Match/Action & Complex Matches
Die hoch entwickelte Match/Aktion System bietet Entwicklern die Möglichkeit komplexe Multi-State-Matches für USB 2.0 Anwendungen zu erstellen. Wenn eine Übereinstimmung auftritt, kann die Match Einheit eine oder mehrere definierte Aktionen auslösen, wie Erfassen, Zuordnen eines externes Ausgangs, Herausfiltern passender Daten oder Anweisung in einen anderen Zustand zu gehen.

| Match Units | The fundamental building block of the advanced match/action system is a match unit. There six matches available for the user: four data matches, one event match, and one timer match. A USB 2.0 data match unit can match specific packet types and/or patterns with optional matching prefix (IN, OUT, or SETUP) and handshake (ACK, NAK, NYET, etc.) parameters. An event match unit can match bus events such as digital inputs. Lastly, a timer match will match after a set interval of time. Match units also have built in counters that can control when an action occurs. |
| Multiple States | The advanced matching system provides the user with up to 8 states, with each state defining one or more match units. Unlike other analyzers on the market, the states are non-sequential and can even be defined to go to itself. This flexibility allows the user to build a state machine to track USB 2.0 behavior with the Beagle USB 480 Power analyzer. Additionally, the order of match units is significant because if multiple matches occur at the same time, priority is given to the action of the first match unit. |

| Advanced multi-state matching | An advanced match has been setup with three states. The first state matches for different data patterns in the downstream direction. Depending on the pattern, a match will branch to either state 2 or 3 to create a multi-state match to trigger the capture. |
| USB 2.0 data match unit | The Data Match Configuration for a Packet type enables users to match on specific PIDs, data patterns, data properties, and CRC conditions for USB 2.0. Additionally, a packet prefix and handshake can be selected to indicate a desired matching transaction on the bus. |
