Documentation for Wol consists of a long manual, written by Mass Sivilotti, in Postscript. These manuals are basically untouched from the pre-Unix version of Wol, and are in need of updating and HTML conversion. The manual covers other tools, such as Netcmp, Wolcomp, and Mosis, as well as Wol.
To help understand how to use Wolcomp and Wol in a real chip design, with the current version of the tools, serious users will want to check out the examples package, which contains a VLSI chip design done using Wol and Wolcomp. Press here for information on picking up the examples package.
