芯片的PPA追求是无止境的，因而在修时序的过程中我们需要对设计修复leakage，降低芯片的静态功耗。
以下分享一个典型的leakage脚本

set design 1
set version "V1"
set date [exec date +%m%d%H%M]
set working_directory ${design}_${version}_${date}##host option
set_host_options -num_process 4 -max_cores 16
report_host_usage
start_hosts

}remote_execute {write_changes -format text -output pt_text.tclwrite_changes -format ptsh -output pt_ptsh.tcl
}
##再使用脚本转化将ptsh文件变成innovus文件
