DVE 如何查看代码覆盖率和功能覆盖率

#sv and DUT paths
RTL = ./router.v
SVTB = ./router_top.sv ./router_if.sv ./router_tb_pkg.sv ./router_tb.sv 
SEED = 1


#code coverage command
CM = -cm line+cond+fsm+branch+tgl
CM_NAME = -cm_name simv
CM_DIR = -cm_dir ./covdir.vdb

compile:
	 vcs  -l vcs.log -sverilog -full64  -debug_access+all \
   $(SVTB) $(RTL) \
	 -top router_top \
	 ${CM} \
	 ${CM_NAME} \
	 ${CM_DIR}



rung:
	./simv ${CM}  -gui -l run.log
	


cov:
	dve -full64 -covdir *.vdb &
