11/14/2018 Changing Paradigms - Fast-Turn RF and Mixed-Signal IP IEEE Annual EDP-2001 Workshop session on Analog/MS Design Flows James Spoto Enablix Solutions April 10, 2001
Communications Systems Challenge 11/14/2018 Communications Systems Challenge Today, the wireless & optical Industry is limited in ability to deliver timely RF & mixed signal based products Scarce skill set No standard/commercial design platforms & IP Long custom development cycle with many spins Expensive (people, non-reuse, lab) Not available (until now!) in pure-play foundries REAL -TIME AND COST GOALS DICTATE ASSEMBLY TODAY ASSEMBLY LANGUAGE IS ERROR PRONE NO ERROR CHECKING HARD TO FIND ASSEMBLY PROGRAMMERS HAMMER AND CHISEL VS. WORD PROCESSOR NO PRODUCT EXISTS TO ALLOW HIGH LEVEL LANGUAGE RF and mixed signal design cycles are pacing wireless & optical product Time-to-Market 11/14/2018
