chronSIMD-Vois Border

chronSIM is a tool for the design, simulation, and verification of embedded systems with an explicit focus on real-time. Processors and communication buses, scheduling and stimuli are described in timing models using either the intuitive GUI or with C/C++ source code.

chronSIM enables engineers and system architects to assess the extent to which real-time requirements are met – across all phases of the development process.
