Development of a UVM-Based Verification Platform for the OSPI Interface

With the increasing complexity of chip functionality, the task of design verification faces greater challenges, Traditional waveform-based simulation methods are not only time-consuming and labor-intensive but also struggle to cope with growing system complexity. To enhance verification efficiency and ensure reusability, the industry urgently needs a standardized verification framework. Currently, although Register Transfer Level (RTL) designs are typically implemented in Verilog, the lack of unified verification standards makes it difficult to effectively reuse and share verification efforts. Octal Serial Peripheral Interface (OSPI) interfaces are increasingly prevalent in consumer electronics, especially in mobile terminals, due to their high data throughput and low power consumption advantages that effectively meet storage and application needs. This study constructs a standardized verification platform based on UVM, specifically targeting the OSPI interfaces within System on Chip (SoC) architectures. A series of adaptable verification components are developed to meet the specific requirements of the Device Under Test (DUT). The platform can automatically generate constrained random test stimuli and utilizes functional coverage as the primary metric to quantitatively evaluate verification processes and results, thereby efficiently ensuring the functional completeness and reliability of OSPI interface designs.
