我正在尝试使用vivado提供的分布式内存生成器来存储一些数据。但是ROM中的模拟总是"xxx"。
这是我的IP设置：我将其命名为temp。内存配置：深度=160，宽度=12，ROM。
端口配置：输入选项：已注册
这是我的测试台：
`timescale 1ns/1ps
module tb();
reg clk;
reg [6:0] a;
wire [11:0] out;
initial
begin
clk <= 0;
a <= 7'b0000000;
end
always #5 clk <= ~clk;
always #20 a <= a + 1;
temp u (.a(a), .clk(clk), .spo(out));
defparam u.inst.C_READ_MIF = "temp.mif";//initial ROM
endmodule
DEPTH = 160;
WIDTH = 12;
ADDRESS_RADIX = BIN;
DATA_RADIX = BIN;

这是我的模拟结果
我不知道为什么还剩下"000"。我应该如何使用ROM块？
很可能是初始化失败。检查模拟日志文件中是否有类似"无法打开…"的错误消息。
我之所以怀疑这是因为Vivado中的Xilinx文件位置非常非常恶劣。它们是相对于模拟目录的，模拟目录可以是Vivado项目目录中的4或5个目录。不仅如此，当我切换到新版本时，深度最近发生了变化，我不得不适应每个旧测试台上的每一条路径！(谢谢Xilinx！！(
这是一个模拟的例子，我必须在测试台(tb(中传递一个文件名：
.file_path ("../../../../../test_data/"),
.file_name ("testpattern_00.bin"),
我使用的目录结构是：
---+--tb
| |
| +-- test_bench.sv
|
+--test_data
| |
| +-- testpattern_00.bin
|
+--vivado_directory
|
+--vivado_project.xpr
