Host Simulation ,[object Object],[object Object]

Motivation ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Prior Work in this area 1.What exists in the literature in this area? ,[object Object],[object Object]

3.What is missing? ,[object Object],[object Object],[object Object],[object Object],[object Object]

2.What has TI done in this area? ,[object Object]

Proposed Approach: What do we want do and why? : ,[object Object],[object Object],[object Object],[object Object]

Motivation(contd)…. ,[object Object],The time between traditional(hand-written) simulation and functional validation of the software increases further as the complexity of SOCs increases.This time gap should not be allowed to increase. cycles of revisions Specification Simulation Functional Validation Spec Revision Samples Arrival Final validation Ready-to-market

Motivation(contd)…. ,[object Object],[object Object],[object Object],[object Object]

b. Uniqueness (not done in Prior work section) ,[object Object],Traditional simulation implements only a subset of the architecture

[object Object],Peripherals Peripherals Peripherals Peripherals Ethernet Timer Video Peripheral Video Port DDR USB JTAG PLL CPU CACHE CO-PROCESSORS BUS DMA

Technical elaboration: ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

How should it look? Application S/w + OS + drivers HW Libraries APIs(eg:-CSL) Application S/w + OS + drivers Traditional simulation App written on a Pentium machine debugger Simulator IP 1 IP 2 IP k Core 1 Core 2 Core n Use_USB() Codec_decode() Connect_network()
