Design does not fit into Cyclone V on DE10-Nano #142

Greetings Dong,

I have been able to install your design and resolve build issues. I am building it against the de10 build project "de10_nano_sharedonly_hdmi". The build worked, but I ran out of resources.

The design requires 55K ALMs, but only contains 4191. I tried against the "de10_nano_sharedonly" -- without the HDMI, but this had the same issue.

I thought that your design would fit on the DE10-Nano. Is there something to adjust to reduce resource usage and help it fit?

Try to set the design with smaller VEC_SIZE and LANE_NUM. I have not tried the "hdmi" BSP yet.
