Zijay Posted August 30, 2012 Report Share Posted August 30, 2012 Hi, I'm now building a uvm_mem model and try the frontdoor access with burst_write and burst_read, all works fine. And I tried to test the backdoor access with peek/poke, after searching for some information, it seems to have uvm_reg_backdoor extension set to uvm_mem first, then I need to implement the virtual task/func "write" and "read_func" in child class of uvm_reg_backdoor. I confused that how to implement those two overloaded "write" and "read_func" ? Seems that should directly write to and read from uvm_mem object, but should they still use frontdoor access "read/write" APIs of uvm_mem or the backdoor way (still peek or poke) ? I ever tried the frontdoor access but it then call to "reg2bus" again, and the simulation is hanged in backdoor way. Can anyone give me some hints or examples ? Thanks in advance !
