Prototyping Microsemi Rad Tolerant Devices / FPGA / PROTO

Aldec and Microsemi have joined forces to offer an innovative, reprogrammable prototyping solution for Microsemi RTAX-S/SL, RTAX-DSP and RTSX-SU space-fight system designs. Unlike the traditional One Time Programmable (OTP) anti-fuse space-qualified FPGAs, the Aldec prototype adaptor uses flash-based, Microsemi ProASIC 3E FPGA technology for design prototype re-programmability.

The RTAX-S/SL and RTSX-SU prototyping solution from Aldec allows designs that use these Microsemi devices to be prototyped with a reprogrammable FPGA device. This not only speeds up the development process but also mitigates risk by using a proven development methodology. Alternative methodologies that use reprogrammable devices during initial design development can be both costly and unreliable, due to the additional components required to support the development FPGA. The Aldec solution with its pin-for-pin compatible adaptor avoids such issues.


The software conversion tool automatically converts the RTAX-S/SL and RTSX-SU EDIF netlist into a ProASIC3E EDIF netlist, eliminating the requirement to perform manual mapping of RTAX and RTSX primitives and memory blocks to ProASIC3E devices. Aldec’s prototyping adaptor boards and netlist converter reduces overall project costs and shortens design validation time of the RTAX-S/SL and RTSX-SU project.


The pin remapping utility allows automatic Physical Design Constraint (PDC) file conversion, which eliminates the need for additional manual work.


The Aldec RTAX development solution has been successfully used in numerous flight proven designs.


The RTAX/RTSX prototyping adapter provides a fast, efficient and effective way of targeting a variety of Microsemi’s high reliability, radiation tolerant, antifuse FPGAs and flash-based ProASIC3 devices.
