Christophe Beigbeder PID meeting Young researcher project submitted by Nicolas on PID project. - > Still waiting news from ANR ! Caen Physics Lab has “ officially “ joined the collaboration for their participation in the SCATS TDC. The 2 engineers could be called “ associate members “. Christophe Beigbeder PID meeting Mai 31th 2011
Christophe Beigbeder PID meeting Setup @ Orsay Mezzanine : -8 channels CFD like + Amp for charge measurement : the design is ongoing with a new collaborator @ LPNHE We are building the PM setup thanks to the expertise of Veronique ‘s team. We plan to test the performance of the mezzanine with a wave catcher board and its software : time ( discriminator ) and charge are acquired to measure the walk Mother board : ADC + SCATS + FPGA - Associate time & charge - Data packing. - Bus interface : USB, GVbus -> equips both PM test setup @ Orsay and CRT Christophe Beigbeder PID meeting Mai 31th 2011
SCATS : functional synopsis Christophe Beigbeder PID meeting Mai 31th 2011
Christophe Beigbeder PID meeting 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 Christophe Beigbeder PID meeting Mai 31th 2011
Christophe Beigbeder PID meeting SCATS : Digital part 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 layout 948µm x 933 µm Christophe Beigbeder PID meeting Mai 31th 2011

Christophe Beigbeder PID meeting Each of the following blocks must not exceed a height of 50µm to match topological design constraints Asic_fifo_control block of Scats : 591µm x 50µm Pcsm block of Scats :131µm x 50µm Christophe Beigbeder PID meeting Mai 31th 2011
Two channels block layout 32-bit wide * 8-word long FIFO Fine Time measurement: DLL 440µm 3300µm Christophe Beigbeder PID meeting Mai 31th 2011
Christophe Beigbeder PID meeting Electronics is split in two parts : one directly mounted on the PM base receiving the PM signal and processing it with TDC/ADC the other one concentrates and pack all the channels to send data to the DAQ Electronics on the detector : Mechanical constraints ->FBLOCK design Thermal constraints -> 200 w per crate to be confirmed Power distribution issues . ->Could use rad hard power supply like LHCb Cables and links Only one link per sector Christophe Beigbeder PID meeting Mai 31th 2011
Christophe Beigbeder PID meeting FBLOCK PCB FE boards plugged into “crate slots” PCBs and backplane(s) partitioned in columns could be removed “completely” Christophe Beigbeder PID meeting Mai 31th 2011
Christophe Beigbeder PID meeting Conclusion Setup for PM tests is on tracks We started the design of the mezzanine board Version with commercial components (CFD like) . Architecture has to be study depending on : Mechanical constraints Backplane, cooling and power issues SCATS : layout of the 16 channel , simulation post synthesis and post layout are ongoing Submission still foreseen for July And happy birthday to Daniel !
