This doc describes the usage of the "code to compute ISPL values" before the clustering stage.

Reconfigurable Lab,
Electrical And Computer Engineering Department,
University of Arizona.
*******************************************************************************************************

INSTALLATION AND USAGE:

1. Download the ISPL.zip folder, unzip it.
2. The folder ISPL has the code and a sample input file.
3. In the destination folder, type 'make'
4. Type ./prog (sheel script) to run the code.
5. The output netlength files are written to the folder named 'outp'
*******************************************************************************************************

NOTE:

1. The 'tseng.blif' and 'tseng.act' are the sample input files.
2. The sample output netlength file is 'tseng.out'.
3. For using other benchmarks, change the 'star_var' variable's value in the 'prog' file.
*******************************************************************************************************

DESCRIPTION OF THE DIFFERENT FILES:

tseng.blif:Benchmark circuit to be clustered. This benchmark 
           circuit must have the .blif format.

tseng.net: Clustered netlist. The clustered circuit has the .net 
           format used required by the VPR FPGA place and route 
           tool.

tseng.act: Activity file. Contains a list of the node names and 
           corresponding switching activity. Can be generated using 
           the Activity estimator (Refer P-T-VPack and ACE activity estimator)

tseng.ac2: Output activity file required by the VPR FPGA place 
           and route tool.

tseng.fun: Output function file.

tseng.out: Output netlength file. This file has the predicted post-placement net length values.
