Description
In the context of the CMS Phase-2 tracker back-end processing
system, two mezzanines based on the Zynq Ultrascale+ Multi-Processor
System-on-Chip (MPSoC) device have been developed to serve as
centralized slow control and board management solution for the
Serenity-family ATCA blades.
In this talk, we present the current revision of both Serenity
baseboards and the developments on the MPSoC mezzanines to execute
the Intelligent Platform Management Controller (IPMC) software in
the real-time capable processors of the MPSoC. In coordination with
the Shelf Manager, once full-power is enabled, a CentOS-based Linux
distribution is executed in the application processors of the MPSoC
to run the slow-control software.
Summary
In the context of the CMS Phase-2 tracker back-end processing
system, two mezzanines based on the Zynq Ultrascale+ Multi-Processor
System-on-Chip (MPSoC) device have been developed to serve as
centralized slow control and board management solution for the
Serenity-family ATCA blades.
The Serenity family consists of two ATCA-sized boards designed to
explore alternative configurations. Serenity-A is designed around a
single Virtex US+ FPGA with up to 128 high-speed transceivers, each
with a line rate of up to 25 Gb/s. 120 high-speed lanes are
connected to Samtec Firefly optical transceivers; four are used for
the DAQ path, one is used for the CMS timing and clock distribution
(TCDS), and the remaining links for slow-control and management
tasks provided by the MPSoC mezzanine in the "FMC+" format.
Serenity-Z contains two sites that utilize Samtec z-ray interposer
technology mounting removable FPGA-based daughter cards. Each site
is connected to 18 Samtec Firefly optical transceiver sites. All of
them can take the form of x4 or x12 (16 Gb/s or 25 Gb/s) depending
on the daughter card used. The choice of slow-control and board
management is as well flexible between the combination of a
com-express (CMX) Computer-on-Module (CoM), a DIMM-based IPMC, or an
integrated MPSoC mezzanine in the "CMX-Extended" format.
In this talk, we present the current revision of both Serenity
baseboards and the developments on the MPSoC mezzanines to execute
the Intelligent Platform Management Controller (IPMC) software in
the real-time capable processors of the MPSoC. In coordination with
the Shelf Manager, once full-power is enabled, a CentOS-based Linux
distribution is executed in the application processors of the MPSoC
to run the slow-control software.
