L1 Trigger Offline Software

Goal of this page

This chapter documents the L1 trigger offline software. The hardware is documented in the Trigger TDR and via some subsystem wiki pages at L1Trigger.

This page, as well as the linked pages, are under active restructuring.

Introduction

The L1 Trigger offline software includes packages that provide:

• data formats for all the L1 EDM products
• bit-level emulation of the trigger electronics
• tools for interpreting, monitoring, analysing and validating L1 data.
