System On Chip
- 1. Core Based SOCDesign Prof. Anish Goel
- 2. SoC : Systemon Chip System A collection of all kinds of components and/or subsystems that are appropriately interconnected to performance the specified functions for end users A SoC design is a “product creation process” Which Starts at identifying the end-user needs Ends at delivering a product with enough functional satisfaction to overcome the payment from the end-user 2 SOC Design Prof. Anish Goel
- 3. IP-Based Design 3 SOC Design Prof. Anish Goel
- 4. SOC Also named System-on-a Chip. System LSI, System-on- Silicon, System-on-… It used to be System-on-aboard, or System-in-a cabinet, or System-in-package (SIP) System Hardware Analog : ADC/DAC, PLL, TxRx, RF Digital : Processor, Interface, Accelerator Storage : SRAM, DRAM, FLASH, ROM Software : RTOS, IP Device Driver, Application 4 SOC Design Prof. Anish Goel
- 5. What is anSoC? An SoC must contain: Portable / reusable IP Embedded CPU Embedded Memory Real World Interfaces (USB, PCI, Ethernet) Software (both on- chip and off) An SoC may contain: Programmable HW (FPGAs, Flash) Mixed-signal Blocks Sensors Not just an ASIC ! 5 SOC Design Prof. Anish Goel

- 21. Differences in DesignBetween IC and IP Limitation of IC design Number of I/O pin Design and Implement all the functionality in the silicon Soft IP No limitation on number of I/O pin Parameterized IP Design : design all the functionality in HDL code but implement desired parts in the silicon IP compiler/Generator : select what you want !! More high level auxiliary tools to verify design More difficult in chip-level verification Hard IP No limitation on number of I/O pin Provide multiple level abstract model Design and Implement all the functionality in the layout 21 SOC Design Prof. Anish Goel
