Structure-irrelevant micro-processor verification and evaluation method

Abstract

This invention relates to a checking and evaluating method about structure independency micro processing unit (abbreviation THUMPSim), which belongs to the micro processing unit chip checking and evaluating technique field. It is a micro processing unit simulative and checking method which is independent of system structure describing the simulative micro processing unit by facing part structure independency system structure defined method and processing simulated drive by event driven signal renewal arithmetic.

Description

technical field [0001] Structure-independent method for verification and evaluation of microprocessors (THUMPSim) belongs to the technical field of verification and evaluation of microprocessors Background technique [0002] In the design and implementation technology of microprocessor architecture, a software simulator with accurate clock-level signals has very important research value and practical significance. play a vital role. [0003] In the microprocessor design process, after the architectural design work is completed, the first thing to do is to verify the logical correctness of the design, that is to say, to check whether the architecture can operate normally in various situations without appearing In order to solve the problem, it is necessary to further evaluate whether the design has reached various technical performance indicators. In the past, these verification and evaluation tasks relied on microprocessor designers to write corresponding RTL-level (regist...

Problems solved by technology

[0010] 2. Although some simulators reflect all the details of the architecture, because there are many details to be simulated, and the design of the simulation algorithm itself is not optimized enough, the simulation speed is slow, making the verification and evaluation work unable to be carried out quickly. Lost the meaning of software simulator

[0011] 3. Some simulators take into account the requirements of architectural details and simulation speed, but make the simulator itself complex in structure, low in modularization, heavy in programming workload and inconvenient in debugging, which is not suitable for multi-person collaborative development

Moreover, in order to adapt to changes in hardware design, simulators often need to be modified many times, and the complex software structure will also cause great difficulties for simulator programmers.

[0012] 4. There are still some simulators that have less consideration for portability. Most of these simulators adopt the implementation scheme of formulating the simulator software structure according to the architecture. The code of the simulator itself is closely combined with the architecture definition code. To simulate another architecture, the simulator has to be compiled from scratch, and code reuse cannot be achieved
