摘要
HLA时间管理中lookahead值是在仿真执行过程中由用户自己设置的.在实际仿真系统中,寻找合适的lookahead值是比较困难的,为了进一步提高仿真运行的效率和改善仿真运行的效果,本文对lookahead的调整与设置问题进行了研究.引入lookahead的初衷是避免死锁,但looka-head为零仍会造成死锁.本文研究了lookahead为零时死锁的规律,了解这些规律后,就能有效地避免死锁,从而使仿真过程更加顺利地进行.
In HLA time management the value of lookahead is set by the user during the simulation execution process. In the actual simulation system looking for the fit lookahead value is more difficult. In order to improve the efficiency and the effectiveness of the simulation running more, the adjustment and configuration of lookahead is studied. The original purpose of introducing lookahead is to avoid deadlock, but deadlock will be resulted when lookahead equals zero. If these laws are well known, the deadlock can be avoided efficiently, and the simulation process will go on freely.
