Distributed simulation method based on TLM system model

Abstract

The invention discloses a distributed simulation method based on a TLM system model. According to the method, algorithm simulation is started through a TLM system modeling module (1), the whole algorithm simulation process is divided into a plurality of time periods according to a demand, a time-sharing state file is generated through a time-sharing state generation module (2), important system state values at the ends of all the time periods are recorded, a distributed loading module (3) reads the time-sharing state file, different state values are converted into different RTL simulation initial values, a simulation result analysis model (4) performs simulation in multiple time periods concurrently according to different initial values, distributed comparative analysis is performed on simulation results through a simulation result analysis module (5), and the whole process of distributed simulation is completed. Through the simulation method, the problems that traditional simulation methods are low in speed and have a large number of iterations are solved.

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]...
