In 4.0 how to generate flute LUT

[kouyichi]

in dreamplace/ops/timing/src/timing_cpp.cpp line139-144

using Point2i = ::DreamPlace::Point<int>; dreamplacePrint(kINFO, "launch rc tree construction...\n"); flute::readLUT( "thirdparty/flute/lut.ICCAD2015/POWV9.dat", "thirdparty/flute/lut.ICCAD2015/POST9.dat"); auto beg = std::chrono::steady_clock::now();
flute use a look up table that already made. If I want to use the 4.0 in something out of iccad2015, how can I generate the look up table?

They come from the source code of flute. It should also work in other benchmarks.

Sorry, I'm not very familiar with the flute code. I just saw there is a readLUT and not a writeLUT function; where can I find the function that generates a LUT from some file?

You'd better read the original FLUTE paper to get the idea how it works before looking into the code. Its LUT is quite general and does not requires re-generation for different designs.&nbsp; https://ieeexplore.ieee.org/document/4358497 Original From:"kouyichi"< ***@***.*** &gt;; Date:2023/7/13 1:25 To:"limbo018/DREAMPlace"< ***@***.*** &gt;; CC:"Subscribed"< ***@***.*** &gt;; Subject:Re: [limbo018/DREAMPlace] In 4.0 how to generate flute LUT (Issue#142) They come from the source code of flute.
