Bus SP Tag heading can be DDR or PLRAM
and gives associated information below.
Segment Index field is used in
association with the
SP Tag to generate the associated memory
resource index as shown below.
Bus SP Tag[Segment Index]
For example, if
Segment Index is 0, then the
associated DDR resource index would be DDR.
This memory index is used when specifying memory resources in the
v++ command as shown below:
v++ … --connectivity.sp vadd.m_axi_gmem:DDR
There can be more than one
associated with an SLR. For instance, in the output above, SLR1 has both
Segment Index 1 and 2.
Consumption field indicates how a memory
resource is used when building the design:
- If the
--connectivity.spdirective is not specified, it uses this memory resource by default during
v++build. For example in the report below, DDR with
Segment Index1 is used by default.
- When the maximum number of memory interfaces have been used under
Consumption: defaulthave been fully applied, then the interfaces under
automaticis used. The maximum number of interfaces per memory resource are given in the Max Masters field.
- For PLRAM, consumption is set to
explicitwhich indicates this memory resource is only used when explicitly indicated through the
