  16. FUNCTIONALITIES [VME Interface] • VME Interface • D32/A32 access mode (AM 0x09) • 8 bits of board address (A31-A24) (2 rotary switches). • Geographical addresses usable if the manual address is 0x00 (reloaded at power up or by sysreset) • Interrupts are possible, but have to remain optional. They may not be handled by every types of VME controllers. TTC meeting, 2nd of May 2006

  17. FUNCTIONALITIES [Signal Adjustments] • Adjustable parameters (via VME registers) • BC1, BC2, BCref • Adjustable level on the comparator input • Multiplexing between each input and the internal 40.078MHz clock • Adjustable phase shift (steps of 0.5ns) • Main BC • Multiplexing between BC1, BC2, BCref and internal clock • Adjustable phase shift (steps of 0.5ns) • Orbit1 and Orbit2 • Adjustable level on the comparator input to match various types of signals • Adjustable phase shift before the latching with the corresponding BC • Multiplexing between each input and an internal counter • Adjustable length • Adjustable coarse delay (steps of 25ns) • Adjustable phase shift (steps of 0.5ns) before the output • Main Orbit • Multiplexing between the two orbit sources and an internal counter • Adjustable length • Adjustable coarse delay (steps of 25ns) • Adjustable phase shift (steps of 0.5ns) before the output TTC meeting, 2nd of May 2006

  18. FUNCTIONALITIES [Status & Remote Control] • Board status data • Read only registers: Orbit available, QPLL lock, TTC ready, machine mode • Leds: selected signals, QPLL lock, available orbit, VME access, VME berr, BST signal ready... • Remote control of the adjustments • Orbit comparator level/ orbit dephasing: FIFO containing the 128 last BC counts between two consecutive Orbit signals (ideally 3564 each). The content of this FIFO can indicate a bad level on the comparator, a dephasing, a wrong synchronisation. This FIFO is filled at reception of a VME command. • Clock status: QPLL status indicates if the clock is absent or if the comparator level is wrong. Would some other ways being required? • Orbit counter, 32 bits (106 hours). Could be reset, either manually, or at the beginning of a run if required TTC meeting, 2nd of May 2006

  19. FUNCTIONALITIES [Working modes] Beam Dump Beam Dump E(450GeV -> 7TeV) E(450GeV -> 7TeV) time injection ~15 min ramping ~28 min squeeze ~15 min physics ~10-20 H • Manual and automatic modes for signal selection • Manual mode: the source of each output signal is manually selected • Automatic mode: • Change the selected sources according to the machine mode • 2 types of parameters must be configured: • Which machine mode is considered to be ‘run’ (ex: ramping, adjust, collide..) or ‘no run’ (beam dump, no beam, …) • Which source for each signal must be selected during ‘run’ or ‘no run’. Example for the Main BC: Internal clock during ‘no run’ periods, and BCref during run periods • 3 different configurations can be defined for the signal selection. • Which means: • 1 register to define in which mode we are (manual, auto1, auto2, auto3) • 1 register to define which machine mode corresponds to which state • 1 register to define the sources set when ‘no run’………………… • 3 registers to define the sources set when ‘run’ (1 per auto mode)… Run/no run Automode1 Automode2 Automode3 TTC meeting, 2nd of May 2006
