There are currently two different file formats to describe the address mapping. This software automatically chooses the correct interpreter using the file extension as selection criterion. So please make sure that all files have the correct extension.
There are currently two different file formats to describe the address mapping. This software automatically chooses the correct interpreter using the name of the xml root node as selection criterion.
- **XML file format**
- **Standard XML file format**
XML files describe the address mapping to be used in the simulation.

- **JSON file format**
- **ConGen XML file format**
This file format is generated by ConGen. It does not have an unambiguous assignment of the address lines.
This file format is generated by ConGen.
The format delivers more information than needed for an address mapping.
Unused data:
- Block "Config": Gives you information about the ConGen configuration
- Key "Name": Name of the trace file which was used by ConGen
- All items of the array "Solutions" but the first one: Alternative solution with same result.
- Key "costs": Number of row misses which this configuration produces while playing the trace.
- "NAME": Name of the trace file which was used by ConGen
- "COSTS": Number of row misses which this configuration produces while playing the trace.
Used data:
- First item of array "Solution":
- "XOR": Array of row and bank bits which are connected with an xor. Order of the bit: bank1, bank2, ..., row1, row2, ...
- "bank_bits": Number of the addres bits which are connected to a bank bit
- "row_bits": Number of the addres bits which are connected to a row bit
- "CONFIG": Gives you information about the ConGen configuration
- "SOLUTION":
- Attribute "ID": Unique identifier for this solution. It is used to specify a certain solution.
- "XOR": Defines an xor connection of a bank and row bit
- "BANK_BIT": Number of an address bit which is connected to a bank bit
- "ROW_BIT": Number of an address bit which is connected to a row bit
