Vme Interface Tests - DEC Digital Alpha VME 4/224 User Manual

VME Interface Tests

VME Interface Tests
These tests verify the VME interface logic on the Digital Alpha VME 4
module, including the VME interface processor (VIP), the Cypress VIC064,
the scatter/gather RAMs, and some of the interrupt paths from the VME corner
to the Alpha processor. No VMEbus transactions are performed by these tests
and therefore require no additional VMEbus modules.
VIP PCI Configuration Register Test
This test reads the first 8 longwords of VIP PCI configuration space. Only
the device and vendor ID, and base address 0, 1, 2, and 3 are compared to an
expected value. The remaining longwords are always read and displayed only if
the -dd option is present.
Console Command: vip_diag -t 1
Command Option:
-dd: print detailed test information.
VIP Register Write/Read Test
This test ensures that the bits of a VIP register can be written and read correctly;
verifying the data path and internal access.
Console Command: vip_diag -t 2
Command Option:
-dd: print detailed test information.
VIC Register Write/Read Test
This test ensures that the bits of a VIC register can be written and read correctly;
verifying the data path and internal access.
Console Command: vip_diag -t 3
Command Option:
-dd: print detailed test information.
