| Popis: | In this paper we present the development of Acceleratable UVCs from standard UVCs in System Verilog and their usage in UVM based Verification Environment of Image Signal Processing designs to increase run time performance. This paper covers development of Acceleratable UVCs from standard UVCs for internal control and data buses of ST imaging group by partitioning of transaction-level components and cycle-accurate signal-level components between the software simulator and hardware accelerator respectively. Standard Co-Emulation API: Modeling Interface (SCE-MI) compliant, transaction-level communications link between test benches running on a host system and Emulation machine is established. Accelerated Verification IPs are used at UVM based Verification Environment of Image Signal Processing designs both with simulator and emulator as UVM acceleration is an extension of the standard simulation-only UVM and is fully backward compatible with it. Acceleratable UVCs significantly reduces development schedule risks while leveraging transaction models used during simulation. In this paper, we discuss our experiences on UVM based methodology adoption on TestBench-Xpress (TBX) based technology step by step. We are also doing comparison between the run time performance results from earlier simulator-only environment and the new, hardware-accelerated environment. Although this paper focuses on Acceleratable UVC’s development and their usage for image signal processing designs. Same concept can be extended for non-image signal processing designs. |
