No assumptions or check on the inputs have to be performed to generate the VHDL: (vcom-1136: std_logic_vector undefined) syntax,vhdl. The use of IEEE.std_logic_1164.all is also required before the entity, like: library IEEE; use IEEE.std_logic_1164.all; entity lab2 is The first IEEE.std_logic_1164.all only applies to the package, and package body of the same package, but not to any other design objects like an entity or package, even if these happens to The state machines are modeled using two basic types of sequential networks- Mealy and Moore. In a Mealy machine, the output depends on both the present (current) state and the present (current) inputs. In Moore machine, the output depends only on the present state. Mealy Outputs 1 Mealy Outputs Mealy state machines in VHDL look nearly the same as Moore machines.

Port ( clk : in STD_LOGIC; 2017-09-02 Regarding the VHDL acronym, the V is short for yet another acronym: VHSIC or Very High-Speed Integrated Circuit. The HDL stands for Hardware Description Language. Clearly, the state of technical aﬀairs these days has done away with the need for nested acronyms. VHDL is a true computer language with the accompanying set of syntax and usage rules. 2011-09-29 Mealy or Moore depends on how you code your outputs.
