Mai 31th 2011 Christophe Beigbeder PID meeting5 Under design: a 16-channel WaveCatcher Based on the very encouraging results of the 16-channel crate, we started the design of a 16-channel WaveCatcher board This board will be compatible with both SAM (256 cells/ch) and SAMLONG (1024 cells/ch) –The board can be synchronized externally => possibility to scale the system up to 320 channels in a crate The first prototype will be available in September 2011 SAMLONG Chip 1024 pts GS/s 2 Channels Dual 12 bits ADC SAMLONG Chip 1024 pts GS/s 2 Channels Dual 12 bits ADC 4 Analog Input Trigger In/out SAMLONG Chip 1024 pts GS/s 2 Channels Dual 12 bits ADC SAMLONG Chip 1024 pts GS/s 2 Channels Dual 12 bits ADC FPGA 4 Analog Input Trigger In/out FPGA  VME Format  USB 480 Mbits/s  Optical fiber output

Mai 31th 2011 Christophe Beigbeder PID meeting6 Board features (not exhaustive)  Possibility to add a individual DC offset on each signal  Possibility to chain channels by groups of 2  2 individual trigger thresholds on each channel  External and internal trigger + numerous modes of triggering on coïncidence (11 possibilities including two pulses on the same channel => useful for afterpulse studies  Embedded digital CFD for time measurement  Embedded signal amplitude extraction  Embedded charge mode (integration starts on threshold or at a fixed location) => high rates (~ 3.5 kEvents/s)  2 extra memory channels for digital signals  One pulse generator on each input  External clock input for multi-board applications  Embedded USB and Ethernet interfaces

Mai 31th 2011 Christophe Beigbeder PID meeting8 SCATS : functional synopsis

Mai 31th 2011 Christophe Beigbeder PID meeting9 Layout synopsis Layout done. Simulation post layout done for the Ram. To be done for the 2 channel block. Layout on going Simulation post layout will follow Layout on going Post synthesis problems to be fixed Simulation post layout will follow

Mai 31th 2011 Christophe Beigbeder PID meeting10 The layout of Scats ( digital part ) gives precious information for post layout simulations and for detecting timing problems and underwent a complete fault coverage. We need to simulate RAM with specs extracted from the layout simulation Write pulse min width: 500 ps Read pulse min width : 1ns Rd to output : ~ 3 ns Set up and Hold time : ~ 200 ps These parameters are integrated in Verilog ram simulation model. Post layout simulation possible with a very performant simulation test bench SCATS : Digital part Scats_digital layout 948µm x 933 µm
