Hello
i am new in dft calculation
i wanted to do a calculation of the relaxation of the structure , but when i write in the
cell_dofree='ibrav' an error msg appears
however if i change it by cell_dofree='all' it works.

can you help me to understand why it doesn't work with cell_dofree='ibrav'...

I am very new to DFT. When I tried to insert scan chain using insert_dft, dft_drc is showing the available scan FFs as ~23000 with 0 violations. But when I try to run dft_drc -coverage_estimate it gives an error:
Dead Socket.
Can u pls tell why this is coming.

How do we calculate the "Average Coverage" of different blocks?
Suppose we have three blocks like A,B and C having coverage respectively 89%, 92% and 91%.
So on which basis we can calculate coverage of all these blocks.

dump hierarchical statistics report ,that will give modular coverage and for depth you can give levels

I am getting c16 and S19 violations while doing dft_drc.Can anyone help me to resolve this?

It will be more convenient if you mention the issue instead of violation code.

C16 is like "Non scan cell unable to capture" and S19 is "non scan cell disturb"
