how can i get delay report from design compiler

[ranjbar_7]

hi

in the scipt that we wrote for design compiler what we should write for geting delay report?

i have written this script what should I add to it?

--------------------------------------------------------
set my_files second.vhd
set my_toplevel project1
set my_clock_pin CLK
set my_clk_freq_MHz 100
set my_input_delay_ns 0
set my_output_delay_ns 0
set link_library ./osu025_stdcells.db
set target_library ./osu025_stdcells.db
define_design_lib WORK -path ./WORK
set_ultra_optimization true
set_ultra_optimization -force
analyze -f verilog $my_files
elaborate $my_toplevel
current_design $my_toplevel
link
uniquify
set my_period [expr 1000 / $my_clk_freq_MHz]
set find_clock [ find port [list $my_clock_pin] ]
if { $find_clock !=

• } {
  set clk_name $my_clock_pin
  create_clock -period $my_period $clk_name
  } else {
  set clk_name vclk
  create_clock -period $my_period -name $clk_name
  }
  set_driving_cell -lib_cell INVX8 [all_inputs]
  set_input_delay $my_input_delay_ns [all_inputs]
  set_output_delay $my_output_delay_ns [all_outputs]
  compile -ungroup_all -map_effort medium
  compile -incremental_mapping -map_effort medium
  check_design
  report_timing
  report_timing -delay min
  report_timing -delay max
  write -f ddc -o ./Reports/myddc.ddc
  write -f verilog -o ./Reports/netlist_verilog.v
  write -f vhdl -o ./Reports/netlist_vhdl.vhdl
  write_sdf ./Reports/Stndrd_Dly_Frmt.sdf
  write_parasitics -o ./Reports/C_R_delays.spef
  write_sdc ./Reports/sdc.sdc

 

[matter]

You have already added the commands to get delay reports in your script.

report_timing
report_timing -delay min
report_timing -delay max

The above commands will give you the timing report. The report_delay command, by default reports max_delay. So report_timing will give the same output as report_timing -delay max. So you can remove one of the redundant commands.

Also I suggest you to redirect the output, so that you can review them later on easily, otherwise you will have you search in the log files.
i.e.
report_timing -delay max > max_tim.rpt
report_timing -delay min > min_tim.rpt
