Stable Distribution (Magic 8.1) Source

In 2017, Version 8.1 has finally been declared stable enough to supplant version 8.0 as the new stable distribution. As with version 8.0 before it, any bugs found will be fixed. However, further development and major code changes will be made to the development distribution version 8.2. The first revision to be called stable is magic-8.1.158.

The PLA tools package has its own libmpack.a archive, corresponding to magic 7.1.7. It will link statically to this file when compiling. Check the value of install destination CAD_HOME in the Makefile for mpla and mquilt before installing. This distribution has been successfully compiled under Linux, but compilation/installation is not guaranteed. Please contact me if you have any difficulties, or for any questions regarding the distribution. Note that magic versions 7.2 and 7.3 do not contain the mpack subdirectory and therefore do not compile an mpack library as needed by the PLA tools. Hopefully this will be rectified in the near future. If you encounter problems when linking to the "libmpack.a" library, you will probably need to download and compile magic 7.1.7 first, then copy the file "libmpack.a" into the platools "lib" directory, overwriting the existing one. This ensures that calls made to system routines in the library archive will be recognized by your linker. One problem has already been reported with the call to routine "__ctype_b", a macro expansion from routines such as "isspace()", when compiled under gcc 2.95 ("libmpack.a" in this platools distribution was compiled under gcc 2.96).

Thanks very much to Dr. Poras Balsara of the University of Texas at Dallas for providing the source distribution of PLA tools.

Programs espresso, meg, and peg are independent of magic. Programs mpla and mquilt use magic internal routines from the library libmpack.a but are standalone programs (like ext2sim and ext2spice).

Thanks to Dietmar Lippold for updates to espresso for compilation under gcc-4.

Thanks to Dwayne Jackson for providing the source distribution of Lager 5.1, originally obtained from Bob Reese at Mississippi State University. The stochastic descent algorithm channel router is one that I wrote at Johns Hopkins to help with constructing standard cell libraries, and intern Jennifer Roberts helped with extending it to a general-purpose standard cell router. It has quite a few limitations (e.g., 2-metal layers, and handles only two rows/one channel) and needs a lot of work, but it's usable, and it's the only channel router I've seen based on something other than Steiner trees and simulated annealing.

TimberWolf is modified from the last open source version for which source code was made publicly available, which is version 6.0. The current commercial version of TimberWolf can be found at iTools. Version 6.1 represented my port of the 6.0 source code to Linux. Version 6.2 has some further modifications that will allow compiling on gcc up to and including version 3.4 (haven't tried 4.0 yet). In addition, version 6.2 includes TimberWolfDR (detailed router, otherwise known as "mighty" from the OctTools distribution). Plus, since I was recently testing the use of TimberWolf for producing routed layout, I also included "yacr" from OctTools 5.2. Version 6.3 is an attempt to make TimberWolf 64-bit clean, and corrects at least one fatal memory allocation error.

See Digital Flow for various format translation scripts useful in conjunction with TimberWolf for a digital flow.
