Description
Warning: [200-937] Multiple
loop unroll directives in one loop, use the first one and ignore the
rest.
This message reports that the code is violating loop unrolling
optimization rules.Explanation
The tool is ignoring multiple unrolling optimization constraints. This happens when the constraints defined are in the same scope, as shown below.
for(int i=0;i<var;i++)
{
#pragma HLS unroll
...
...
#pragma HLS unroll factor =8
...
...
}
Solution
Review the multiple conflicting pragmas in the same scope and remove one of them.
