vhdl examples (part 7) Laboratory reports penultimate

Good day ... I hope you super fence ... well this is our penultimate delivery of basic examples in VHDL
would fail only perform sequential machines mealy and moore ... the last delivery of these examples show .. they are relatively simple, well-placed only with the clock event (rising edge) ...

Example 22:
Designing in VHDL, a 4-bit up counter with 1Hz clock.
Solution:

Well hope to be of show digital clock and timer, but will not be possible to finish the semester and I have no time ... a very helpful suggestion, if you can not design in vhdl leguaje the easiest way to present the work in laboratories simulation is to capture or schematic using quartus2 WebPack xilinx ise because simulators are schematic capture all basic components for any digital work and is only grasping the component and connecting cables or proteus as
