10. 20 Feb. 2001LVL1 muon trigger simulation meeting10 Current Status -1 Prototype Code was finished on Mar ’ 00 Simulate  R,  in a High Pt Board for muon tracks These are very preliminary results and we found some bugs exist  R,  in a High Pt Board for muon tracks

11. 20 Feb. 2001LVL1 muon trigger simulation meeting11 Current Status -2 Comparison of simulation results with Yoji ’ s results starts But, there are some problems Geometry in DICE is different from the final one We have changed TGC numbering scheme (sector No, chamber No etc.) for production/electronics/simulation from one used in DICE.

12. 20 Feb. 2001LVL1 muon trigger simulation meeting12 Migration on ATHENA/PESA scheme Trigger Simulation is a “ algorithm ” in ATHENA framework Framework Change 1. Use TDS (Transient Data Storage) for Digitizer input (DICE Hit output equivalent) Digitizer output (RAW data equivalent) Trigger output (MUCTPI input equivalent) Test Vectors 2. Create/Use Detector Data Service For both trigger and detector simulation Geometry Connection Table
