parameters:
processingDelay = rteProcessingDelay,
buffersize = rteBuffersize;
gatesizes:
input[numOfPorts+1],
output[numOfPorts+1];
portIf: DataLink[numOfPorts]
parameters:
retryCount = 5,
windowSize = 2;
connections:
for i=0..numOfPorts-1 do
routing.output[i] --> portIf[i].fromHigherLayer;
routing.input[i] <-- portIf[i].toHigherLayer;
portIf[i].toPort --> outputPorts[i];
portIf[i].fromPort <-- inputPorts[i];
endfor;
routing.output[numOfPorts] --> localUser.input;
routing.input[numOfPorts] <-- localUser.output;

Example 2: Chain
For example, one can create a chain of modules like this:
module Chain
parameters: count: const;
submodules:
node : Node [count]
gatesizes:
in[2], out[2];
gatesizes if index==0 || index==count-1:
in[1], out[1];
connections:
for i = 0..count-2 do
node[i].out[i!=0 ? 1 : 0] --> node[i+1].in[0];
node[i].in[i!=0 ? 1 : 0] <-- node[i+1].out[0];
endfor;
endmodule
Example 3: Binary Tree
One can use conditional connections to build a binary tree. The following NED code loops
through all possible node pairs, and creates the connections needed for a binary tree.
simple BinaryTreeNode
gates:
in: fromupper;
out: downleft;
out: downright;
endsimple
