Three-dimensional NoC noise model and simulating method thereof

Abstract

The invention discloses a tridimensional NoC noise model, which consists of a system power supply encapsulation equivalent model, a power supply distribution network equivalent model, a signal line pi-mode equivalent model and a tridimensional crosstalk model. The invention further discloses a simulation method for the tridimensional NoC noise model based on the tridimensional NoC noise model. Thesimulation method comprises the following steps: (1) the parasitic parameters and the driving power parameters of the system power supply encapsulation equivalent model, the power supply distributionnetwork equivalent model, the signal line pi-mode equivalent model and the tridimensional crosstalk model are acquired; (2) an artificial circuit is established according to the tridimensional NoC noise model; (3) the constraint conditions of the exotic environment are set; (4) a simulation tool is operated for simulation; (5) the sampling result at an hour is acquired according to the simulation, thus acquiring the equivalent distribution of all noise. By adopting the tridimensional NoC noise model, not only a noise source subject to Gaussian distribution is simulated; but also a noise source not subject to Gaussian distribution is simulated. The tridimensional NoC noise model is mainly applied on network on chip.

technical field

[0001] The invention relates to a noise model and a simulation method thereof, in particular to a three-dimensional NoC noise simulation system and a simulation method thereof. Background technique

[0002] The research on the network on chip started in 1999, the original intention of the research was to explore the system-level design method of the communication part of the system on chip. Soon, research involved everything from physical design to architecture, operating systems, and applications. At present, the concept of a network on a chip is very broad, including hardware communication structure, middleware, operating system communication services, and design methods and tools. From the perspective of system structure, the research focus of the network on chip is the topology structure of the network on chip, the protocol of the network on chip, the quality of service of the network on chip and the low power consumption of the network on chip.
