Section combined stress section is consistent；
Step 7, determine software encourage
Software is encouraged, and is to determine particular content, quantity and applying that software is input into sequentially according to comprehensive software and hardware section, software
Excitation is determined using following algorithm：
7.1：According to combined stress section hpi, and mapping function f (so) obtains corresponding software Operation Profile SOp, take with
The mode selection operation of machine sampling；
7.2：According to input data InputValue, the distribution situation sot on the time determines the specific input data of operation
InputValue；
7.3：Repeat to extract up to software encourages the duration consistent with each section of combined stress section duration, then stop.
