6 Work procedure Well defined responsibilities for each subgroup. The subsystems were merged together at the end. Each group adopted their own form of programming approach. Revision control using GIT.

7 Troubles and experiences GIT issues when using HDL-designer. Troubles with integrating the VGA-controller with the rest of the system.

8 Advantages of M.E.S.S Only about 10% of FPGA used User friendly Good margins Advanced filters with up to 500 coefficients
