Freescale Semiconductor Microcontrollers Stimulation Input File Syntax

ColdFire V1 Full Chip Simulation Connection
True Time I/O Stimulation
645 Microcontrollers Debugger Manual
This line of code reads pbits (three bits in Leds. Port_Register), increments this
value and writes it to b. The + in front of the time marker refers to the time relative to the
last encountered time value in the Stimulation file.
PERIODICAL 100000, 10:
This line of code executes the following block 10 times:
10000 a = 128;
30000 RAISE 7, 3, "test_interrupt";
This starts execution 100,000 cycles after the start of the simulation.
10000 a = 128;
This line of code assigns 128 to a, 10000 cycles after each start of the periodic event.
30000 RAISE 7, 3, "test_interrupt";
This line of code raises an interrupt with priority 3 with vector number 7, 40000 cycles
after each start of the periodic event. The time specification in the PERIODICAL loop is
always relative, so 30000 means +30000. The raised interrupt has the name
test_interrupt. This name is not important for the interrupt functionality.
END
This line of code is the end of the periodic block. The block loops again after finishing, so
the loop restarts after 10000 + 30000 = 40000 cycles.
1000000 RAISE 7, 3, "test_interrupt";
This line of code raises the interrupt for the last time. This instruction marks the
terminating point of the Stimulation, if there are no pending periodical events left.
Stimulation Input File Syntax
The following listing shows the EBNF input file syntax.
Listing 28.10 EBNF
StimulationFile = { IdDeclaration | TimedEvent | PeriodicEvent }.
IdDeclaration = “def” ObjectId “=” ObjectField “;”.
ObjectField = ObjectSpec [ “[” BitRange “]” ].
BitRange = StartBit “:” NoOfBits.
