5 CC-PC Gluecard Application and User's Guide 1 Introduction The CC-PC and the gluecard are used to control electronics boards used in the counting room (on the good side of the wall, away from radi at i o n ). This document tries to summarise hardware issues arising when designing a board around these two components. It is a summary of experience gained in designing proto-type and evaluation boards and of the following documents: and In the following it is assumed that the CC-PC is used in conjunction with the gluecard. Introduction page 1
6 2 Using the CC-PC in a board design In this chapter the design guide-lines for using a CC-PC and the gluecard in a board design are detailed. The carrier or mother board is simply referred to as the board in the following text. 2.1 Gluecard Feature The gluecard accompanying the CC-PC was designed by the Genoa section of Istituto Nazionale di Fisica Nucleare. A block diagram of the gluecard is shown in Figure 1. Figure 1 Block diagram of the gluecard Heart pieces of the module is a PCI9030 from PLX technologies [2] and a small FPGA (XCS05XL) from XILINX ([3] ). The PCI9030 acts as a bridge between the PCI bus of the CC-PC and a simpler parallel bus while the FPGA interfaces the I2C and JTAG controllers to the parallel bus of the PCI9030. The parallel bus is gated by bus switches towards the carrier card such that the gluecard can be isolated from the main board. This is useful to prevent interference of the main board s activity when the CC-PC is rebooting. It was also required that the gluecard should provide 3 JTAG master ports and 4 I2C master ports. The JTAG master ports are provided by a 3-port JTAG bridge (SCANSTA111) by National Semiconductors ([4] ) which is driven by a JTAG controller (SN74LVT8980A) from Texas Instruments ([5] ). page 2 Using the CC-PC in a board design
7 The I2C buses are provided through an I2C hub (PCA9516) driven by an I2C controller (PCF8584) both from Philips ([6] ). Programming of the XILINX FPGA is performed through the parallel port of the CC-P C. The MAX211 RS232 line driver/receiver from TI provided RS232-compatible signals that can be directly connected to a serial connector on the c arrier board. 2.2 PCB Guidelines Integrating a CC -PC to a board design must follow some general guidelines, which are listed in the following [1] : 10 x 100 nf filtering capacitors should be placed on the 5V line as close as possible to the power pins. Separate Power and ground planes should be used. Even though also 5V equipment is in principle supported by the CC-PC, only 3.3V equipment should be used. 5 to 10 x nf and 2 x 100 µf filtering capacitors should be places as near as possible to the 3.3 V power pins. Pull-up resistors should be of 10K type. If buffers are needed, it s recommended to use 74HC/HCT245/244, or 74ABT245/244. The CC-PC unused pins can be left open. It is not recommended to place components underneath the CC -P C. P C I-CLOCK should not be shared with another load. All clocks should be routed on internal layers, with minimum vias usage. Board impedance should be 55? ± 15 %. All clocks should have 1:2 width-to-space ratio. Using the CC-PC in a board design page 3

Component side on the left and connector side on the right CC-PC and Gluecard relative positioning Figure 6 shows the relative positioning of the CC -PC and the gluecard on a carrier board. The gluecard is designed with the assumption that the connector J2* of the gluecard is a 1-1 image of the connector J2 of the CC-PC. It is therefore recommended the connectors of the gluecard have the same orientation as the connectors of the CC-P C since otherwise all signals would need to be Using the CC-PC in a board design page 5

The view is on the top of the modules, i.e. the connectors are below. All measures are in mm 2.4 Connectors The connectors used to plug the CC-PC on the board are MOLEX 240 pin connectors, which exactly match the Digital Logic SmartBus480 connectors. They are sur face mount connectors of mm pitch and 5 mm high and have the following specifications [1]. In case of mounting any component under the CC-PC, its height should not be more than 2 mm; however this is not recommended. 4 (female) connectors are needed per board (see 2.4.2). Connectors will be bought centrally please register your required quantity with either Beat Jost or Niko Neufeld. page 6 Using the CC-PC in a board design

The differential output signals are terminated with 120? resistors. The RJ 45 jack is connected directly to the CC-PC connector J9 as shown below in Figure 9.

