Also I found this message in openlane during my inspection of the user project example.

Warning: Some pins weren't matched by the config file
Those are: ['user_clk', 'irq[0]', 'irq[1]', 'irq[2]']
Assigning random sides to the above pins

I thought that the pins position is something that we can not change. This pins need to be defined by us?

@Ivan Rodriguez The pin positions for the user project wrapper itself have to be fixed. For any macro inside the wrapper, you can choose any pin position you want. If these warnings are flagged in the user_proj_example, then it is okay. They are flagged because the

pin_order.cfg

file doesn't specify an edge for them

ok perfect, thanks
