Abstract

The invention discloses a parameter combination collection method, device and system of a transmission line model and a computer readable storage medium. The method comprises the steps: obtaining eachgroup of transmission line parameter information, and each group of transmission line parameter information comprises a parameter name and each parameter value corresponding to the parameter name; writing each parameter value in each group of transmission line parameter information into each data position corresponding to the parameter name according to each preset combination requirement; combining the parameter values at the same data position under each parameter name to obtain a parameter combination corresponding to each preset combination requirement; in the using process, the parametercombinations corresponding to the preset combination requirements can be obtained at a time, secondary screening is not needed, the workload is reduced, and the obtaining efficiency of the parametercombinations of the transmission line model is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of high-speed serial channel simulation, and in particular to a method, device, system and computer-readable storage medium for obtaining a combination of parameters of a transmission line model. Background technique [0002] In high-speed serial channel (HSS) simulation, in order to accurately simulate the performance of high-speed channel, PCB transmission line modeling is very important. Manufacturing tolerances can cause significant variations in PCB transmission line impedance and loss, and these tolerances must be accounted for when modeling to obtain worst-case PCB transmission line performance. [0003] There are many parameters that are affected by manufacturing tolerances and thus affect transmission line impedance and loss, such as line width, line spacing, dielectric thickness, copper thickness, etc. Therefore, it is necessary to perform parameter traversal on the standard v...

Problems solved by technology

The disadvantage of this scheme is that only one set of simulation data can be obtained at a time, and multiple simulations are required to obtain the required corners data

The advantage of this method is that all parameter combination data can be obtained by running the simulation only once. The disadvantage is that all parameter combinations are simulated, and the simulation data is large, and the required corners data cannot be found in all the data at a glance during post-processing. Filter and get the required corners
