Can you share the command you used to test this?

Can you explain the changes in this file. Previously the code used data 0 and data 1. Now you are also using data 2 but not data 1.

The area report in Yosys 0.60 contains content similar to the following:

        +----------Local Count, excluding submodules.
        |        +-Local Area, excluding submodules.
        |        | 
      372  395.808   AND2_X1
       98   130.34   AND3_X1

That is, the real cell name is the third field, while the old code assumed that the cell name is the first field

Thanks for the explanation. Is that a change that was introduced in Yosys?

I've checked the commit history and I find it:
https://github.com/YosysHQ/yosys/commit/a0dde68487da600c569c0b61b684dc845fd5c554

Clearly the area report had been refactored, but it was NOT mentioned in the update log.
