Time Measurement by Sequencer

Time can be measured using the sequencer. A time measurement timer called the
emulation timer is used for this purpose. When branching is made from a specified level
to another specified level, a timer value is specified. Up to two emulation timer values can
be fetched. This function is called the timer latch function.

Time Measurement by Sequencer

The time duration between two given points in a complex program flow can be measured using the timer

latch function.

The timing for the timer latch can be set using the SET SEQUENCE command; the latched timer values can

be displayed using the SHOW SEQUENCE command.

When a program starts execution, the emulation timer is initialized and then starts counting. Select either 1

μs

or 100 ns as the minimum measurement unit for the emulation timer. Set the measurement unit using the SET

TIMESCALE command.

When 1

μs is selected, the maximum measured time is about 70 minutes; when 100 ns is selected, the

maximum measured time is about 7 minutes. If the timer overflows during measurement, a warning message

is displayed when the timer value is displayed using the SHOW SEQUENCE command.
