Only the clock and optional asynchronous reset signals belong in a sequential sensitivity list.
Maintain consistent indentation and block structure to make code layout intuitive. B. Modularity and Abstraction Avoid writing one giant entity. effective coding with vhdl principles and best practice pdf
Only standard IEEE ( 1164 , numeric_std ) are utilized. No legacy math packages. All bus dimensions and buffer depths are parameterized. Processes Only the clock and optional asynchronous reset signals
Do this:
A latch is inferred when a combinatorial signal is not assigned a value under all possible execution paths. Latches complicate timing analysis and degrade design reliability. effective coding with vhdl principles and best practice pdf
