BIST (Built-In Self Test)
The Stratix GX transceiver has built-in self test modes to aid in debug and
testing. The BIST modes are set in the Stratix GX MegaWizard Plug-In
Manager in the Quartus II software. Only one BIST mode can be set for
any single instance of the transceiver block. The BIST mode applies to all
channels used in a transceiver.
The following is a list of the available BIST modes:
■ PRBS generator and verifier
■ Incremental mode generator and verifier
■ High-frequency generator
■ Low-frequency generator
■ Mixed-frequency generator
Figures 2–24 and 2–25 are diagrams of the BIST PRBS data path and the
BIST incremental data path, respectively.
