A Distributed Simulation Method Based on tlm System Model

Abstract

The invention discloses a distributed simulation method based on a TLM system model. Starting from the algorithm simulation of the TLM system modeling module (1), the entire algorithm simulation process is divided into several time periods as required, and the time-sharing state generation module (2 ) to generate a time-sharing state file, record important system state values ​​at the end of each time period, and distribute the loading module (3) to read the time-sharing state file and convert different state values ​​into different RTL simulation initial values, and the simulation result analysis module (4) Multiple time period simulations are performed in parallel according to different initial values, and the simulation results are distributed and comparatively analyzed by the simulation result analysis module (5) to complete the entire process of distributed simulation. This simulation method solves the problems of slow speed and many iterations of the traditional simulation method.

Description

technical field [0001] The invention relates to a distributed simulation method, in particular to a distributed simulation method based on a TLM system model. Background technique [0002] In the current simulation method, verification efficiency has become an important bottleneck restricting the progress of SoC development. On the one hand, since most RTL simulation tools cannot perform multi-core parallel simulation, the verification time of large-scale digital SoC is too long, and the simulation verification of a chip-level test stimulus needs to wait for a week or more to get the result. On the other hand, since the simulation is continuous in time, a large number of meaningless simulations are required before the simulation results at the desired time point are obtained. This phenomenon is very common in repeated verification iterations and wastes a lot of simulation time. In order to solve the above problems, the industry mainly adopts the following methods: [0003]...
