@Binoy B What is your operating frequency of design?
b
It wasnt designed to meet a specific frequency of operation. Rather it was an attempt to produce a functionally correct design. Is there any way to know the frequency of operation of the final design ?. I dont see any final summary report now.
v
try with CLOCK_PERIOD of 
20
Once flow pass with above settings then try to work on PPA
b
what is PPA?
v
power/performance/area
b
clock_period set to 20 didnt work. What will be the default value of clock period if the clock period is commented out in config.tcl?
v
Copy code
set ::env(CLOCK_PERIOD) "20"
Have you updated in this format?
can you share your 
config.tcl
?
b
yes I have updated the same way. Now I run the simulation after commenting out it.
config.tcl
v
remove 
#
for that line `31`and run again
b
actually i have run it without commenting it out . It resulted in flow failure.
so, will increase in clock _period help?
v
Copy code
#set ::env(CLOCK_PERIOD) "20"
If you ran with 
#
by default flow will use 
10ns
clock period
