Pipelining Lab 1: Baseline Matrix Multiplication Project

Read source files

  • matrixmul.cpp contains the top function of matrix multiplication
  • matrixmul_test.cpp is the test bench (with software verification)
  • run_hls.tcl is the Tcl file running just C simulation and synthesis
    • Note the device part number and clock frequency

Run C Simulation + Synthesis

vivado_hls -f build run_hls.tcl

Check Resources and Timing Report

cat matrixmul_prj/solution1/syn/report/matrixmul_csynth.rpt
  • For the timing, you should see
