Eldo Control Language
Task Definition
A task (in other words, the sequence of statements inside the task) is never executed until it is
called. There is no such thing as a predefined automatically-executed “main” task as in C.
A task may be called in either of the following ways:
• From within another task (in which case the calling syntax uses parenthesis and commaseparated
arguments – similar to classical programming).
• From the netlist using a . command, which then appears as an
additional Eldo command in a regular Eldo netlist (a sequence of .
calls from the .cir netlist is supported).
A task may call another task defined in the same netlist/file as itself, or in another netlist/file (as
long as it is included in the main netlist with a .INCLUDE or a .LIB command).
Note
The Eldo Control Language is case-sensitive.
