JSON simulation configuration file
In addition to the SST Python module interface, SST also provides a standard JSON interface for which to build configuration files. The JSON SST configuration files support all the standard features of a Python configuration file as a set of name-value pairs or arrays of name-value pairs. The JSON configuration format contains the following major sections:
- Program Options: Configures general simulation options
- Shared Parameter Sets: Creates shared parameter sets for use with components/subcomponents
- Global Statistics: Enables global statistics and statistics options
- Components (and subcomponents): Creates and parameterizes components and subcomponents
- Statistics Groups: Creates and parameterizes groups of statistics
- Links: Creates and connects links between component/subcomponent ports
Value Types
The following types will be utilized to describe the value of each potential configuration option.
- Integer: describes a standard integer value
- UnitAlgebra: describes a value in UnitAlgebra form such as 1GHz or 1ps. See UnitAlgebra
- Bool: describes a boolean value as either True or False
- String: describes a value as a string
- Type: describes the values for parameter names that can be any of the aforementioned types
Ordering Constraints
The JSON reader streams objects and arrays iteratively in order of their discovery. As a result, there are number of ordering constraints that must be adhered to in order to successfully parse and create the SST configuration graph from JSON. We denote the ordering constraints as follows:
statistics_groupmust appear aftercomponents. Thestatistics_groupreference component objects that must be present in the SST config graph- For each
componentorsubcomponentobject, thenameandtypevalues must appear before any other values. This ensures that the parser can create the component or subcomponet objects before adding parameters or statistics values to the resident config graph object.
