19.3 USING FILE STIMULUS

MPLAB SIM triggers changes to pin and register values specified in a file by using File

Stimulus. These files specify values that will be sent to a pin or register when a trigger

is fired. This trigger may be a cycle count for pins or a program memory address for

registers.

19.3.1 Creating/Editing File Stimulus

Select Debugger>Stimulus Controller and then click the File Stimulus tab. A File

Stimulus file is composed of one or more Synchronous Stimulus files. A Synchronous

Stimulus file contains information on triggers used for applying stimulus to either a pin

or register. Register stimulus is specified in a Register Stimulus file.

• Creating/Editing a File Stimulus File (.fsti)

• Creating/Editing a Synchronous Stimulus File (.ssti)

• Creating/Editing a Register Stimulus File (.rsti)

Note 1: Changing stimulus files outside the Stimulus dialog is NOT

recommended.

2: If you have already set pin stimulus on a port pin, you will not be able to

inject stimulus into that pin or corresponding register using file stimulus.
