Version 1.0 [Apr. 2004]
|
||
|
|
* Wirelength estimation based on the idea of ICCAD 04 paper.
|
||
|
|
|
||
|
|
Version 2.0 [Feb. 16, 2005]
|
||
|
|
* RSMT construction and Wirelength estimation based on the idea of ISPD
|
||
|
|
05 paper.
|
||
|
|
|
||
|
|
Version 2.1 [Mar. 18, 2005]
|
||
|
|
* The program flute-ckt and associated files are added to compute the
|
||
|
|
FLUTE wirelength for a circuit in bookshelf format.
|
||
|
|
|
||
|
|
Version 2.2 [Oct. 16, 2005]
|
||
|
|
* The net breaking technique is improved by incorporating the HPWL based
|
||
|
|
estimation in ICCAD 04 paper.
|
||
|
|
* The option to remove duplicated pins is added.
|
||
|
|
* The code is reorganized.
|
||
|
|
|
||
|
|
Version 2.3 [Sep. 23, 2006]
|
||
|
|
* PORT is renamed to POST (Potentially Optimal Steiner Tree)
|
||
|
|
* The function readLUT() is rewritten to significantly cut the POWV
|
||
|
|
and POST reading time.
|
||
|
|
|
||
|
|
Version 2.4 [Jan. 16, 2007]
|
||
|
|
* Internal parameters of flutes_wl_MD() and flutes_MD() are tuned to
|
||
|
|
improve runtime-quality tradeoff.
|
||
|
|
* The file size of POST9.dat is reduced by improved encoding.
|
||
|
|
* The function readLUT() is improved to speed up the reading of POST9.dat.
|
||
|
|
* Bookshelf files for ibm01 is included to demonstrate program flute-ckt.
|
||
|
|
|
||
|
|
Version 2.5 [Jun. 20, 2007]
|
||
|
|
* Local refinement technique is added to improve runtime-accuracy
|
||
|
|
tradeoff for high accuracy.
|
||
|
|
|
||
|
|
Version 3.0 [Apr. 10, 2008]
|
||
|
|
* Implemented the net breaking and merging ideas of VLSIDAT 08 paper to
|
||
|
|
achieve much better scalability and accuracy for high-degree nets.
|
||
|
|
|
||
|
|
Version 3.1 [Feb. 28, 2011]
|
||
|
|
* Functions in bookshelf_IO.c and memAlloc.c used by flute-ckt are
|
||
|
|
improved to speed up the reading of GSRC Bookshelf format circuits.
