Because the RAM in the EAB is self-timed, this parameter can be ignored when the WE signal is registered.
Microparameters are timing delays contributed by individual architectural elements. These parameters cannot be
measured explicitly.

EAB macroparameters are internal parameters that can simplify predicting the behavior of an EAB at its boundary;
these parameters are calculated by summing selected microparameters.
These parameters are worst-case values for typical applications. Post-compilation timing simulation and timing
analysis are required to determine actual worst-case performance.
External reference timing parameters are factory-tested, worst-case values specified by Altera. A representative
subset of signal paths is tested to approximate typical device applications.
