5 1 Introduction The actual trigger functions of the Level 1 Muon Trigger (L1MU) system are performed by the Muon Trigger Cards (MTCxx s) and their associated Muon Trigger Flavor Boards (MTFB s). The L1MU system is divided into eight octants for each of the three geographical regions (CF, EFN, and EFS). Further, there are two MTCxx cards for each octant. Generally, one MTCxx card makes use of L1 Central Fiber Tracking Trigger (L1CFT) tracks and scintillator counter hits (called 05 logic) while the other MTCxx card makes use of wire chamber hits (CF) or mini-drift tubes (EF) and scintillator counter hits (called 10 logic). The L1MU system is described further in Refs. [1] and [2]. To maximize flexibility and to minimize the engineering effort, the MTCxx card is uniform throughout the L1MU system. Different logic inputs, outputs, and algorithms are accommodated by the use of a MTFB, which connects to a MTCxx. Thus, the MTFB changes the flavor of each MTCxx. Distinct MTFB s are needed for different regions (e.g. CF versus EFN), different trigger algorithms (e.g. 05 versus 10 ), and perhaps even different octants (e.g. top and sides versus bottom octants). Figure 1 shows the overall design of the MTCxx and MTFB. See Ref. [3] for a full description of the MTCxx card. This document describes the design and logic of each flavor of the MTFB. Figure 1 - MTCxx Card and Flavor Board Outline 5

6 2 General Description The MTFBs reside on the MTCxx cards, which are 9u x 400-mm VME cards with 16 available serial inputs (and receiver cards) along with a complete VME interface. While the MTCxx cards will all be identical, the serial inputs to these boards will differ depending on which flavor board the MTCxx is housing. For instance, the CF MTC05 cards only require 13 serial inputs of which 10 are from the CFT, 2 from the APHI counters, and one for the CMSC C hits. A complete list of the serial inputs for each flavor card is given in Appendix A. While not all flavors of the MTFB use all the possible inputs and outputs to the MTCxx, the total number of I/O pins on the MTFB is determined by the maximum number of I/O pins needed by any flavor of MTFB (since the I/O specifications are the same for all MTFBs). Below is a description of the total number of I/O pins requires to satisfy any flavor of MTFB: Serial Inputs = 16 x 16 = 256 lines 53 MHz RF Clock Start FLEX Chip Download = 13 lines Power GND Additional Timing Signals (i.e. BC, DAV) Output Trigger Decision = 36 lines Output Supplemental Data = 16 lines Test Points = 29 lines With up to 16 serial inputs required per MTCxx, many pins are needed to connect the MTCxx and the MTFB. One connector that fills our requirements is the SAMTEC MOLC/FOLC family of connectors. These are 4 row, x micro strip connectors which have up to 50 rows (for a total of 200 pins). In addition, the mating height for these connectors is from PCB-to-PCB (for SMD). The connectors also have a current rating of 1A per pin. (The MOLC connectors go on the MTFB while the FOLC are on the MTCxx cards.) In addition, we have added P6 to transfer the test point data. P6 is from the SAMTEC TFM/SFM family of connectors which has two rows of pins. Appendix B shows the complete pin outs for the MTCxx to MTFB connection. See also Reference [3]. To facilitate the large number of pins, we are using six SAMTEC connectors. Table 1 shows the characteristics of each of these connectors. CONNECTOR LABEL ROWS PINS/ROW TOTAL # PINS P/N P MOLC S-Q-LC P MOLC S-Q-LC P MOLC S-Q-LC P MOLC S-Q-LC P MOLC S-Q-LC P TFM S-D-LC Table 1 - The six connectors used between the MTFB and the MTCxx This gives a total of 580 pins. P1 P4 are used for the deserialized data. Each P1 P4 connector carries four serial cables worth of data. P5 is used for timing, trigger decisions, FPGA downloading, and other I/O functions. P6 is used to transfer the test point signals from the MTFB to the MTCxx and then to the front panel connector (p/n 3M 3433). 6

