R

and the status for that channel. This sends the status and the channel to the stimulus module for transmission to the core. The stimulus module ensures that the status is sent in the correct location of the calendar sequence.

Calendar Sequence Files (Sink and Source)

The snk_calendar.dat and src_calendar.dat files are used to define the order that status is sent on the SPI-4.2 Interface. The number of lines in a file is equal to the length of the calendar sequence (SnkCalendar_Len + 1 and SrcCalendar_Len +1). Each line of the file represents an 8-bit calendar entry in hexadecimal format. For example, a calendar with a length of five and a sequence of <channel 0, channel 1, channel 0, channel 2, channel 3> can be generated by the following format:

00

01

00

02

03

File names are defined in the test case package, and can be changed if desired.
