Background technology
At present, the method not having a standard individually for the performance test methods of EDA design platform system, general class
Also it is concentrated mainly on reference test method like the method for testing for system application platform performance, i.e. takes formulation to meet necessarily
The method of theoretical validation rule, instrument and system, thus the related performance indicators of a certain class testing object is quantitatively surveyed
Examination and can contrast test.Wherein, benchmark test can be divided into three kinds: microcosmic test, macro-test and tracking reappear method.
Microcosmic test mainly for treating that examining system some or multiple concrete operating characteristics are tested, its test load
Generally it is made up of different types of operation, and verifies file system feature in a certain respect or in terms of some with this.It is excellent
Point is can be from the performance in terms of the angle of microcosmic helps customer analysis and understands some feature of file system, and test result is succinct
Understand；But weak point is: easily cause test coverage low, and the microcosmic on independent hardware is tested reflected performance and is difficult to
Weigh the real work performance of total system comprehensively.
Macro-test is to treat that the real work load of examining system is treated the combination property of examining system and commented by simulation
Estimate.It uses closing to reality load request as far as possible to carry out treating the Behavior modeling that examining system is applied.Its advantage is can be from similar reality
The angle of load simulates the current demand of typicality；The most this method equally exist such as type single, load deviation, join
Put the problems such as dumb.
Following the tracks of reproduction rule is by gathering the System Operation Log record to be measured under actual loading, and according to the lattice set
Formula record is being followed the tracks of in file, then when test according to the track record followed the tracks of in file collected again to system to be measured
System proposes read-write requests, and the true application behavior thus treating examining system carries out Performance Evaluation.

Emulation content, continuously perform set point number post-simulation operation；
(IV) while (III) step is carried out, all circuit simulation threads are monitored by main thread, until all of emulation
Thread end of run.
