rising |
A condition defined with a rising edge shall return true at discrete time t if its logical expression is true at discrete time t and its logical expression was false at discrete time t-ts, where ts is the simulation sampling time.
|
falling |
A condition defined with a falling edge shall return true at discrete time t if its logical expression is false at discrete time t and its logical expression was true at discrete time t-ts, where ts is the simulation sampling time.
|
risingOrFalling |
A condition defined with a 'risingOrFalling' edge shall return true at discrete time t if its logical expression is true at discrete time t and its logical expression was false at discrete time t-ts OR if its logical expression is false at discrete time t and its logical expression was true at discrete time t-ts. ts is the simulation sampling time.
|
none |
A condition defined with a 'none' edge shall return true at discrete time t if its logical expression is true at discrete time t.
