TYPES OF CODE COVERAGE




There are a number of coverage criteria, they are:

Statement coverage /line coverage
Block/segment coverage
Conditional coverage
Branch coverage
Toggle coverage
Path coverage
Fsm coverage

The following example is considered while explaining code coverage types in further sections.



EXAMPLE
1
2 module dut();
3 reg a,b,c,d,e,f;
4
5 initial
6 begin
7 #5 a = 0;
8 #5 a = 1;
9 end
10
11 always @(posedge a)
12 begin
13 c = b && a;
14 if(c && f)
15 b = e;
16 else
17 e = b;
18
19 case(c)
20 1:f = 1;
21 0:f = 0;
22 default : f = 0;
23 endcase
24
25 end
26 endmodule
