insertion of buffers to fix max cap and max trans DRV violation

[sg0786]

Hello I am using cadence encounter and need to fix drv violations of max cap and max tran after placement stage. one way is to insert a buffer. What is the command to do that?
thanks in advance

optdesign -drv, will fix the drv for the setup analysis view.

optdesign -drv, will fix the drv for the setup analysis view.

I tried this command but still getting max cap of -0.1 and max trans of -0.01.

Is there any commend (in encounter ) to insert buffer manually at a particular pin ?

you could increased the drv margin with:

setOptMode -drcMargin 0.150 ;# add 15% DRV margin to the 20% extra margin already added by default by the tool.
setOptMode -fixFanoutLoad    true      ; # default false: Fixes max fanout violations to reduce runtime
