the pre_body() override, the use of the default value constraints is turned off. Inthe post_randomize() override, the randomized value is printed out so that SNR values can be related to whether pulses are detected or not. Ituses a class utility function fixed2real to give a friendly...

1. 事务 tansaction 事务 tansaction 是一系列具有一定关系和功能的数据集合。 简单来说,一个tansaction就是把具有某一特定功能的一组信息封装在一起而成为的一个类; 事务是UVM平台中信息交互的基本单元 1.1. 从uvm_sequence_item扩展事务 1.2.
