T608-36QC
SRAM based FPGA for space applications
Contrary to antifuse type Field Programmable Gate Arrays (FPGA), SRAM based types offer the possibility of in-system
reconfiguration. Radiation hardened FPGA types using SRAM based configuration programming are currently being
introduced /developed for space applications by the European manufacturer Atmel. While the prospects of exploiting this
additional flexibility potential for re-configurable payload systems are seriously being considered there is still very limited
experience with the safe utilisation of these features. This activity shall determine (1) if current Product Assurance
requirements and practices for on board SW reconfiguration are applicable and sufficient for FPGA configuration data or if
modified/additional provisions are required and (2) which methods and requirements are applicable to establish conformance
of specific and dynamic FPGA reconfigurations with fixed system constraints during the application development process.
The effectiveness of the proposed method(s) and requirements shall be suitably demonstrated.

Study of long term parametric drifts of EEE components for inclusion in component
Title:
detail specifications and worst case analysis
Worst case analysis is a typical requirement of the ESA projects and is based on the known drift of EEE components during
the mission life. These drifts are important as they help establish the system performance parameters with in the given
mission profile. However, the attempted to re-validate the current drift values cited in the ESA PPS 01 301 and include these
in the Worst case analysis standard envisaged that the values listed are based on a series of assumptions and activation
energies that may not be applicable today. Additionally, as an outcome of an ECSS working group on how to approach the
calculation of the Worst Case limits, it emerged that, inspite of ESA listing some drift paremeters in their specifications,
industry wished to use other figures and for some technologies(drift parameters are technology, process and in some cases
even manufcaturing line dependent) there was no easily obtainable referenece data. With the present activity it is now
proposed to launch a study that determines what data resides with space/aerospace/automotive/commercial procurement
agent, user and manufacturer. This study will then take existsing available data and provide clear dirt formulae for use in an
ECSS standard. In addition where data does not exist it will define the missing program of work.
Deliverables:
Technical note (incl. reviewed - consistent - data to submit to ECSS for approval and inclusion in the ESCC abd ECSS
documents). Work plan for missing data retrieval.
