Design policy

Detailed trigger simulation based on real electronics design Can describe logic according to real

implementation of ASIC Can describe individual module Can describe connection between modules Can treat multi-bunch simulation

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

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.

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
