SmartDV’s I2C AIP is a fully featured SVA-based formal verification IP purpose-built for SoC designs requiring exhaustive, property-driven verification of I2C protocol compliance across sensor interfaces, EEPROM controllers, power management peripherals, and mixed I2C/SMBus bus fabric designs. Fully compliant with I2C v7.0, it delivers a comprehensive set of SystemVerilog Assertions targeting the full breadth of I2C protocol rules including Start and Stop condition timing, ACK/NACK sequencing, clock stretching correctness, multi-master arbitration, 7-bit and 10-bit addressing, and repeated start sequence validity.
Designed to complement simulation-based verification with the exhaustive state space exploration that only formal methods can provide, the AIP targets the class of subtle I2C protocol bugs including illegal Start/Stop conditions, clock stretching deadlocks, arbitration race conditions, and addressing errors that are statistically unlikely to surface in directed or constrained-random simulation but can cause peripheral communication failures in silicon. Its parameterized constraint and assumption architecture allows formal tools to focus verification effort on the most critical protocol properties while bounding the state space to tractable problem sizes.
Compatible with industry-standard formal verification tools and fully independent of any specific EDA vendor platform, the AIP integrates cleanly into existing formal flows with minimal setup overhead. Its modular property organization, configurable speed mode parameters, and clear assertion naming conventions enable verification teams to rapidly deploy, customize, and extend the property set to match the specific I2C configuration and design context of their SoC.
