routing pin error

[MeloLuo]

In some cases, such as case2, the pins cannot be found in the third iteration of post-processing. In some eight-layer designs, problems with memory exceptions can occur.

Thank you very much for your reply. Command line input I follow the file bin/benchmark.sh. I am running a2,a3,a5,n1,n3,n4,n5 and the program has an error: NthuRoute: src/router/MM_mazeroute.cpp:211: void NTHUR::Multisource_multisink_mazeroute::setup_pqueue():  Assertion `pin1_v ! = nullptr' failed. When I ran b3,b4,n7, the program reported malloc(): memory corruption. Here are some pictures to illustrate the problem.

I have encountered the same problem as MeloLuo. Is there a solution to this bug?

Hi, I did not investigate for this bug. I do not know how long it would take to correct this bug. Your contribution is welcome.

Thank you very much for your reply! I think it might be an issue with the running platform or the gcc compiler version. Anyway, I am a researcher working on VLSI physical design, and my current research involves analyzing and comparing routing results from various benchmarks. I am particularly interested in the routing results of NTURouter on the ISPD 2008 Global Routing Contest benchmarks.

I noticed that while these results are mentioned to be available through your website (https://www.cs.nthu.edu.tw/~tcwang/nthuroute/), the download link appears to be no longer active. I would be very grateful if you could share these routing results with me ([email protected]) directly.

Your assistance in this matter would be greatly appreciated and would significantly help advance my research.

Thank you very much for your time and consideration.

Hi,

It is much more probable that there is an error of logic in the code, and gcc and runtime are fine. I do not own the webpage of Ting-Chi Wang. You would have to send him an email. I do not have access to these results myself. By the way, the results are pretty old. Have a nice day

Thank you for your prompt reply! I'd like to ask if Professor Ting-Chi Wang's email address is [email protected]? This is the email address I found when searching on Google Scholar, but I'm not sure if he's still using this email. If you have any information about this, please let me know. I would be very grateful!
