Mic array connectivity and pin assignment for FPGA

Hi there,

It looks like you have a great platform for realizing voice solutions across both SW and HW platforms. I am looking at the FPGA related files at https://github.com/matrix-io/matrix-creator-fpga/tree/master/creator_core to better evaluate the platform but saw a few items that don’t make sense. Specifically, the top level system.v and the constraint file do not appear to have the microphone array connected: 1) The UCF constraint file has reference to pdm_data but the assignments are commented out. 2) system.v has no reference to mic array connectivity.

Can you help clarify? Are there updated RTL and constraint files elsewhere? Or is there a schematic which we can use to do our own pin assignment?

Thanks.

Ying
