The collaborative simulation accelerator can interact with a simulation software of the simulation computer for data interaction and collaborative operation, a simulation operation task is completed by working together, the simulation speed and efficiency are high, the simulation time is very short, the accelerator is simple in structure, small in volume, easy to produce and process, and low in cost.

Description

【Technical field】 [0001] The invention belongs to the technical field of circuit function simulation, and in particular relates to an FPGA-based collaborative simulation accelerator, a simulation system and a method. 【Background technique】 [0002] At present, in the design of chips / programmable logic devices, when performing functional simulation on circuits, the existing traditional method is to use simulation software (such as Modelsim, Questasim, VCS, NC_Sim, Active-HDL, etc.) on a computer (PC) Or perform software simulation on the server (server). This traditional simulation method is a pure software simulation method. Since the calculation of the entire simulation process is completed by the central processing unit of the computer or server, the simulation speed is extremely slow and time-consuming, especially in the later stage of design, and regression is required. During the test, the circuit scale is huge and there are many simulation scenarios. It takes hours, d...

Problems solved by technology

This traditional simulation method is a pure software simulation method. Since the calculation of the entire simulation process is completed by the central processing unit of the computer or server, the simulation speed is extremely slow and time-consuming, especially in the later stage of design, and regression is required. During the test, the scale of the circuit is huge and there are many simulation scenarios. It takes hours, days or even weeks to use the traditional software simulation method, which leads to a greatly extended product development cycle and a relatively sharp increase in research and development costs, which ultimately reduces the Product market competitiveness
