Description

The CMS L1 Trigger processes the muon and calorimeter detector data using a complex system of custom hardware processors. A bit-level emulation of the trigger data processing has been developed. This is used to validate and monitor the trigger hardware, to simulate the trigger response in monte-carlo data, and for some components, to seed higher-level triggers. The multiple-use cases are managed using a modular design, implemented within the modular CMS offline software framework. The requirements, design and performance of the emulators are described, as well as the iterative process required to bring the emulators and hardware into agreement.
