Prerequisite
------------
Please make sure you have Innovus installed and the path to Innovus is added to your $PATH environment variable. To add a path to $PATH variable, add the following statement to your shell config file:

Assuming the path to Innovus is /path/to/innovus/bin

For bash/ksh, add the following line to .bashrc/.kshrc
export PATH=/path/to/innovus/bin:$PATH

For csh/tcsh, add the following line to .cshrc
setenv PATH /path/to/innovus/bin:$PATH

Usage
-----
./ispd18eval.sh -lef <path/to/input/LEF> -guide <path/to/input/guide> -def <path/to/solution/DEF>

Example
-------
./ispd18eval.sh -lef sample/ispd18_sample.input.lef -guide sample/ispd18_sample.input.guide -def sample/ispd18_sample.output.def

Required files
--------------
in benchmark directory (use benchmark "sample" as example):
ispd18_sample.input.lef - input LEF file
ispd18_sample.input.guide - input route guide file
ispd18_sample.output.def - output DEF file with routing solution

in evaluation directory:
ispd18eval.sh - evaluation script
ispd18eval - evaluation binary for score calculation
ispd18eval.w - weights for score calculation
ispd18eval.tcl - script for Innovus

Output files
------------
in the current directory (use benchmark "sample" as example):
score.rpt

Notes
