Chapter 3: Functional Description
MegaCore Verification
A script defines sets of tests that cover a comprehensive set of parameters on RTL
VHDL simulation.
The testbenches can generate many patterns for the Avalon-ST interface testing and
all the possible scenarios are tested.
The first tests are carried out with noiseless data. Then tests using a subset of
signal-to-noise ratios, are carried out to evaluate the BER performance. The BER
performance matches the theoretical behavior of a Viterbi decoder ( Figure 3–17 on
page 3–20 ).

Signal-to-Noise Ratio
Another subset of parameters are tested with noiseless data using post-synthesis Vital
VHDL netlist.
The set of test patterns and parameters are comprehensive and should detect any
malfunction in any of the features or parameter sets of the hybrid and parallel
architectures.
