MAPLD 2009 Presentation Poster Session Re-programmable Prototyping for Actel™ RTAX and RTSX space-flight systems designs MAPLD 2009 Presentation Poster Session

Today’s Prototyping Solution Socket + AX/SX-A Approach Good solution, but several design iterations could require several of the OTP (One Time Programmable) or Actel AX/SX-A commercial chips to complete the design. Weak Point The potential risk for using several of these OTP or AX/SX-A devices could add to the overall project cost and impact the budget.

Today’s Prototyping Design Flow Create and Verify Design Code Synthesize and Implement for OTP chip Modify and Verify Design Code N Test in Hardware: Results OK? Throw Away OTP Chip! Y Synthesize and Implement for target technology Final Hardware Tests

Aldec Re-programmable Solution Ability to prototype RTAX-S/SL and RTSX-SU designs using re-programmable Actel Flash ProASIC®3E FPGA family chips Adaptor board is footprint-compatible with the final RTAX-S/SL and RTSX-SU device Programming connector (JTAG) allows on-the-fly reprogramming of the device without detaching the adaptor from the target PCB EDIF netlist converter allows to migrate from RTAX-S/SL and RTSX-SU to ProASIC®3E FPGA easily Design efficiency is achieved, saving Development Time and Costs

Aldec Suggested Design Flow 1 Create and Verify Design Code Synthesize and Implement for ProASIC® FPGA N Test in Hardware: Results OK? Modify and Verify Design Code Y Synthesize and Implement for target technology Preferred flow for PURE HDL Designs Final Hardware Tests

The Advantages of Flash is better for prototyping than SRAM-based FPGAs: Word Select / Bias Output Input Bit Select 1 Bit Select 2 SWITCH Floating Gate Flash MEMORY Erase Program Sense Word line VCC VCC Bit Line A B Bit Line SRAM Flash switches are used in the ProASIC3/IGLOO architecture to connect signal lines to logic tile inputs and outputs. The ProASIC3 flash switch uses one transistor. Charges stored in the floating gate determine if signal lines are connected. The SRAM interconnect is larger – it contains 4 transistors and two resistors. A 6T cell. The smaller flash switch allows abundant routing resources to be placed on the die resulting in a high percentage of utilization and routability at very cost effective price points. Smaller size: more switches for greater routing flexibility Low power: less capacitance and resistance Reprogrammable and non-volatile 7
