Fatal error reported during simulation. Cannot run ‘fcover’ command. Please look above output for the fatal error message(s).
The error pops up only when the following line of the code is uncommented: cov_group.sample();
The error closely points to driver where the drive task is defined:
task drive(REQ req, RSP rsp);
`uvm_info("DEBUG", {"\n", req.sprint()}, UVM_FULL);
`uvm_info("ITEM", {"\n", req.sprint()}, UVM_NONE);
// set signals according to 'req'
// capture any output (including input) in 'rsp'
@(posedge vif.clk_i);
vif.rstn = req.rstn;
endtask: drive
I dont have good understand about req and rsp. Maybe something wrong with driving the signals?
Thank you and Regards,
