Problems solved by technology

However, due to the complexity of the system architecture, the high-speed bus often runs through multiple PCB boards. When simulating and extracting models, it is necessary to establish via models and transmission line models for each board with different stacks, which will consume a lot of time and affect project progress

Abstract

The invention provides a simplified CCT (channel check tool) pre-simulation method. CCT provides a convenient pre-simulation method for signal loss influence of actual routing environments in PCB (printed circuit board) design, a powerful evaluation basis is provided for project early stage risk evaluation and design planning. The automatic simulation provides an effective and independent research process for developers, complete dependence on Intel design guidance is avoided, and creative products with self features can be developed. The pre-simulation result of a new project is compared with the simulation result of a developed project, the new project scheme is large in topology possibility if the pre-simulation result is better than the simulation value of the developed project, otherwise, risks and project scheme feasibility need to be evaluated, and the project schemes needs to be changed appropriately for simulation and comparison again.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a simplified pre-CCT simulation method. Background technique [0002] With the increasing signal rate, the actual wiring environment in PCB design has an increasing influence on the signal loss, resulting in an increasing risk of system signal stability. Therefore, to design a reliable, low-risk stable system, it is very important to simulate the actual routing environment of the signal and simulate the effects of signal attenuation and loss in the early stage of design. The channel check tool CCT (Channel Check Tool) hereinafter referred to as CCT provides a simple, fast and effective simulation method for pre-signal simulation. The simulation process is as follows: figure 1 As shown, compare the pre-simulation results of the new project with the simulation results of the existing projects. If the comparison result is better than the simulation value of the project that has p...
