GCL Rule Execution Sequence
There are 16 logic rules on one ADAM-6000 module. Refer to the figure
7.22 below to see the execution flow for one cycle. You can see there are
3 groups for one cycle: Input Condition + Logic, Execution, and Out-
put. All the Input Condition + Logic stages of rules which are enabled
will execute sequentially first. Then, all the Execution stages of rules
which are enabled will be executed in sequence. At the end, all Output
stages of rules which are enabled will be executed in order.
For some advanced applications, you may combine different rules
together by Logic Cascade architecture (described in section 7.4.1). For
example, the output of rule 1 is connected to the input of rule 2, by
assigning to the same internal flag. Based on the execution flow men-
tioned above, the Input Condition + Logic, Execution and Output
stages of rule 1 will be executed sequentially. Therefore, the output of
rule 1 will be updated at the last stage (Output stage) in the first cycle,
and the input of rule 2 can detect the change of output of rule 1 in the next
cycle.
