这段代码定义了四个指针变量和两个函数块数组变量。其中,P_Sys指向DUT00_Sys变量,P_Pump指向DUT01_Pump变量,P_EV指向DUT02_EV变量。FB_Pump是一个长度为10的函数块数组,每个元素都是一个FB01_Pump函数块。FB_EV是一个长度为10的函数块数组,每个元素都是一个FB02_EV函数块。Link和SIM都是布尔类型的变量。

This code declares variables and data types using a programming language syntax. Here is a breakdown of what each line means:
- P_Sys: POINTER TO DUT00_Sys; This declares a pointer variable named P_Sys that will point to an instance of the data type DUT00_Sys.
- P_Pump: POINTER TO DUT01_Pump; This declares a pointer variable named P_Pump that will point to an instance of the data type DUT01_Pump.
- P_EV: POINTER TO DUT02_EV; This declares a pointer variable named P_EV that will point to an instance of the data type DUT02_EV.
- FB_Pump: ARRAY[0..9] OF FB01_Pump; This declares an array variable named FB_Pump that can store 10 instances of the data type FB01_Pump.
- FB_EV: ARRAY[0..9] OF FB02_EV; This declares an array variable named FB_EV that can store 10 instances of the data type FB02_EV.
- Link: BOOL; This declares a Boolean variable named Link that can store either a true or false value.
- SIM: BOOL; This declares another Boolean variable named SIM that can store either a true or false value.
Without more context or information about the programming language used, it's difficult to provide more specific details about what this code does.
uvm_warnig:[manage_objections]time out due to bus inactivity,drop all object
这个警告信息来自于UVM(Universal Verification Methodology)库,它是一种通用的验证方法学,用于验证硬件设计。此警告表示由于总线不活跃,UVM无法管理反驳。在验证中,当需要检测某些信号是否被正确处理时,通常会使用反驳机制。反驳机制是一种通过向DUT(设计单元)发出不正确的信号,然后验证环境能够检测到并发出警告的测试技术。
当总线变得不活跃时,UVM无法像平常一样管理反驳,因此UVM将删除所有的对象。总线变得不活跃可能是因为测试用例无法正确的发送数据,或者DUT无法处理请求,导致总线长时间不活跃,超时并且全部对象都被删除。
为了解决这个问题,我们需要检查测试用例中是否存在错误,并调整DUT的响应时间。此外,也可以更改UVM设置,以便增加超时时间,以便在总线超时之前,可以给DUT足够的响应时间。这将有助于确保反驳机制可以正常工作,并在需要时发出警告信息。
