考书籍中找到答案（例如A09包含了对于X、Z信号的解释）。
欢迎留言，看到会回复，另外请注意Q&A的更新。

指令添加方法

阅读指令集文件，查看该指令会进行哪些操作
对于IF段，P64之前注意跳转指令即可
对于ID段
- 需要在该级进行指令译码
- 从寄存器中读取需要的数据
- 完成数据相关处理
- 生成发给EX段的控制信号
对于EX段
- alu模块已经提供，基本通过给alu提供控制信号就可以完成逻辑和算术运算
- 对于需要访存的指令在此段发出访存请求
对于MEM段
- 接收并处理访存的结果，并选择写回结果
- 对于需要访存的指令在此段接收访存结果
对于WB段
- 和IF段类似，暂时没有需要改动的东西

💡 Debug建议

😕不要啥问题都来问助教，尤其是让助教帮你debug，在问之前先看看文档，问问同学，大部分bug都能解决

查看console（控制台）中的trace比对机制的提示，记下提示的PC值，并猜测可能发生的错误
打开test.s文件，使用提示的PC值进行查找，查看对应的指令是什么，判断是否~~添加该指令~~完整地实现了该指令
如果没~~添加指令~~完整实现，则前往 A03文件阅读指令集，学习对应指令的执行要求
如果指令已经被添加，则到波形图中去检查运算结果错误原因
当找到错误波形图时，请逐步添加其源头信号，直至发现引入错误的源信号，并改正
修改后可能会出现新的错误，此时请重复步骤5

可能会遇到波形图卡住或mycpu_tb.v一直仿真停不下来的情况，已知有两种情况：

// 代码因为逻辑环路导致某个寄存器的值在一个时钟周期内反复横跳无法仿真
// 下面是个例子，当然你们写出的环路可能会复杂得多，debug时抓住reg去找问题
reg[31:0] pc_r;
wire flag;
always @(posedge clk)
begin
    if(flag)
    begin
        pc_r <= 32'hbfbf_fffc;
    end
    else begin
        pc_r <= 32'b0;
    end
end
assign flag = |pc_r ? 1'b0 : 1'b1; 

// 以下是testbench中的比对逻辑，一些奇奇怪怪的写回情况会导致仿真程序一直运行下去，大家debug时要考虑清楚
//compare result in rsing edge 
reg debug_wb_err;
always @(posedge soc_clk)
begin
    #2;
    if(!resetn)
    begin
        debug_wb_err <= 1'b0;
    end
    else if(|debug_wb_rf_wen && debug_wb_rf_wnum!=5'd0 && !debug_end && `CONFREG_OPEN_TRACE)// 只有运行结果写回寄存器堆且不是0号寄存器的指令才会进行比对
    begin
        if (  (debug_wb_pc!==ref_wb_pc) || (debug_wb_rf_wnum!==ref_wb_rf_wnum)
            ||(debug_wb_rf_wdata_v!==ref_wb_rf_wdata_v) )// 如果三项中有是全X(即未赋值)，那么它将可以代表任意值并通过测试
        begin
            $display("--------------------------------------------------------------");
            $display("[%t] Error!!!",$time);
            $display("    reference: PC = 0x%8h, wb_rf_wnum = 0x%2h, wb_rf_wdata = 0x%8h",
                      ref_wb_pc, ref_wb_rf_wnum, ref_wb_rf_wdata_v);
            $display("    mycpu    : PC = 0x%8h, wb_rf_wnum = 0x%2h, wb_rf_wdata = 0x%8h",
                      debug_wb_pc, debug_wb_rf_wnum, debug_wb_rf_wdata_v);
            $display("--------------------------------------------------------------");
            debug_wb_err <= 1'b1;
            #40;
            $finish;
        end
    end
end

如果添加新的指令需要改动流水线结构可以参考《自己动手做CPU》或者问助教。PS：这本书原理说的还算明白，代码真别抄了，always写出来的组合逻辑你们把握不住
如果助教也不知道你们错在哪了，请陪他一块反思

💭 Q&A

Q：关于如何检查工作量？

A：建议各位同学每天写完代码都push到Github上，到最后代码量一目了然，工作进度也很清楚。
（如果一定要最后几天扎堆提交，我也愿意听你解释，当然分数好不好看就不知道了）
Q：拿到这个模板我应该如何入手？

A：群里有《自己动手写CPU》这本书的PDF，如果对流水线、旁路、数据相关之类的内容还没有概念，可以先看看这本书。在掌握每章的内容后把该章节的内容写到自己的CPU里去。(请不要妄图直接使用这本书里的源码，最后验收的时候会检查代码，代码长什么样我还是一清二楚的。对于别的学校的代码，如果你去观摩学习，然后把里面的好东西拿来用，那我非常支持。如果你直接把别人的代码copy过来用，那看一下代码风格，问几个问题基本就露馅了，没意思的)
Q：服务器上压缩文件？

A：可以使用tar命令，或用apt命令安装zip / unzip。压缩包下载到本地解压即可。
Q：关于9fc地址的说明

A： 9fc是经过mmu.v模块映射的虚地址段，在test.s中按照bfc开头查找即可。但是在仿真时要严格遵守比对机制，二者并不等价。
Q：有的指令在A03里找不到？

A：指令均未超出范围，test.s中针对一些指令的特殊情况使用了别名，同学们按照pc后记录的指令内容翻译成二进制去比对即可。

Q：关于访存指令的说明

A：因为现在的存储器用的一般都是字节编址，所以data_sram_wen这个写使能信号是4位，每一位控制一个字节的数据。故sw指令对应4'b1111，lw指令对应4'b0000。

sb指令一次只写入一个字节，所以可能是4'b0001 4'b0010 4'b0100 4'b1000这四种情况，具体选择那种，根据写地址的最低两位addr[1:0]判断。00对应最低位字节(data_sram_wen应为4'b0001)；11对应最高位字节(data_sram_wen应为4'b1000)。sh指令类似于sb指令，但其只有两种情况，地址最低两位为00对应低位两个字节(data_sram_wen应为4'b0011)；地址最低两位为10时对应高位两个字节(data_sram_wen应为4'b1100)。

load类指令与store类指令略有不同，由于这个存储器只配置了片选(4byte)使能和字节写使能，所以读取的时候一律是先读回CPU(此时不区分是哪个load指令)，在MEM段再进行更细分的操作。load类指令的字节选择方法和store类相同。

// 这里给出一个美观的写法供大家参考，要弄懂原理，不要直接抄

            2'b01:begin out = 4'b0010; end
            2'b10:begin out = 4'b0100; end
            2'b11:begin out = 4'b1000; end
            default:begin
                out = 4'b0000;

                    inst_lw     ? w_data : 32'b0;

Q：要加多少指令才能通过测试点？

A：测试点和指令没有严格的对应关系，同学们可以在test.s中查找n1_、n32_等来分析测试点内容。但是有一些结构上的要求需要同学们仔细思考，不一定在哪个测试点就可能遇到，例如forwarding解决数据相关、多周期指令插入stall。

// 为了降低难度，给大家一份控制台的输出作参考（由于各组实现方式不同，通过检查点的运行时间可能会有些许差别）
