Describing Multi-Processor Systems-on-Chip (MPSoC) at the abstract Electronic System Level (ESL) is one task, validating them efficiently is another. Here, fast and accurate system-level simulation is critical. Recently, Parallel Discrete Event Simulation (PDES) has gained significant attraction again as it promises to utilize the existing parallelism in today's multicore CPU hosts. This paper discusses...
Editor's note: To address the limitations of discrete-event simulation engines, this article presents an extension of the SoC simulation kernel to support parallel simulation on multicore hosts. The proposed optimized simulator enables fast validation of large multicore SoC designs by issuing multiple simulation threads simultaneously while ensuring safe synchronization.
Design at the Electronic System-Level (ESL) tackles the increasing complexity of embedded systems by raising the level of abstraction in system specification and modeling. Aiming at an automated top-down synthesis flow, effective ESL design frameworks are needed in transforming and refining the highlevel design models until a satisfactory multi-processor system-on-chip (MPSoC) implementation is reached...
Dynamic meshing of Spiral bevel gears is a complicated geometric, material, and contact non-linear problem. The finite element method (FEM) is a common and effective approach and direct constraint method is highly advantageous to solve contact non-linear problems. In this paper, a three-dimensional nonlinear contact analysis model for a pair of spiral bevel gears was established. Based on this model,...
