Hi, I am getting the above error ,can any one suggest reason and solution for this?
there are two sequences written for wishbone interface-> one is the initial sequence and other is end sequence
the task body codes for both are as below:
virtual task body();
uvm_info("wishbone initial sequence","came inside the wishbone initial sequence body",UVM_LOW); // Write to the Configuration register and enable transmission of frames uvm_do_with(req, { xt_n==WRITE; xt_addr==8’h00; xt_data==32’h1; } );
// Write to the Interrupt Mask register and enable all the interrupts
`uvm_do_with(req, { xt_n==WRITE; xt_addr==8’h10; xt_data==32’hFFFF_FFFF; } );
endtask //body
virtual task body();
uvm_info("wishbone ending sequence","came inside the wishbone ending sequence body",UVM_LOW); // Read the Configuration register 0 uvm_do_with(req, { xt_n==READ; xt_addr==8’h00; } );
// Read the Interrupt Pending register
uvm_do_with(req, { xt_n==READ; xt_addr==8'h08; } ); // Read the Interrupt Status register uvm_do_with(req, { xt_n==READ; xt_addr==8’h0C; } );
// Read the Interrupt Mask register
`uvm_do_with(req, { xt_n==READ; xt_addr==8’h10; } );
endtask // body
