Pragma hls loop_tripcount
WebLoop Unrolling (unroll Pragma) 6.4. Loop Unrolling (unroll Pragma) The Intel® HLS Compiler supports the unroll pragma for unrolling multiple copies of a loop. Example code: #pragma unroll for (int i = 0; i < M; ++i) { // Some useful work } In this example, specifies the unroll factor, that is, the number of copies of the loop that the ... WebWhen we open the analysis view, we will be presented with information under the module hierarchy, indicating which module if any, is presenting a timing violation or initiation interval violation. If we only want to focus on the violations, we can click on the timing or II violation button at the top of the module hierarchy.
