The Abaco Systems / Condor Engineering CNIC-A2P is a dual-port ARINC 664 Part 7 PMC interface engineered for avionics and aerospace test, monitoring, and traffic generation. The card configures as either a single dual-redundant AFDX interface or two independent high-performance ports, each operating at 10/100 MHz full-duplex. Its proprietary pipeline architecture employs parallel controllers and efficient DMA transfers to achieve maximum packet throughput while bypassing CPU-based interface bottlenecks.
The CNIC-A2P delivers simultaneous real-time traffic generation on both ports with advanced transmission scheduling and link-level error injection. Every incoming packet receives a 64-bit timestamp with 20 nanosecond resolution for precise temporal correlation. Integrated IRIG-B receiver/generator capability enables synchronization to external time sources or between multiple CNIC boards, critical for multi-unit test systems.
Full-bandwidth AFDX/ARINC 664 Part 7 protocol monitoring captures all frame and header data with comprehensive link and protocol-level statistics. Error detection and injection, built-in test (BIT) features, and I/O trigger support round out the diagnostic toolkit. The FPGA-based architecture ensures deterministic performance independent of host processor load.
Software integration spans multiple paradigms: high-level AFDX API, low-level raw frame-based API, and .NET integration libraries support diverse development environments. Flexible packet capture API, XML configuration format, and integrated log file format streamline integration into automated test workflows. Berkeley packet filter capabilities enable sophisticated traffic filtering and capture rules.
