Hello, I got very strange behavior of the toolchain. What happens is the final GDS show some unconnected inputs. The design itself works at the functional level however I have got two pins "mclk" and "pdm_data_i" unconnected. Revising the post synthesis GL netlist I found that thos signals appear on the netlist however do not connect to anything. Anybody willing to help ?
