647 Microcontrollers Debugger Manual
• The identifiers declared in IdDeclaration are stored in a table of identifiers and can
be also used in Expression.
• If “#” is specified, the time is absolute: it is the number of cycles since the Full Chip
Simulation was started.
• If “+” is specified, the time is relative to the previous time specification.
• If nothing is specified, time is the number of cycles since execution of the
Stimulation file.
• If size is omitted, the default size is byte (B).
• The periodical event is sent for the first time at initial time + start + time specified in
periodical timed event.
•In the PerTimedEvent declaration, the “+” is optional. If specified or not, the
following time is interpreted exactly the same way.
• The periodical events are not displayed in the stimulation screen.
Electrical Signal Generators and Signals
Application to Device Pins
Signal IO Component
This Signal IO is the first implementation of a Signal Generator reading, in real
debugger time, a file describing (electrical) levels. Levels are applied and available at a
virtual IO pin called SignalPin as float value.
Levels are programmed one after the other during the debugger internal Event queue of
the FCS.
If levels duration value is less than cycle time or smaller than cycles, undersampling is
performed in the signal file.
You can run up to 16 Signal Generators at the same time.
