Hi @vinodsajjan

 

Check this AR:

You will get cpu time and elapsed time after each step of the design flow and their various phases.

@vinodsajjan,

 

Check the following forum thread which has the good TCL script to display the execution time:

Hope it helps.

Hi @vinodsajjan,

 

You can also try to write some TCL like - 

set systemTime [clock seconds]

or 

puts "The time is: [clock format $systemTime -format %H:%M:%S]"

in between the script for example – after synth_design and after say place_design, we would get the current time when this command is executed and the start of synth_design and implementation. Thus we can know how much time it took to run the process synth_design, though elapsed time is already given by tool.

You can also add something like puts "**<some_symbols>**" in between the command lines to highlight the time.

 

Thanks & Regards,
Prathik