7 To determine the maximum area needed to facilitate the FPGAs, passive devices, and connectors used on the MTFB (all flavors of the MTFB have the same dimensions), the size and number of each type of FPGA needs to be determined. Table 2 gives preliminary estimates for the number of each type of FPGA used on each flavor of the MTFB. MTFB Name Altera FPGA Part # Quantity CF MTC05 Same as EF MTC05 7 Total CF MTC10 10K50VRC K30ATC EF MTC05 10K30AQC K30AQC K100ARC K10AQC EF MTC10 Same as CF MTC10 7 Total Table 2 Summary of MTFB FPGA Requirements From Table 2, we see that the total number of FPGAs needed on each flavor of MTFB is the same. In addition, the total space requirements of the FPGAs are approximately the same for each flavor. Given this, an estimate of the dimensions of the MTFB can be made. Table 3 gives the dimensions and package types of the proposed FPGAs. Altera Device # Package Name Description Dimensions(WxLxD)(in) 10K50V/100ARC240 QFP Power Quad Flat Pack x x K30ATC144 TQFP Thin Plastic Quad Flat Pack x x K10AQC208 QFP Power Quad Flat Pack x x Table 3 - Package Type and Dimensions for Proposed FPGAs Figure 2 shows an example layout of the CF MTC10 MTFB, while Figure 3 shows how the MTFB would sit on the MTCxx card. Both of these figures are drawn to scale, where the dimensions of the MTFB are 12 x 6. The connectors in Figures 2 and 3 are located on the underside of the board. Finally, we see that because of the relatively small size of the MTFB, any delays on signals between FPGAs should be small. (If we assume 2 ns/foot, then a 3 inch trace between FPGAs results in a delay of 500 ps.) The loading of the FPGA s on the MTFBs will be done in the same way as the FPGAs are loaded on the Muon Trigger Crate Manager (MTCM). This involves using flash memory on the MTCxx cards to store the FPGA programs and then use the passive serial download (see Ref.[3]). This method uses four (4) control lines that are chained amongst all the FPGAs, and one unique enable line for each FPGA on the board. Using the information from Table 2 and the size of each FPGA program 1, the total memory needed to store the FPGA programs is 0.5Mb for the CFMTC10 and 0.61Mb for the EFMTC05. The total memory dedicated to the FPGA download on the MTCxx card is 1Mb. 1 See 7

Note that there are two (2) 40-pin TFM connectors draw on the MTCxx. The extra connector (P7) is used only by the MTM board. 9

10 3 MTC05 Some introduction here explaining what the inputs are to the MTC05 cards (ef = pix + cft, cf=scint+cft). 3.1 CFMTC EFMTC05 10

11 4 MTC10 Some general comments in here on the inputs to the mtc10 (cf = scint + pdt, ef = pixel + mdt). 4.1 CFMTC Inputs/Outputs The specific inputs and outputs of the CF MTC10 Flavor board and each of the FPGAs are shown in Figure 4 and listed in Appendix B. Also included in Appendix B are descriptions of the input and output of each of the FPGAs shown in Figure 4. Figure 4 - Overview of the CF MTC10 MTFB FPGA Logic The inputs to the CF MTC10 MTFB are broken down into the following components: PDTA = 16x3 = 48 lines PDTB = 16x5 = 80 lines PDTC = 16x5 = 80 lines CMSCA = 16x2 = 32 lines CMSCC = 16 lines CLOCK START 11

12 FLEX Chip Download = 11 lines. The total number of output lines from the CF MTC10 MTFB is 24 and is broken down into the following components: Six 2-bit Counters = 6x2 = 12 lines ACENT(Supplemental Data) = 12 lines JTAG BST Connection The total number of interconnects between the FPGA s on the CF MTC10 MTFB is rather large (>500). In order to test the connectivity between these pins, the JTAG IEEE boundary-scan architecture is incorporated for each of the FPGA s. The boundary-scan test (BST) uses four signals brought in through the external connector J1. J1 is a 10-pin (2 x 5) female plug (i.e. standard JTAG connector). More details will be provided in future revisions as the software for developing this testing is brought online FPGA Design We are using Altera field programmable gate arrays (FPGAs) to form the trigger decisions. From Figure 4, we see that the CF MTC10 MTFB utilizes 7 FPGAs. The function of each of these FPGAs is described below. The complete listing of all the inputs and outputs to each FPGA is given in Appendix C. A CENT - Receives A-layer PDT hits and APHI counter hits and calculates A-layer centroids with APHI confirmation. B CENT - Receives B-layer PDT hits and APHI counter hits and calculates B-layer centroids with APHI confirmation. C CENT - Receives C-layer PDT hits and CMSC C (Cosmic Cap) hits and calculates C-layer centroids with CMSC C confirmation. TRIG1 - Finds A, AB.or.AC, and AB.or.AC.or.BC triggers using centroid information that correspond to the A-centroid range [1,48]. Also or s A-centroids by 12 to give 4 bits of A-cent. The triggers are all 2-bit counters. TRIG2 - Finds A, AB.or.AC, and AB.or.AC.or.BC triggers using centroid information that correspond to the A-centroid range [49,96]. Also or s A-centroids by 12 to give 4 bits of A-cent. The triggers are all 2-bit counters. TRIG3 - Finds A, AB.or.AC, and AB.or.AC.or.BC triggers using centroid information that correspond to the A-centroid range [97,144]. Also or s A-centroids by 12 to give 4 bits of A-cent. The triggers are all 2-bit counters. OCTANT SUM - Receives input from TRIG1, TRIG2, and TRIG3 and calculates the final 2-bit counters for the A, AB.or.AC, and AB.or.AC.or.BC triggers. Also forms final 12-bit counter for A- centroids FPGA Timing/Fitting Given the current trigger logic and CF MTC10 FPGA design, we have calculated the timing and available logic cells (LC s) for each of the FPGAs. The overall L1 muon trigger design specifies that the CF MTC10 has at most 7 ticks (1 tick = 132 ns) to form its trigger decision. Using the simulator supplied with the MAX-plus II (V9.01) Altera package, we can calculate the time required for each FPGA to form a 12

