关于ISE中的逻辑模块产生中断信号到microblaze中的问题

你好，我想请教下，你有没有做过用ISE里面的逻辑产生中断到microblaze呢?我现在试着用BRAM的一个端口连接microblaze，另外一个端口连接ISE里面的逻辑模块，然后将ISE中BRAM写入数据，将数据输出线连接到microblaze中的中断控制器，写入的数据位0、1、0，中断设置的为上升沿触发，我觉得逻辑上是可以实现的，结果生成的bitstream导入到SDK后，发现在指定的地址写入数据无法触发中断，不知道这个该怎么办?
如果知道的话麻烦帮我看下
我在ISE中的逻辑模块的代码如下所示：
module cpu1_intr(
sysclk,
sysrst,
bram_block_0_BRAM_EN_B_pin,
bram_block_0_BRAM_WEN_B_pin,
bram_block_0_BRAM_Addr_B_pin,
bram_block_0_BRAM_Din_B_pin,
bram_block_0_BRAM_Dout_B_pin,
CPU1_TO_CPU2_INTR
    );
input sysclk;
input sysrst;
input bram_block_0_BRAM_EN_B_pin;
input bram_block_0_BRAM_WEN_B_pin;
input [31:0] bram_block_0_BRAM_Addr_B_pin;
output [31:0] bram_block_0_BRAM_Din_B_pin;
input [31:0] bram_block_0_BRAM_Dout_B_pin;
output CPU1_TO_CPU2_INTR;
       
assign CPU1_TO_CPU2_INTR_cs = bram_block_0_BRAM_EN_B_pin & (bram_block_0_BRAM_Addr_B_pin[31:0] == 32'h0x10000300);//6020H
reg  CPU1_TO_CPU2_INTR;
always @(posedge sysclk or posedge sysrst)
if (sysrst) CPU1_TO_CPU2_INTR <= #1 1'b0;
else if(CPU1_TO_CPU2_INTR_cs&bram_block_0_BRAM_WEN_B_pin) CPU1_TO_CPU2_INTR <= #1 bram_block_0_BRAM_Dout_B_pin[0];
assign bram_block_0_BRAM_Din_B_pin = CPU1_TO_CPU2_INTR_cs ? {31'b0,CPU1_TO_CPU2_INTR} : 32'hzzzzzzzz;
endmodule

小编再帮我看看我这个有啥问题?谢谢了啊

有没有了解的人呢?

小编是把BRAM的B口接ISE,A口接microblaze的bram control上么?

A口接了一个BRAM控制器，这个是在XPS里面连接的

有没有人了解这个呢?ISE产生中断到microblaze

没有人的啊

你好，你的问题解决了吗?我也遇到了同样的问题。
