SDx 2017.2报错的解决方法：ERROR: [IMPL 213-28] Failed to generate IP.

尝试使用zc706运行example中的matrix multiplication and addition例程，尝试SDx编译，发现报错：

Loaded SDSoC Platform Tcl Library
source run_ippack.tcl -notrace
ERROR: [IMPL 213-28] Failed to generate IP.
command 'ap_source' returned error code
    while executing
"source D:/Xilinx/MyProjectsSDx/test/Debug/_sds/vhls/madd_run.tcl"
    invoked from within
"hls::main D:/Xilinx/MyProjectsSDx/test/Debug/_sds/vhls/madd_run.tcl"
    ("uplevel" body line 1)
    invoked from within
"uplevel 1 hls::main {*}$args"
    (procedure "hls_proc" line 5)
    invoked from within
"hls_proc $argv"
INFO: [HLS 200-112] Total elapsed time: 22.163 seconds; peak allocated memory: 73.262 MB.

 

在对madd函数通过vivado编译时也报错：

Loaded SDSoC Platform Tcl Library
source run_ippack.tcl -notrace
ERROR: [IMPL 213-28] Failed to generate IP.
command 'ap_source' returned error code
    while executing

    ("uplevel" body line 1)
    invoked from within
"uplevel 1 hls::main {*}$args"
    (procedure "hls_proc" line 5)
    invoked from within

Finished export RTL.

 

这两个应该是同一个错误

有人描述解决办法是：把RESOURCE改成INTERFACE，就可以了，综合时精简了引脚。

我表示看不懂。。。。这里有一个类似说法：

I guess you have used HLS Resource directive to set an AXI4 stream interface. Have you set the port map also when you set it:
 Example:
#pragma HLS resource core=AXI4Stream variable=data_i metadata="-bus_bundle
AXI4Stream_S" port_map={{data_i_data TDATA} {data_i_strb TSTRB}}

 

解决办法是：这里的描述跟我的问题不一致啊，怎么恰好能解决呢，捂脸

Solution
While this update for Windows 10 is not officially supported with Vivado 2017.3, the following work-around is available:
Navigate to (Vivado Installed Directory)2017.3inunwrappedwin64.o
Backup 'vivado.exe' by renaming it to 'vivado.exe.backup'
Copy 'vivado-vg.exe' and paste it into the same folder.
Rename 'vivado-vg - Copy.exe' to 'vivado.exe'
After the above steps are followed, Vivado will launch normally.

 

可能是更改了vivado的一个配置，对win10的兼容性才变好了？

修改之后vivado HLS已经可以正常编译了，SDx也没有报错了。
