我在 Vivado HLS 中遇到问题我正在开发一个输入是 AXI-Stream 而输出也是 AXI-Stream 的 ipcore。在C Syntheseis 中没有问题，在C Simulation 中也运行良好。但是 RTL/Cosimulation 失败了。
我的顶级功能是这样的：
void CT(point_in SetA[2 * M], point_out Centers[M]){
#pragma HLS INTERFACE axis register both port=SetA
#pragma HLS INTERFACE axis register both port=Centers
...
}
这是我尝试运行 RTL/Cosimulation 时的控制台消息：