Note that the resistors on the differential lines should be as close to the CC-PC connector as possible. 2 The Ethernet Media Access Controller (MAC) is a part of the CC-PC, it is an i82559 from Intel. The two differential RX and TX signals need to be connected to the RJ45 connector on the edge of the board. Ethernet requires a suitable magnetic filtering circuit as close as possible to the connector, which is the reason for using the recommended RJ45 connector with integrated magnetic filtering. The pin connectivity of the PulseJack J0035 RJ 45 connector is listed in T a b l e 4: 2 NOTE: The resistors are extremely important especially when operating with long cables.

The standard CC-PC will not even have support for graphics. The required parts and design gu ide-l i n e s for the connectors for these interfaces can be seen from the reference design. 2.5 Signals to route between CC-PC and gluecard The connection between the Gluecard and the CC-PC has been reduced to the minimum number of signals according their importance. C o n s e q u e n t l y from connector J1 (see also Figure 2 and Figure 6) of the CC-PC ONLY the Power and Ground pins are routed on the PCB as follows: Table 5 Signals of J1 on the CC-PC to be connected to the carrier PCB.

18 2.7 Signals and Addresses with specific use by the Gluecard The gluecard uses a few signals internally: The signals of the printer port of the CC-P C GPIO7 and GPIO8 Chip-Select 0 (CS0), Local Bus Addresses 0x0 to 0x40 These signals should not be used by the electronics of the carrier card. The address decoding on the carrier card should make sure that the there is no clash with the addresses used by the gluecard (respect Chip-Select 0) page 14 Using the CC-PC in a board design

As a guideline of the usage take for example pin B116 (TDO3). This pin has to be connected to the TDO signal of the last IC in the 3 rd JTAG chain. It is considered an Input of the connector I2C The I2C is a simple bi-directional bus consisting of two wires, serial data (SDA) and serial Clock (SCL) that c arry information between the devices connected to the bus. Each device is recognized unique address can work either as a transmitter and/or a receiver, depending on the Function of the device. The device which initiates a data transfer on the bus is considered the bus master, while all other devices connected to the bus are regarded as bus slave. Using the CC-PC in a board design page 17
22 Figure 13 The I2C bus The bus performs serial, 8-bit oriented, bidirectional data transfer, which can be made up to 100 KHz in the standard mode, up to 400 KHz in the fast mode, or 3.4 MHz in the high speed mode. The gluecard supports 100 khz mode only. As the number of devices and the bus length is restricted by the 400 pf capacitance of the I2C bus, a 5-channel I2C hub (PCA9516) is used on board which buffers the data and the clock lines, enabling five buses of the 400 pf as shown in figure. It can also be used to run different buses at 5V or 3.3V JTAG The Gluecard provides three JTAG buses each one using the following five dedicated signals, which must be provided on each chip that supports the standard: T R S T : Is a Test-R e s e t i n put which initializes and disables the test interface. TCK: Is the Test Clock input which controls the timing of the test interface independently from any system clocks. TCK is pulsed by the device controlling the test and not by the tested device. It can be pulsed at any frequency (up to a maximum of some MHz), or at varying rates. T M S : Is the Test Mode Select input which controls the transitions of the test interface state machine. TDI: Is the Test Data Input line, which supplies the data to the JTAG registers (Boundary Scan Register, Instruction Register, or other data registers). TDO: Is the Test Data Output line, which is used to serially output the data from the JTAG registers to the device controlling the test. It carries the sampled values from the boundary scan chain (or other JTAG registers) and propagates them to the next chip in the serial test circuit. The normal organization of the test circuit on a board that incorporates several chips with JTAG support is to connect TRST, TCK, and TMS to e v e r y chip in parallel, and to connect TDO from one chip to TDI of the next in a single loop. This way the board presents a single test interface that has the same five signals discussed above. A simpler arrangement, for boards that have only a few chips with JTAG interfaces, is to provide one JTAG test-port for every such chip, and control the tests independently. page 18 Using the CC-PC in a board design
23 2.8.3 Local bus Local Bus helps PCI- Bus to communicate with non PCI devices. It s a 32 -bit bus 3 that can operate in both multiplexed or non-multiplexed mode, with memory, which can be programmed for 8-, 1 6 -, or 32-bit width. The gluecard only supports the non-multiplexed mode. It can operate at frequencies up to 60 MHz, and is asynchronous to the PCI clock. The PCI 9030 is the local bus master, which can transfer data between the local and internal registers and memories. The bus width depends on the local address space register settings. There are four address spaces and one default space from which space 0 is used internally. Figure 14 Local Bus Block Diagram Local Bus Arbitration The Gluecard only supports Single Master operation, i.e. the gluecard is the ONLY master on the local bus Local Bus Transaction The local bus is capable of performing four types of transaction which are listed as follows: Read W ri t e Read Burst Write Burst The address bus LA [27:2] drives a valid address and continues until the cycle ends. At same time the LAD [31:0] address data bus, derives a valid address onto LAD [27:0] one clock cycle prior to the address strobe assertion (ADS #). The data is then driven onto the LAD [31:0] data bus one clock cycle after the de- assertion of the ADS# and continues until the cycle ends. The READY# signal is then asserted to indicate that there is a valid read data on the bus to accept or a write da t a phase has been completed. Below there is a an example single cycle timing diagram [2]. 3 Note: the address space of the Local Bus is only 28 b i t s, i. e MB. Using the CC-PC in a board design page 19
24 Figure 15 Local Bus Single-Cycle Timing Diagram Local Bus Address Map The gluecard uses a few addresses in the PLX 9030 address space (24 bits) for addressing the I2C and JTAG controllers and the other control registers. The total address space needed is 64 Bytes. This address space is also associated to Chip Select 0 (CS0 #) of the PLX Most of the cards using the CC-PC with the gluecard will also use the LHCb quad Gigabit Ethernet plug-in card. This card has 64 kb of address space (16 bits) starting at 0 and reacts to Chip Select 2 (CS2) of the PLX The PLX 9030 features that the offset of an address window has to be a multiple of its size. To maximize the useful address space on the carrier board the following address mapping is specified Table 7 Local bus address ranges and decoding strategy Address Range S i z e C S 0 # C S 1 # C S 2 # Addressed Carrier Equipment Action 0x x0000 FFFF 64 kb Gluecard Ignore 0x x0001 FFFF 64kB GbEthernet Plug-in Ignore Table 7 demands that the carrier card should ignore all addresses which are blow 128 kb and/or when either CS0 or CS2 are asserted. 4 Note that the Chip selects of the PLX are active -l o w s i g n a l s. page 20 Using the CC-PC in a board design
25 2.8.5 Reset Its required that it must be possible to reset the controls interface of an electronics board without impairing the main function of the board. Resetting in this context means the action to bring the controls interface from any state into a known state. As an example, for a Credit-Card PC resetting means a hardware reboot by pulling the hardware reset line, similar to pushing the reset button on a desktop PC. The way to reset the ECS interface is to use the VME reset signal (SysReset# in VME terms 5 ), a 3.3Volt active-low signal which is part of the standard VME crates. For standard VME crates there is also a provision in the control interface of the VME crate to remotely activate this line through the fan-tray of the crate. This is true for the Cern standard 6U VME crates and also for the Cern standard 9U crates. Of course also a reset -button or similar can be used to activate the reset line. This is optional, whereas the connection to the VME reset line (or alike for the backplane in use) for remote reset is mandatory. Figure 16 shows schematically the connection of the VME Reset signal to the CC-PC and the Gluecard.

