In the pre_body() override, the use of the default value constraints is turned off. In the post_randomize() override, the randomized value is printed out so that SNR values can be related to whether pulses are detected or not. It uses a class utility function fixed2real to give a frie...
bitrerandomize=0) The send_request function may only be called after a wait_for_grant call. This call will send the request item to the sequencer, which will forward it to the driver. If the rerandomize bit is set, the item will be randomized before being sent to the driver. wait_for...

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.
