Agenda § FPGA Design Data Center § Specific Areas of Note § FPGA Timing Closure § Current Approach § Demonstration § Cloud Approach § Going ForwardPage § 2

“Personal Data Center for FPGA Design” Simulation Routing/ SynthesisPage § 3

Confidentiality, Ease of UsePrecedents: Foundry <-> foundry customer interaction Audited Security Standards §  AES encryption §  SSL transmission §  Asymmetric keys •  Secure and Encrypted End-to-End Transfers •  Plugins to Existing Tools •  Distributed File Uploads / DownloadsPage § 4

FPGA Timing ClosureCurrent Limitations Costly Delays “Timing Experiments” §  Case 1: Miss timing by a bit §  Change a setting, repeat till successful §  Case 2 : Timing is way off §  Back to drawing board – path restructuring, pipelining etc. N hrs per iteration Drawbacks M iterations -  Takes time to re-iterate one at a time -  Usually at a later design stage Total: N x M hours -  Randomness: *Fingers crossed* -  Requires communication between “tools people” and “design people” ≈ days, weeks…Page § 5

Cloud Closure Data Center Approach §  Run iterations in parallel §  Save time wasted from waiting for each iteration §  Save time on re-engineering the design §  Use generated results from iterations to troubleshoot better X servers N hrs per iteration Total: N hoursPage § 6

Design – OR1200 32-bit processor core § 32-bit RISC § Harvard architecture § 5-stage pipeline § Virtual memory § Basic DSP capabilities § Implemented in various commercial ASICs & FPGAsPage § 7

Target Chip & Software § Altera Stratix III L50 § 65-nm technology § Logic elements: 47.5K § Package: F780 § Speed Grade: Commercial 2 § Altera Quartus II § Version 10.0 SP1Page § 8
