Question about the routing

[HeadRaising123]

Thank you very much for your open-source framework！Hello author, when I installed OpenPARF, the placement was able to run, but when using the router provided by the author, I found that router could not be done. After investigating the reason, I found that in line 22 of/OpenPARF/openparf/routing/router. py, import router_ cpp, it is not possible to parse the import "router_cpp". I couldn't find this package in the Python environment. Could you tell me where the problem is and then how to solve it?Thank you!

Thank you very much for your interest in OpenPARF. May I inquire if you have set the ENABLE_ROUTER option to disable when running the cmake command?

It would be better for debugging if you could provide a complete screenshot of the running command.

作者你好，非常感谢你们的开源布局布线框架！我也遇到了上述问题，即已经将ENABLE_ROUTER设置为ON了，也无法进行布线，输出No error，Segmentation fault (core dumped)。于是我重新安装了一遍OpenPARF，在cmake阶段遇到了如下问题。 这是我的cmake指令

cmake .. -DCMAKE_PREFIX_PATH=/home/gdut/anaconda3/envs/openparf -DPYTHON_EXECUTABLE=/home/gdut/anaconda3/envs/openparf/bin/python -DPython3_EXECUTABLE=/home/gdut/anaconda3/envs/openparf/bin/python -DCMAKE_INSTALL_PREFIX=/home/gdut/OpenPARF/install

If ENABLE_ROUTER has already been set to ON, the appropriate make command should be

cmake .. -DCMAKE_PREFIX_PATH=/home/gdut/anaconda3/envs/openparf -DPYTHON_EXECUTABLE=/home/gdut/anaconda3/envs/openparf/bin/python -DPython3_EXECUTABLE=/home/gdut/anaconda3/envs/openparf/bin/python -DCMAKE_INSTALL_PREFIX=/home/gdut/OpenPARF/install -DENABLE_ROUTER=1

Please try using this command.

Please try using this command.

作者你好，我使用了你所提供的cmake指令进行cmake，make，make install。以ISPD2016的benchmark为例，在FPGA01.json中，添加了"route_flag" : 1,。由于没有GPU，我将GPU选项设置为"gpu" : 0,。随后我在install的文件夹中执行该命令

python openparf.py --config unittest/regression/ispd2016/FPGA01.json 

最后输出的反馈如图所示。

[magic3007]

I'm very sorry, the compilation option should be set to -DENABLE_ROUTER=ON. Please use the following cmake command:

cmake .. -DCMAKE_PREFIX_PATH=/home/gdut/anaconda3/envs/openparf -DPYTHON_EXECUTABLE=/home/gdut/anaconda3/envs/openparf/bin/python -DPython3_EXECUTABLE=/home/gdut/anaconda3/envs/openparf/bin/python -DCMAKE_INSTALL_PREFIX=/home/gdut/OpenPARF/install -DENABLE_ROUTER=ON

作者你好，我使用了你提供的cmake指令进行cmake，make，make install。依然是以ISPD2016的benchmark为例，在FPGA01.json中，添加了"route_flag" : 1,。由于没有GPU，我将GPU选项设置为"gpu" : 0,。随后我在install的文件夹中执行命令

python openparf.py --config unittest/regression/ispd2016/FPGA01.json 

之后，出现了Segmentation fault (core dumped)的情况

Please confirm the following:

1. The version of G++ is 7.5.0. In our previous trials, errors have occurred when other versions were used.
2. Ensure that the XML file is accessible and readable.

We are fixing issues with the compiler, to make the program work in other compilation environments as well.

2. Ensure that the XML file is accessible and readable.

G++版本为7.5.0，XML文件也是可访问可读的。 依然是以ISPD2016的benchmark为例，在FPGA01.json中，添加了"route_flag" : 1,。由于没有GPU，我将GPU选项设置为"gpu" : 0,。 执行该命令:

python openparf.py --config unittest/regression/ispd2016/FPGA01.json

输出以下结果

Hi, could you please send us the results of the placement, i.e., results/FPGA01/FPGA01.pl for debugging? (My email address is jingmai at pku dot edu dot cn).
