Adding a variable to control the number of packets to be created, class generator ( because the same mailbox will be shared across generator and driver)Ĥ. Getting the Mailbox handle from the env class.Mailbox is used to send the randomized transaction to Driver, If( !trans.randomize() ) $fatal("Gen:: trans randomization failed") ģ. main task, generates(create and randomizes) the packets and puts into mailbox Randomize the transaction class, class generator Declare the transaction class handle, class generator Ģ. Generating the stimulus by randomizing the transaction classġ.constaint, to generate any one among write and read Either write or read operation will be performed at once, so wr_en or rd_en is generated by adding constraint. To generate the random stimulus, declare the fields as rand. Below are the steps to write a transaction classġ.So, the first step is to declare the Fields‘ in the transaction class.

In this implementation, the serial bits are shifted into place. The previous implementation used a counter to indicate the bit of the output that was set when a new serial bit was read. This design performs the same function as the previous one but uses a different algorithm to do the conversion. This example describes another implementation of the serial-to- parallel converter in the last example.
