7  Synopsis [SPFD-based wire removal and replacement algorithm for
8  logic optimization of combinational circuits mapped to FPGAs.]
9
10  Description [This package implements wire removal and replacement
11  based logic optimization for combinational circuits mapped to
12  FPGAs. SPFDs (see the reference below) are used to represent
13  flexibilities in the Boolean network. This package provides two
14  commands: (1) spfd_pilo, a placement independent logic optimization
15  technique.  2. spfd_pdlo: A combined logic and placement
16  optimization technique. spfd_pdlo requires the package
17  <a href="http://www.eecg.toronto.edu/~vaughn/vpr/vpr.html">VPR</a>.
18  Please contact Balakrishna Kumthekar at kumtheka@avanticorp.com to
19  obtaining a patch for VPR to work with VIS.
