Figure 3-12: Created DIMM Device Group 
The device GUI for the children of “Dimm DDR2 1GBx2 #0” would look like this: 
Figure 3-13: Children of DIMM Device Group 
If we  looked at the options  and configuration of  the device  library “->  Machine #1 -> 
Dimm DDR2 1GBx2  #0 -> Dimm Bank  #0” (either from the  GUI or from  the console), 
we would see that it is already configured as DDR2 with 2 dimm slots (1GB each). 
This example demonstrates  a broad concept. An existing  device that has a more generic 
and abstract  definition (such  as a non-configured  “Dimm Ban k”) can be  wrapped in  a 
device group to  give it an  identity as a particular  hardware implementation (such  as an 
already configured “Dimm DDR2  1GBx2”). More generally, any device  can be wrapped 
by  a  device  group,  to  give  an  alternate  default  configuration  for  the  device‟s  state 
(archive data). 
15.1.5.2  Example: Quad-Core Node 
Next we will consider examples relevant to the  ability of a device group to have multiple 
child devices,  default archive data  for each  child device, and  connections between the 
child devices. These next examples are based on a quad-core processor node. 
Building a processor  node in SimNow  has traditionally been a  multi-step process. First 
the user  would add the  "AMD 8th  Generation Northbridge Device",  and then  add one 
"AweSim Processor"  device for  each processing  core in the  node. These  devices then 
need to be connected together along  the respective "CPU Bus" and "Interrupt / IOAPIC"
