When I run make synthesis. It gets errors

'bitwidth' attribute requires integer constant between 1 and 4096 inclusive.
I changed all the size in Cmake but it's not working. My enviroment is Alveo U280, Vitis 2021.2.
Can you help me to solve the problem? Thanks.

This was a bug with an update to ConstLog2 in hlslib and has been fixed in master now. However, it seems like the project currently doesn't build with II=1 in the 2021.2, so I need to look into this.
