How do I avoid cells rotation in placement?

[OuDret]

I need a cell that does not rotate in both global and detailed placement. Is there any way to achieve it? I did not find any parameter.

Thanks

If it is a standard cell the LEF for the cell gives its symmetry.

Here it is

In LEF files symmetry definition is removed.
To run:
$ source counter_4Bbit.tcl

test_case.tar.gz

Thanks

what would you say is happening?

[maliberty]

I think we are not handling symmetry correctly in this case as it is unusual. I'll work on a fix next week as I'm OOO right now.

Thanks for the effort! ^^

Any news?

As this isn't a usual use case it has been lower priority. The simplest thing might be to just delete the rows that represent Y symmetry if you want to avoid such for your experiments.
