The spfd packageSPFD-based wire removal and replacement algorithm for logic optimization of combinational circuits mapped to FPGAs.By Balakrishna Kumthekar
This package implements wire removal and replacement based logic optimization for combinational circuits mapped to FPGAs. SPFDs (see the reference below) are used to represent flexibilities in the Boolean network. This package provides two commands: (1) spfd_pilo, a placement independent logic optimization technique. 2. spfd_pdlo: A combined logic and placement optimization technique. spfd_pdlo requires the package VPR. Please contact Balakrishna Kumthekar at kumtheka@avanticorp.com to obtaining a patch for VPR to work with VIS. S. Yamashita, H. Sawada, and A. Nagoya.
