1 MDE based FPGA physical Design Fast prototyping with Smalltalk
Ciprian Teodorov, Loïc Lagadec Lab-STICC MOCS UMR 3192

2 FPGAs “Flexible” hardware Time to market Hard to program Hard to debug
Compute node i1 LUT µP LUT LUT I1-i2 E/S i2 LUT i1 LUT I1+i2 LUT i2 Programmable interconnection LUT LUT LUT

3 FPGAs “Flexible” hardware Time to market Hard to program Hard to debug
EDA required ! C to circuit Debug Benchmarking

4 Our Smalltalk-based EDA legacy

5 Legacy backfires Early developments (MADEO) started in 1996
Fast evolving domain (Moore + Murfy) Refactoring is not enough to keep in the race We have to re-design our framework

6 1 2 New direction We need to shift from To In order to deliver
a generic solution to be tailored on demand To a repository of model, algorithms, components In order to deliver Performances Scalability Flexibility Durability 1 2

7 LEGACY

8 Front end C code Circuit High level synthesis (compilation)
Ressources allocation (logic synthesis) Circuit

9 Programming an FPGA in 4 steps

10 ADL Based EDA generators
Spécification Architecture Architecture specification ADL Description Exploration Application Synthesizer Compiler P&R Bitstream generator HW Prototype HW Prototype Configuration Controller Testbenches Testbenches Synthesis/Compilation Compilation Simulation Simulation Validation Validation 10

11 Simulation & synthesis
Our flow Context Resources Zone Zone Zone ADL Description Reconfigurable zones description Behavioral code Bitstream model Resource model Configuration model Bistream Architecture VHDL Configuration controller Prototype 11 Simulation & synthesis

12 Some examples 12

13 RE-DESIGN

14 Goal oriented view extraction

15 Tool engine

16 Models as common vocabulary

17 Combinational circuit modeling
