I have run the JTAG VIP demo in sv lang . while running the demo the design browser shows : the top tb file , jtag if , sys hierarchy , packages and ovm top levels .
1)what is the SYS hierarchy ? when we close the simvision console after creating .shm and try to load the .shm it does not shows the sys hier that time while for other demos ex: apb it shows intf as well as ovm_hier ?
2)also there is some problem in loading transactions which are under the sys->master_agent->monitor transations. i mean the transactions are not created. why the master and slave agents are under sys ?
3)finally for understanding the JTAG environment what transactions we have to check apart from top jtag signals and intf signals ?
Please help me out with my doubts as i am new to verification .