In cases where a special backplane is used the position of this signal can change. The signal is, for Cern standard crates, driven by the crate fan tray. Using the CC-PC in a board design page 21
26 3 Power Requirements 3.1 Credit-Card PC The credit -card PC needs only +5 Volts as supply voltage. At this voltage it draws approx. 1 A, hence a power consumption of ~5 W. 3.2 Gluecard The power and voltage requirements of the gluecard are as follows 1 W at 3.3 Volts 200 mw at 5 Volts No other voltages are needed. page 22 Power Requirements

In this appendix we show a few specific implementation issues used in the design of the Tell1 board. B.1 Local Bus Termination All Local Bus lines should be terminated with an RC network to ground as shown in Figure 17 LHCb Connector Local Bus Line Bus End 47W 47W 22 pf 22 pf Figure 17 RC Termination network of the local bus lines. The RC network should be located as close as possible to the extremities of the bus. B.2 Local Bus Address Map Table 9 shows the address map of the local bus as implemented on the Tell1 board. Table 9 Local bus address ranges and decoding strategy Address Range S i z e C S 0 # C S 1 # C S 2 # Addressed Carrier Equipment Action 0x x0000 FFFF 64 kb Gluecard Ignore 0x x0001 FFFF 64kB GbEthernet Plug-in Ignore 0x x0FFF FFFF 128 kb to 256 MB Carrier Card Access Chip Select CS1 is associated with the maximum address space of the PLX Local Bus (256 MB).
