Quick Start

Run simulation in Modelsim. The testbench reads a bitmap from imgs/ (defined in src/global.vh and writes the processed image to a bitmap in out/. The output should be readable by any image viewer.

vsim -c -do sim/run_sim.do

To pull up gui:

vsim -do sim/gui.do

Vivado Flow

Run through synthesis, implementation in Vivado. Writes post-synth and post-impl netlists. A vivado project is created in the directory viv/.

vivado -mode batch -source vivado.tcl

To pull up gui, run above command and

vivado $(find . -type f -name '*.xpr')

Debugging

Output a bitmap as hex, grouped by pixel xxd -cols 12 -g 3 -s 0x0000008a out.bmp out.xxd
