Counter_Loop_Port

Full Library / Math Operator / Counter / Counter_Loop_Port
Block Name: Counter_Loop_Port

Code File Location: VisualSim/actor/lib/Counter_Loop_Port

Block Overview

• This block contains a counter that is incremented or decremented, whenever a value is received on the ready_input port. The "ready_input" triggers the loop increment (or decrement) and outputs the loop counter value to the "counter_output", unless the "final_input" value is exceeded in either a positive, or negative direction. Once the "final_input" value is exceeded, then the "done_output" is activated. The initial counter, final counter and increment (or decrement) counter values are sent by initializing this block with values on the three input ports: initial_input, final_input, increment_input. When done_output is activated, the internal counter is reset to the initial value.

initial_input

public TypedIOPort initial_input

• Initial counter state input via "initial_input" port. Type can be integer, long, or double. The inital counter value is also output on the loop_index_output port.
• 
  

final_input

public TypedIOPort final_input

• Final counter state input via "final_input" port. Type can be integer, long, or double.
• 
  

increment_input

public TypedIOPort increment_input

• Specifies the positive or negative value that the counter must be incremented by whenever a trgger is received on the ready_input port.Type can be integer, long, or double.
• 
  

ready_input

public TypedIOPort ready_input

• "ready_input" input increments counter from initial counter state. If the three inputs, initial, final, and increment have not been set prior to triggering the "ready_input", then an exception is set.
• 
  

counter_output

public TypedIOPort loop_index_output

• "loop_index_output" port sends out the current state of the loop counter. The first output appears when the "initial_input" is set. Subsequent outputs appear when the "ready_input" is triggered, which increment the loop counter.
• 
  

done_output

public TypedIOPort done_output

• "done_output" fires when the counter reaches the final counter value instead of the "loop_index_output".