13 decision. We find that the centroid finding FPGAs (A CENT, B CENT, and C CENT) only require 2 ticks (264 ns) to form their centroids. The trigger finding FPGAs (TRIG1, TRIG2, and TRIG3) also require 3 ticks (396 ns) to form the trigger decisions. Finally, the summing FPGA (OCTANT SUM) requires 1 tick (132 ns) to form the final trigger decision that is passed to the MTC Mother board. This gives a total time of only 6 ticks, or 792 ns, to form the CF MCT10 trigger. As a side note, the multiplexers and demultiplexers take up a large fraction of the time spent in the FPGAs. The actual centroid finding and trigger finding routines tend to be very fast ( 40 ns). Included at the end of this document are sample timing diagrams of each FPGA along with the top level design sheet. Because the centroid finding and trigger forming routines are quite large, we have to use larger FPGAs. Table 2 summarizes which Altera FPGAs are used and what percentage of their logic cells (LC s) are occupied. We see that none of the FPGAs use more than 64% of available logic cells. All FPGAs were optimized for speed (optimization value = 10).

The centroid and trigger finding FPGAs have an available 189 user I/O pins while the summing FPGA has an available 68 user I/O pins. In all cases we still have many unused I/O pins. Because of this fact, along with the relative amount of free LC s available on each FPGA, we feel that we have good flexibility in any possible changes that may occur to the logic without having to make changes to the flavor board Power Requirements We can estimate the current requirements of each of the FPGA s used on the CF MTC10 MTFB (operating at +3.3V). Using the formula from Ref. [4], where P = P INT + P IO = (I STANDBY + I ACTIVE ) x V CC + P IO, P IO = I/O power (not determined yet depends on load characteristics), I STANDBY = 10 ma, and I ACTIVE = K * freq * N * tog LC. Here, K is a constant depending on the device (K=45 (10K50V), K=32(10K30A)), freq is the maximum frequency used in MHz, N is the total number of logic cells used, and tog LC is the fraction of logic cells that change level during each clock cycle. This is typically 12.5% according to [4]. Using this formula, we derive the estimates for power consumption for each of the FPGA s used on the CF MTC10 MTFB shown in Table 4. 13

14 FPGA Name Altera Part # Power, P(mW) A CENT 10K50VRC B CENT 10K50VRC C CENT 10K50VRC TRIG1 10K50VRC TRIG2 10K50VRC TRIG3 10K50VRC OCTANT SUM 10K30ATC Table 5 - CF MTC10 FPGA Power Consumption Estimates This gives us a total power consumption of approximately 9.2W for the CF MTC10 MTFB Super Project CF MTC10 The MAX+PLUS II application allows for the simulation of multiple projects. That is, we are able to simulate all seven of the FPGA s in one project. Thus, the timing for the entire CF MTC10 MTFB can be simulated. The multiple project simulation combines the timing from each of the individual FPGA s into an overall timing for the MTFB, where the delay time for signals that migrate between FPGA s is zero. This should not be a problem as we anticipate the delay time to be on the order of a few hundred ps. Figure 20 shows the timing for the entire CF MTC10 MTFB for a given set of inputs. More test vectors are needed to fully test the timing. Figure 20 shows that the final output from the CF MTC10 MTFB arrives in 6 ticks (6 x 132 ns). The top-level design of the CF MTC10 MTFB is shown in Figure 19. This figure also shows the paths of all the signals in-between each FPGA LED s The LED s used to monitor the MTFB functions are mounted on the MTCxx front panel. A description of these LEDs can be found in the MTCxx functional description note FPGA Testing To produce the timing diagrams of each of the FPGAs shown at the end of this document, test vectors were created to simulate the inputs to the FPGAs. The test vectors are comprised of all possible combinations of TRUE logic found in the logic AND/OR network of each FPGA. For each 132ns bunch, one logic element was tested to see if it produced a TRUE output at the correct time. Note that only one TRUE logic element was tested at a time. Given that all the TRUE logic elements were tested, any combination of these elements that may occur within the same 132ns bunch crossing, should give the desired result. 4.2 EFMTC10 14
