Problem about guide and routing about dr-cu HOT 11 CLOSED

The router failed to connect the net and had to avoid open by some brute force using single-truck tree.
Could you check if the guides of every net are connected?
In case ispd18_test4, the IO pins are placed on Metal7 and Metal8, which potentially causes disconnected guides.

@creamycreamcream I have updated the code to report nets with detached pins.

@Rholais
we have try to compile your new source code but ended up some errors....
it is fine to compile with the old source code though
is there anything i need to install or how can i solve this problem?

from dr-cu.

Can you successfully compile commit 24660aa or bac7464?
You may try to remove the -static flag in Line 84 of src/CMakeLists.txt.

from dr-cu.

i removed the -static flag but also meet the same problem
and i have tried to changed the source code back it's still the same problem too

is it work fine while compiling on your server?

from dr-cu.

Yes, it compiles fine on our server.
Have you try both commits 24660aa and bac7464?

it is fine to compile with the old source code though

Which version of old source code did you try?

You may try to comment out Line 36 of src/CMakeLists.txt.

from dr-cu.

it works when i comment out Line 36 of src/CMakeLists.txt.
will the performance be difference with out this line?
or any other command can substitute this line?

from dr-cu.

Line 36 is about the linking of Boost.
Different versions and compilation options of Boost may affect runtime performance and result.

Do the nets routed by single-trunk trees have detached pins?

from dr-cu.

ok, i will only use new version for finding detached pins^^

yes, the problem have solved by linking detached pins together

i have another question.....
i use new version of DRCU to check our guide and find out there is no detached pins but there is an warning line appear

what situation may cause this problem
and also i would like to know the what situation may cause error line too

thanks for your kindly reply

from dr-cu.

As you can see from the error message, the guides of these four nets are detached.
Then Dr. CU tries to connect these guides by expansion.
Three of them succeeded after several iterations.
The last one net35341 failed.
Please make sure that the guides of a net are connected.

@creamycreamcream I will close the issue if there is no other problem regarding detached pins.
