Card Unit Test Description
Appendix A - Falcon Diagnostic Tool
Video+ CM PCI Scans the PCI to ensure that its
components are working
properly.
Memory Checks buses’ data and
addresses.
Checks memory integrity and
capacity.
TDM Creates a loop between the DSP
through the backplane and the
BCOD then back to the DSP via
the time slot switch to check data
transfer through the loop.
BCOD Checks the H-sync and F-sync
clocks and BCOD memory.
Proc Memory Checks buses’ data and
addresses.
Checks free memory.
Clock Checks the frequency rate of the
processor.
MCU Level Tests
When the Falcon diagnostic tool is run at the MCU level, all available tests are run on all
the recognized cards installed on that MCU and their units. Several MCUs can be tested
simultaneously, and their tests run serially.
Card Level Tests
When the Falcon diagnostic tool runs tests on an installed recognized card, it performs all
the available tests on all the card’s component units. You can test all cards of a certain type,
for example, all the Video+ cards. All tests run on the Falcon diagnostics tool are run
serially rather than simultaneously.
Unit Level Tests
At the unit level, tests can be selected individually. A specific test, for example, the TDM
test, can be run on all cards installed on the MCU as long as each test is initiated
individually. The tests run serially.
