Hello everyone, I ran openlane flow for my design and got 140 antenna violations at the final. I am trying to reduce antenna violations in my design, and to do so I have changed DIODE_INSERTION_STRATEGY to 5 from 3. Then I have seen this error message and the flow failed. I think the reason is that, diode insertion strategy 3 does not use any diode in the layout, but strategy 5 does. It seems flow can not find diode libraries to place in the design. How can I fix this problem? Full log can be found in the log file.

I've found it's also worth trying different sizes and density settings.

The violations are bad, there are violations valued about 1500. Thus I want to change the diode insertion strategy. Generally diode insertion strategies 5 and 2 were much more effective than 3 in Open MPW2, hence I want to use them. But if there are alternative ways in Open MPW3, I may try them too.
