AN-6130PCIe
MIL-STD 1553 PCIe Card
Evaluation Card Users Guide
March 4, 2015
Introduction:
The Holt HI-6130 PCIe MIL-STD-1553 is a PC interface card designed to interface the Holt HI-6130 MIL-
STD-1553 multi-terminal to a single lane x1, x4/8 or x16 PCI Express (PCIe) 1.1 slot on a PC running
Windows 7. The HI-6130 is a single supply 3.3V rail BC/MT/RT1/RT2 Multi-Terminal device for MIL-STD-
1553 dual redundant bus communications. The card is bundled with the Holt high-level API software
library and two demo programs. The two demo projects provided on the included CD-ROM demonstrate
the basic features of the HI-6130 and the Holt API software library. The demo card and software can be
used as starting point for any new custom design.

LED 8 flashes when a read occurs and LED 9 flashes when a write occurs. Press “q” to quit. This is the end of the Quick Start Guide section. HOLT INTEGRATED CIRCUITS...
  • Page 6 AN-6130PCIe Hardware The Holt HI-6130 PCIe interface card consists of three main IC components shown below in the Block Diagram. The PEX 8311 is a PCI Express-to-Generic Local Bus bridge and provides the interface between the PCIe slot and the local bus (LB). A CPLD translates the LB signals into CSn, RDn and WRn strobe signals for the HI-6130 timings.
  • Page 7 SDK and RDK reference board design including drivers, documentation and demo software is available from PLX. This PLX RDK was used as the basis for the Holt card. An EEPROM (U6) contains configuration data which the PEX8311 latches in at power up to configure the LB for the target hardware base address space, data bus width, and the number of wait states.

  • Page 10 A large portion of the CPLD is unused with sufficient room for custom expansion. A Lattice USB programming cable PN: PN-USBN-2A is required to reprogram the CPLD but is NOT provided by Holt. This is only needed if the end user wishes to alter the Verilog code and reprogram the CPLD. Using the Lattice Diamond CPLD development software is beyond the scope of this document but many tutorials are built into Lattice Diamond software which is available for download from their website.

  • Page 13 PLX SDK installation To modify the demo programs the PLX SDK must first be installed so that the Holt projects can be added to the SDK samples folder. To develop custom software applications for this card, the SDK from PLX is required.
  • Page 14 Follow these steps to install the demo project into the PLX SDK Samples folder: Install the PLX SDK. Locate the zipped Holt demo project “PCIe 6130 test.zip” on the CD-ROM and unzip this project folder into the C:\Plx\PlxSdk\Samples folder. Use this directory structure because some PLX files reference other files in these directories.

  • Page 16 HI-6130 and the inputs are used to read HI-6130 status and DIP switches. The Holt demo code includes several functions to read and write to the HI-6130 memory space, latches and input status buffers. The API functions are located in HI6130.c. These functions use a PLX API to access the LB with either “PlxPci_PciBarSpaceRead(…)”...
  • Page 17 AN-6130PCIe Select the Holt PCIe card from the Command menu (or press the green icon button on the left) and select the device with Dev ID = 9056 and Ven ID = 10B5. The PEX8311 consists internally of a PEX8111 and a PCI9056.
  • Page 18 PLX. For detailed information on these parameters and the PLX API’s refer to the PLX SDK user’s guide and data sheet on the PEX8311. For the Holt card, there is no need to alter any of these values.
  • Page 19 Output window which can be ignored but there should be no critical errors preventing the debugger from running the project. A menu will be displayed showing sets of numbers 1 though x. The Holt card typically appears as the first item, #1 with “9056 10b5” [b:xx s:xx f:xx]. Enter “1” and press Enter.

  • Page 22 B. The waveform below shows the HI-6130 RT1 responding to BC command with matching address. The bus output should be terminated with 70 ohms and the RT response data shows same amplitude as BC since RT transmission occurs on the same bus stub as BC transmission. HOLT INTEGRATED CIRCUITS...

  • Page 30 MIL-STD-1553. ARINC 429 Holt has several ARINC 429 protocol receivers and transmitters that could be interfaced to the PCIe local bus (LB) and CPLD on this design. All the same hardware and software techniques would apply. The devices that have a parallel interface would be the easiest to interface on the LB.

  • Page 31: Power Supplies

    PCIe current draw from the 12V rail cannot exceed 0.5A for x1 cards, 2.1A for x4/x8 cards or 4.4A for x16 cards. For a PCIe x1 card (like the Holt example) the worst-case available power from the slot 12V rail is (12V minus 8%) x .5A = 5.52W.

    PCB layout considerations The PLX data book and hardware checklist should be closely followed for the PCIe high speed bus signals. Review the Holt AN-550 for PCB layout guidelines for the transformers and decoupling capacitors for the HI-6120, HI-6130 and HI-6140.
  • Page 33 The Holt HI-6130 PCIe low profile card reference design demonstrates how to interface the HI-6130 MIL- STD-1553 multi-terminal to a 1 lane (x1) PCIe bus. A Holt high-level API software library is provided and demonstrated in the demo software. All the design files are included on the CD-ROM, including the Orcad schematics, two software demo projects and Verilog source for the CPLD with other related documents to enable rapid custom development.
