Test of the ALICE DDL: Test setups and Test of ALICE DDL Integration to ALICE TPC test system

<P>Presentation made at the 4th Workshop on Electronics for LHC Experiments, INFN Rome, 21-25 September 1998.<P>The Detector Data Link (DDL) has been developed to constitute a standard interface between the ALICE sub-detectors and the DAQ system.<P>In this paper we present the test environment and the application software library made for supporting the DDL development and its integration into the ALICE detector system. <P>The test setups contain VME64 crates, MVME processor cards, a VMETRO analyser, a logic-analyser and Read-out-Receiver (RORC) andDestination-Interface-Unit (DIU) cards. They made possible to measure the maximum throughput of the full read-out chain and also to measurethe transmission latencies. They support the functional and long-term stability tests as well.
