CoralNPU is deployed on FPGA

[yelen103]

Dear Author, I'd like to ask you a question.
When I deployed coralnpu on fpga, I found that the interface file ddr4_stub.sv for ddr4 seemed incomplete. Moreover, some signals were missing in the pin constraint file pins_ddr_stub.xdc. Is this normal?

Thank you very much for your reply! Wish you a happy life！
