Generic Message Processor Example

Here is a simple IPC message processor, built using the phoIPC sublist processing functions. The message processor requires the following five arguments:

• cv: Cellview in which the objects specified in the message need to be created.
• msg: Message containing the sublists. It must be formatted as specified in the Standard phoIPC Message Format.
• designIntentLayer: Default waveguide layer.
• dropPort: Boolean value, if set to nil, the electrical or optical port is not created. dropPort can be used when creating a hierarchical Pcell, where the lower-level ports are not used by the tool, and therefore, can be skipped (or dropped) for improved performance.
• portMap: List representing the port mapping information.
  

  procedure( myMsgProc( cv msg designIntentLayer dropPorts portMap)

  let( (polygons ports markers)

  ; get the relevant parts from the server message

  polygons = car(msg)

  ports = cadr(msg)

  markers = caddr(msg)

  ; send each one to the appropriate default processor

  phoIPCProcessShapes( cv polygons portMap)

  phoIPCProcessPorts( cv ports portMap)

  phoIPCProcessMarkers(cv markers "My IPC Tool")

  )

  )

Let us consider the following example that demonstrates the use of some functions described in this chapter. The code snippet displayed below is part of a Pcell code block and it illustrates at a high-level how the various phoIPC functions can be used.

; make sure the communication is open for the "phoIPCSample" processor

when( phoIPCServerCheck("phoIPCSample" pcCellView)

The server is started and working.

• Modify the parameters, as required.
• Prepare the call to the IPC server.

msg = 

Calls the IPC server and gets the message back.

portMap =

Creates a portMap, if required.

phoIPCProcessServerMessage(pcCellView "waveguide" msg nil portMap)

) ; done

Creates the objects in the submaster.
