DVP and EMU2 (HDS2) emulator features UM0036
238/385 Doc ID 7705 Rev 11
The EMU2 Emulator version and the DVP versions are slightly different in the way they use
hardware events:
● For the EMU2 emulators, hardware events are used to control the trigger outputs
(OUT1 or OUT2).
● For the DVP2 and DVP3 emulators, there are three types of hardware events that can
be used to control either the trace recording or the trigger output:
– Event On (EVT_ON): The address where the event begins.
– Event Off (EVT_OFF): The address where the event ends.
– Event Hit (EVT_HIT): The event is active for the cycle in which one particular
address is accessed.
● For the DVP1 emulators, there are only two types of hardware event, and these
always control the output trigger:
– FORCE_HIGH: Forces the output trigger signal to one.
– FORCE_LOW: Forces the output trigger signal to zero.
This section provides hardware event information that is common to DVP and EMU2
emulators, including:
● The hardware event window and contextual menu
● Adding a hardware event
For more information about how to control the triggers and trace on your DVP emulator, refer
to Section 8.7 on page 255.
