1. GR740 Reference Design Thomas Badinand Marketing & Sales Manager
RUAG Space AB
ESA GR740 day –

2. Reference design and basic software for a single board computer based on GR740
The project is a technology development activity funded by ESA
RUAG is responsible for design and manufacturing of the reference design board, test equipment and validation.
Cobham Gaisler is the responsible for design of the FPGA and Software design
RUAG and Gaisler, with input from “external reference customers”, share the responsibility to finalize the requirements of the reference design board
The purpose of the board is to provide a possibility for early design for coming flight projects

3. Why RUAG Space with Gaisler?
RUAG Space has extensive experience in developing electronics digital computers for space
Experience of GR740
One of RUAG Space latest product is a Single Board Computer in VPX format
Companies are close geographically (Gothenburg region)

4. Main objectives
To create a reference design, available to all European space users, a single board computer using the GR740
Reference design data package
Development of Elegant Breadboard
Verified at functional and performance level (TRL 4)
Supported by a Qualification Test Plan
Accompanied by Boot software and Board Support Package & Device drivers
To create a reference design, available to all European space users, a single board computer using the GR740 system-on-chip device. The reference design shall:
Reduce risk associated to new development inside a specific programme
Create a seed to create a European offering for off-the-shelf space computers at higher TRL
Include peripheral components required to operate the GR740 memories, interface drivers, clock generators, glue logic FPGA etc) with preference given to European components while not excluding non-European components if more adequate.
Be available as a GR740SBC reference design data package providing design collateral without limitations and restrictions on distribution of the information.
Be verified at functional and performance level on a EM/EBB (TRL 4)
Be supported by a Qualification Test Plan that has been established in view of a future space qualification
Be accompanied by several software products; Basic software consisting of Boot software and Board Support Package & Device drivers, and a test application also including EGSE Test Software.

6. Involvement of the reference customers
Airbus Defence and Space
OHB System
Thales Alenia Space
Contribution:
Input to the requirements and the architecture of the GR740 SBC
General features, form factors and hardware and software aspects
Support to the overall plans focusing on interfaces and risk assessments, and participation in the SRR.

7. Block diagram of Reference Design
The Proposed design is illustrated in the figure.
Basis for the hardware reference design and the EBB.
The final block diagram for the EBB will be elaborated in the activity
Trade-offs expected between for example the amount external interfaces, board form factor and backplane adaptations.
Blocks with dashed border: foreseen extensions to the reference design, not fully covered in baseline reference design.
The figure does not indicate assignment to e.g. front or rear panels.

8. Basic Software Based on GRBOOT from Cobham Gaisler
Board Support Package (BSP) will adapted to the new SBC design.
A standby monitor will be developed supporting PUS services over SpaceWire by reusing the standby monitor developed in previous activities
│RUAG Space│

9. Prerequisites for the design
Compatible with backplane standard
Candidates such as SpaceVPX (VITA 78.0) or Serial cPCI for Space
Not larger than 6U
GR740
Backplane expected to support High Speed Serial Link (HSSL)
FPGA for I/O interface flexibility
Adapted to expected market needs
Detailed design and interface allocation to be defined
EBB form factor possibly 3U?
│RUAG Space│

10. EBB Descoped variant of the Reference Design
Possibly reduced amount of backplane interfaces
Possibly reduced amount of external (front) I/O interfaces
Unchanged processing performance
Potential extensions compared to the Reference Design (e.g. HSSL)
Form factor 3U or 6U
To be developed, manufactured and validated in the activity

11. Schedule Kick off reached mid October 2019
Initial user need collection phase ongoing
SRR planned for February 2020
PDR planned for Q2 2020
Detailed design and CDR to be finalised Q4 2020
Product validated and available for use Q4 2021
