§ Identifying Coverage Types

1. coverage types

• code coverage : block, branch, expression, toggle
  • block, branch : 어떤 코드가 수행되었나 ?
  • expression : 왜 그 코드가 수행되었나 ?
• functional coverage : data oriented, control oriented
  • data oriented : 어떤 data가 assign 되었나 ?
  • control oriented : assertion base

2. code coverage

• 설계한 코드를 얼마나 빼먹지 않고 잘 test 하는지를 확인
• measure : code block execution, expression term states

§ Defining Data Coverage

1. Code coverage versus Functional coverage

• code coverage : less difficult to set up - more difficult to analyze
• functional coverage : more difficult to set up - less difficult to analyze
  • instrumented by user. user specifies scenarios, corner cases, protocols, etc.

2. Data-oriented functional coverage : focus on DESIGN DATA

• 어떤 값이, 어떤 조합으로, 그리고 그 값이 어떤 transition 이 발생했는지?
• data-oriented functional coverage adds value beyond code coverage. +
