Is there a way to increase or decrease the number of decap cells placed by the openlane flow?

I had a similar question earlier. The only thing I found is to blacklist cells, but this did not help, it just used the other ones 😞

Thank you for the response! I'm working with Single Event Transients and wanted to increase or decrease the number of decap cells to check for the behavior of the circuit during a particle strike.

Why do you want to decrease them? OL choose to use the decap as the filler cell. You could use the standard filler cell instead.

That's a great idea, I will do that. I just wanted to analyze two different designs, one with less number of decap cells and the other with increased decap cells. In this way I'm trying to compare the efficiency of those designs during Single Event Transitions.

You could also script openroad to delete some fraction of the decaps using the db APIs if you need more points of comparison

Oh, sounds good! I will try that for sure.
