Running C Simulation and C Synthesis - 2023.1 English - XD099

First, you will run C simulation to confirm the optimized design works as expected. Edit the tsp.h file to make sure the number of cities is small (N=5) for faster simulation run times and Run C Simulation.

After reviewing the results of simulation, increase the number of cities again (N=13) in the tsp.h file for C synthesis so that you can compare results with the original design. Run C Synthesis.

The following figure shows the C synthesis report in the Vitis HLS GUI (the Performance and Resource Estimates section):

You will notice that:

• The latency for the tsp function is now less than a second.

• The loop distance trip count is unchanged as expected since the input data is same.

• The tripcount for the main loop (loop_compute) is now a fourth of factorial 12 (12!/4) thanks to the parallel execution of the compute function.

• The new Loop 3 originates from the final std::min call that returns the smallest of the four results obtained.
