Specific action list following TDC review meeting on 16 March
Summary of Gianluca and Lukas comments

Action list Gianluca Action list Gianluca
Checking of DLL, hit register and Encoder designs to confirm selection of the right edge Consideration of possible revision of encoding logic to keep encoding functional also in case of code with spurious 0 at the last location Coarse time stamp unit Verification of RTL design Synthesis Verification post synthesis P&R Verification plan and test bench for the full TDC Revision of full TDC once complete Allocation of powering stripes for the DLL and fine registers section

Action list Lukas Action list Lukas
Plot and table of propagation delay vs voltage for all conditions and corners Remove the bias driving circuit for the edge detector because not needed Correct documentation for the DE_Vampl parameter. Correct values already distributed by Current mirrors using transistors with different vt Lukas made all checks including process and mismatch MC. To discuss with Paulo in a dedicated one to one Voltage follower for the charge pump to be verified for SSF and FFF corners Was designed for higher voltage Comment on 30% of bias current from min bias circuit To be discussed with Paulo Adding of low pass RC on min bias DLL simulation in closed loop Consider triplication of transistors on reset line SEU on reset issue

Action list Alex Action list Alex
Independent reset for each DLL for startup and reset Independent low power mode for each DLL Triplication of registers controlling DLL reset lines
5
Action list for the team
Decision between designs with 40 or 20 DLLs
