+This file describes the directives and concepts tested by this test set.
+
+test set name: spedfsched01
+
+directives:
+ ex_init, ex_start, t_create, t_start, tm_tick, i_return, t_ident,
+ tm_set, tm_get, tm_wkafter
+
+concepts:
+
+This test is identical to sp01 but for EDF-based scheduling:
+
+ a. Verifies system can create and start both the executive's system
+ initialization and idle task.
+
+ b. Verifies executive can swap between three application tasks at the
+ same priority and the executive's internal idle task.
+
+ c. Verifies can print strings to the CRT on port 2 of the mvme136 board
+ using Print and Println in the board support package.
+
+ d. Verifies interrupt handler can handle a task switch from an interrupt
+ as specified with the i_return directive.
+
+ e. Verifies executive initialization performed correctly.
+
+ f. Verifies the executive trap handler except for the halt function.
+
+ g. Verifies that a task can get the task identification number of itself.
+
+ h. Verifies implementation of SuperCore TOD_MILLISECONDS_TO_TICKS. Normal
+ computation in applications is via a macro at the Classic API level.
+
+output:
+ "TA1" is printed once every 5 seconds. "TA2" is printed once
+ every 10 seconds. "TA3" is printed once every 15 seconds.
