doooogo Posted September 21, 2011 Report Share Posted September 21, 2011 Hi, I have a memory, its width is 32, and size is 1024. My system bus width is 16. The UVM version is 1.1. I call the burst_write() function with UVM_FRONTDOOR, and UVM gives the error message: Cannot burst a 32-bit memory through a narrower data path(16 bytes). First, I believe that the unit following "16" is bits not bytes, this is UVM's bug. Second, I don't understand why UVM doesn't allow this kind of burst operation? I have checked the code, that the uvm_reg_map's do_bus_write function supports this kind of burst operation. The only problem is that uvm_mem::Xcheck_accessX function's line 1835-1841 don't permit this kind of burst operatiion. Is this intend or a bug？ Quote Link to comment Share on other sites More sharing options...
