gners have asked for a quick, straightforward way to prototype radiation-tolerant designs in Actel's antifuse-based RTAX-S FPGAs, stated Dr. Stanley Hyduke, president of Aldec, Inc. Aldec responded with a complete and reliable solution based on Actel's ProASIC3 flash-based FPGAs
that will simplify the prototyping path of such designs.
Rich Brossart, vice president, product marketing at Actel said, For easy and rapid early prototyping of Actel's space-optimized RTAX-S FPGAs, Aldec's solution uses ProASIC3 FPGAs, allowing customers to tap the flexibility and reprogrammability of flash-based prototypes for multiple applications. As a result, Aldec's solution can accelerate design and validation cycles, which translates into faster time to market and lower development costs.
Substituting reprogrammable parts for the fuse-based ones requires appropriate library conversions. The primitives' library conversion utility is provided with Active-HDL, a mixed-language simulator that is included with the RTAX-S Prototyping Board. The utility allows automatic conversion
of primitives from one library (e.g RTAX-S) to another (e.g ProASIC3). RTAX-S designs not using library specific primitives or memories can be implemented to different architecture without any modifications. Otherwise, primitives and memories should be replaced manually or supplied as a
The prototyping adaptor board allows easy and inexpensive RTAX-S designs prototyping with flash devices. The reprogrammable ProASIC3 chip on the top of the adaptor allows implementing design changes easily, eliminating the need to solder/unsolder the adaptor from the prototyping board each
time the design is being changed. The JTAG connector next to the ProASIC3 device allows reprogramming of the adaptor on the fly. The power connector provided on the top of the adaptor board allows programming of the adaptor without soldering it to the PCB. Bottom part of the adaptor is
footprint-compatible with RTAX-S device allowing soldering the adaptor board to the PCB as a regular RTAX-S device. The adaptor board can be soldered/unsoldered several times, thus can be utilized for different projects.
