Page 13: Overview
The AMD SimNow™ simulator is an AMD64 technology-compatible x86 platform simulator for AMD's family of processors. It is designed to provide an accurate model of a computer system from the program, OS, and programmer's point of view. It allows fast simulation of an entire computer system, plus standard debugging features such as break- pointing, memory-viewing, and single-stepping.
Page 14 The graphics device supplied with the simulator is a 2D and 3D graphics card with linear frame buffer and DirectX 6 support. AMD currently plans to provide a graphics model with the simulator which will also have modern 3D hardware acceleration, including Microsoft®...

To the user, the composite device will look and feel no different than a normal device library and, for the most part, the two should be indistinguishable.

Page 34: Example: Quad-Core 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"...

Page 36: Example: Superio Device
User Manual This is not the only way we could create a (theoretical) “AMD 4-core CPU xxxx”. A cleaner idea would be to reuse the non-configured abstract and generic “4 core Node”. This device group would (externally) be functionally the same as our previous “AMD 4- core CPU xxxx”...

The Device Properties Window is used to set various processor identification and behavior options. Figure 7-1 shows the Processor Type tab for the AweSim processor device. Here you can specify which member of the AMD microprocessor family should be simulated. The default is a standard AMD microprocessor. See Section A.2.3, Product Files (*.ID), on page 179.

Page 69 While the processor device is a faithful simulation of the software-visible portion of an AMD microprocessor, it is not a model of the specific AMD microprocessor hardware. Because of this, the processor device is not equivalent in certain areas. Any issues related to timing, such as the time to execute a given instruction, will be different.

Page 71: Dimm Device
PDL per byte of width (eight total PDLs). DIMMs that use 4-bit devices use one PDL per nibble (16 total PDLs). The memory controller in the AMD Opteron™ processor includes two DDR channels that are ganged into a single effective 128-bit interface. Each access to memory hits a pair of 64-bit DIMMs, where one DIMM supplies the lower 64 bits while the other DIMM supplies the upper 64 bits.
Page 72 DIMM. The number of DIMMs supported in the DIMM Device model is dependent on the type of CPU used in the system. If the CPU type is an AMD Opteron processor, then the DIMM Device will assume a 128-bit memory interface and therefore allow configuration of up to eight individual DIMMs.
Page 73 AMD Confidential User Manual November 21 , 2008 Once the simulation is started, the DIMM Device allocates memory arrays to hold the DRAM data. One array is allocated for each bank or virtual bank. In the case of 64-bit memory interfaces, memory arrays are allocated to match the size of the physical banks on each DIMM.
Page 74 AMD Confidential User Manual November 21 , 2008 Figure 7-5: DIMM-Bank Options Properties Dialog Figure 7-5 shows the dialog for configuring DIMM-bank options. The PDL Error Simulation Control section specifies the type of error that the DIMM device will generate, when a memory read is attempted and when a Northbridge PDL is set outside the valid response range.
Page 75 AMD Confidential User Manual November 21 , 2008 Figure 7-6: DIMM Module Properties Dialog The two DIMM module configuration dialogs, shown in Figure 7-6, (DIMM0 – DIMM1) provide module-specific setup options for each simulated DIMM. The two DIMM module configuration dialogs share the same format.
Page 76 AMD Confidential User Manual November 21 , 2008 The upper part of the dialog lists some summary information. This information, which is derived from the SPD data, gives a quick indication of the type of device being simulated. The center section of the dialog lists all 256 bytes of data held in the simulated SPD ROM.

Interface The Northbridge device has several connection points. It has multiple HyperTransport bus ports that connects to the other AMD 8th Generation Integrated Northbridge devices, or to HyperTransport link-capable devices (e.g., AMD-8131 PCI-X device). These ports are mutually exclusive, and should be connected to only one other device. The Northbridge also has a memory bus to the DIMM devices.

Page 175 AMD Confidential User Manual November 21 , 2008 Figure 13-1: DiskTool Shell Window DiskTool will only copy drives - not partitions, although it does have the ability to stop copying at the end of a given partition. So, for example, you can copy the contents of a drive starting at the beginning of the drive and ending at the end of the 2nd partition, but you can not copy only the 2nd partition.
Page 176 AMD Confidential User Manual November 21 , 2008 Figure 13-2: DiskTool GUI Window You may select any physical drive in your system, including floppy drives. Selecting a drive updates the Drive Information list box as shown in Figure 13-3. Note: DiskTool does not support Serial ATA (SATA) drives!
Page 177 AMD Confidential User Manual November 21 , 2008 When a drive is selected, you have the option to get an image from the drive, put an image onto the drive, or erase the contents of the drive. If you erase the contents of the drive, a dialog will ask for confirmation that you actually wish to permanently destroy the contents of that hard disk.
