ILA Model
Defining ILA models
To start defining an ILA model, the first thing is to create an Ila
object at the top-most level.
auto m = ilang::Ila("model_name");
The object hierarchy is structured based on the ILA formal model:
ILA
+- Architectural states
| +- Inputs variables (leaf nodes of type Boolean or bit-vector)
| +- State variables (leaf nodes of type Boolean, bit-vector, or memory)
|
+- Instructions
| +- Decode function: expression (bit-vector)
| +- State update functions: expression (same type as the state)
|
+- Valid function: expression (Boolean)
|
+- Fetch function: expression (bit-vector)
|
+- Initial conditions: expression (Boolean)
|
+- Child ILAs
Note: expressions are the AST tree where input and state variables are the leaf nodes.
