About the Test Vectors
The example design has a host connected to an instance of the HyperTransport
MegaCore function configured as an end-chain link. When simulating the receive link
interface, the following events occur:
1. The host configures the end chain link’s BAR0 with 0xfa000000. It then writes
0x01 as the UnitID and 0x0007 in the command register of the device header
space.
2. The host writes double-word data with data ranging from 1 to 16 DWORDs to the
posted channel followed by a byte write with data ranging from 1 to 8 DWORDs.
3. The host writes double-word data with data ranging from 1 to 16 DWORDs to the
non-posted channel followed by a byte write with data ranging from 1 to 8
DWORDs.
4. The host performs a read request with data ranging from 1 to 16 DWORDs to the
non-posted channel followed by a byte read request with data ranging from 1 to 8
DWORDs.
Analyzing the transmit local-side interface, the following sequence of events occurs:
1. The local side writes double word data with data ranging from 1 to 16 DWORDs to
the posted channel followed by a byte write with data ranging from 1 to 8
DWORDs.
2. The local side writes double word data with data ranging from 1 to 16 DWORDs to
the non-posted channel followed by a byte write with data ranging from 1 to 8
DWORDs.
3. The local side performs a read request with data ranging from 1 to 16 DWORDs to
the non-posted channel followed by a byte read request with data ranging from 1
to 8 DWORDs.
