1.eco net 

## eco just select net 
setNanoRouteMode -routeSelectedNetOnly true
selectNet {inst_adrctl_master_delay/inst_mstr_dly_macro/mstr_qtr_delay_sel[0]}
ecoRoute -target

2. generate  def and gds  , db 

set topcell [dbget top.name]
# def out 
defOut -scanChain -netlist -placement -routing $file_dir/$topcell.def.gz
##save db.date
saveDesign -verilog fix_net

#gds

set GDS_LIST ""
lappend GDS_LIST /process/tsmcN12/data/stdcell/tsmc/n12ffcll/TSMC/tcbn12ffcllbwp16p90cpd_100d/gds/tcbn12ffcllbwp16p90cpd.gds

setStreamOutMode -virtualConnection false
streamOut   -units 1000 \

3. generate dummy and merge dummy to gds

4.run qrc to generate spef 

5.run mmmc analysis timing
