ILAng is a platform for modeling and verification of systems-on-chip (SoCs) using Instruction-Level Abstractions (ILA). The ILA formal model targeting the hardware-software interface enables a clean separation of concerns between software and hardware through a unified model for heterogeneous processors and accelerators. Top-down it provides a specification for functional verification of hardware, and bottom-up it provides an abstraction for software/hardware co-verification. ILAng provides a programming interface for (i) constructing ILA models (ii) synthesizing ILA models from templates using program synthesis techniques (iii) verifying properties on ILA models (iv) behavioral equivalence checking between different ILA models, and between an ILA specification and an implementation. It also provides for translating models and properties into various languages (e.g., Verilog and SMT LIB2) for different verification settings and use of third-party verification tools.
