Problems solved by technology

[0005] In order to verify the correctness of the logic function of the entire device chip or circuit chip, a lot of verification work must be done, but the larger the circuit size, the netlist file may even reach 700MB, using the simulation based on ncverilog of candence company and vcs of synosys company tools, run functional simulation of large-capacity circuits, the time required for a verification may be as long as a week, and it takes the same time to re-verify after an error is found
At the same time, it takes up a lot of server resources

Abstract

The invention provides a netlist exporting method for device function simulation, a server and a storage medium. The netlist exporting method comprises the following steps: determining netlist contents and formats required to be exported in function simulation of a target device model according to a spice model; defining a simulation function of the netlist and a CDF file of the target device model according to confirmation information in the spice model; and traversing the CDF file by using the simulation function of the netlist, reading the information defined by the netlist in simulation, generating the netlist file according to the read information classification, and exporting the netlist file. Therefore, the netlist file of the device model can be quickly and accurately defined and modified, simulation is facilitated, the project progress is accelerated, and the working efficiency is improved.

Description

technical field [0001] The present disclosure relates to the technical field of integrated circuits, and in particular, to a netlist derivation method, a server and a storage medium used in device function simulation. Background technique [0002] An integrated circuit (Integrated Circuit, IC) board diagram is an intermediate link between a circuit system and an integrated circuit process, and is an essential and important link. Layout design is a link of physical realization, and also an important transition from symbolic circuit diagrams to actual physical layers. Through integrated circuit layout design, a three-dimensional circuit system can be transformed into a two-dimensional plane figure, and then processed by technology. reduced to a three-dimensional structure based on silicon materials. [0003] With the development of microelectronics manufacturing technology to the deep sub-micron direction, the integration of digital integrated circuits is also getting higher ...
