Description
ARIETIS is a standalone 3 axes electronic gyroscope which is currently under development by INNALABS (Ireland) and EREMS (France).
One of EREMS responsibility on this product is the development of the FPGA design, based on NanoXplore European technology, the NX1H35AS (NG-Medium).
The ambitious measurement precision of this gyroscope is at the root of several technical challenges for the FPGA engineers:
- Complex regulation loops
- Large amount of resource used (about 60% of NG-Medium)
- Very high working frequency (80MHz target)
- New FPGA technology and developing tools
The project started with the implementation of the design in an 'easy' FPGA target on first models : the igloo2 manufactured by Microchip.
This helped the teams validate the algorithm and functional part of the design, without being slowed by any potential problem coming from development tools.
Year 2022 however has been a big turning point for Arietis as the first timing closure campaign on NG-medium target has been completed with very satisfying results.
We invested a lot of effort on NanoXplore's nxmap development tool, trying different options, defining tons of timing and placement constraints, and also tweaking our design for better implementations.
This presentation aims at sharing part of EREMS's work and results with the Space FPGA community, as we consider ARIETIS as a good example of what can already be achieved with NanoXplore Technology.
