-- be aware of the correct order!
-- EDA compiles from left to right

-- 1) gate entities 
-- 2) architectures for the gate entities
-- 3) Package (must be done after 1, because otherwise componante is not known)
-- 4) your entity
-- 5) your architecture (needs to know all above)
-- 6) Testbench Entity
-- 7) Testbench Architecture (in same file as testbench entity)


-- This example is related to the first VELS taks using packages (if there is no package, skip step 1-3)
