Click to expand...


first compile the file with cover option
b–Collect branch statistics.
c–Collect condition statistics.
e–Collect expression statistics.
s–Collect statement statistics. Default.
t–Collect toggle statistics. Cannot be used if ’x’ is specified.
x–Collect extended toggle statistics
Cannot be used if ’t’ is specified(Toggle Coverage)

Code: 
vlog -cover  bcs work.test_bench
start vsim with coverage switch
Eg
Code: 
vsim -coverage work.test_bench

ok thank you very much.....
Can u please tell me how to check the generated coverage report..?
 

once you have compiled the file with cover options like bcs
then run the simulation with coverage option

Eg
Code: 
vlog -cover bcs *.v
# QuestaSim vlog 10.0b Compiler 2011.05 May  5 2011
# -- Compiling module counter
# -- Compiling module test_counter
# 
# Top level modules:
# 	test_counter
vsim -coverage test_counter
# vsim -coverage test_counter 
# ** Note: (vsim-3812) Design is being optimized...
# Loading work.test_counter(fast)
run 20000

now you could see a window

like this Local coverage Aggregation



undock that window



Here you can see the code coverage statistics
 
hi all, can you explain some method to merge random test case coverage with sv language?
