摘　　要：HGTMS板卡需要用到多个复杂芯片,而每个芯片都有具体的上电时序。本文根据各上电时序要求,使用EPLD POWR1220AT8控制各电源上电时序和电压值监控,从而保障板卡可以正常启动。本设计具有普遍性,在各种板卡设计中都可以使用。Several complex chips need to be use for HGTMS card. Each chip has the special power on sequence. According to the power on sequence, EPLD POWER1220AT8 is used to control the power on timing and voltage monitoring, so as to make sure the board can start up successful. This design is in common use in other systems for power on sequence and voltage monitor.
