2000
Total samples to transfer during simulation.
Mode (
mode
)
Continuous/burst
The testbench environment may automati‐
cally choose one of the modes depending on
the random seed with which it is provided.
Refer to the simulation scripts listed in
for details.
Skew insertion enable
(
skew_insertion_enable
)
Yes
Skew testing is enabled. The testbench
environment randomly inserts skew in the
lanes within the range 0 - 107 UI.
ECC protection enabled
(
ecc_enable
)
0
When set, the core is simulated with the
ECC-enabled variant. Use the ECC-enabled
variant in the test environment.
When ECC mode is disabled, the two most
significant bits of the error buses in the
source or sink direction are don't care.
